Hell, they even make fake tampons designed to sneak alcohol into venues in. It's totally possible.

u/farptr · 19 pointsr/whatisthisthing

It is an unblown plastic soda bottle preform. They're sold as water tight small containers so this could have been used for anything.

u/plazman30 · 10 pointsr/Aquariums
u/Nyxian · 9 pointsr/trailmeals

Salt & pepper covers me most of the time. Occasionally I'll want olive oil. I use small plastic test tubes with screw lids. They are 5.08 grams and 10 cents each, and hold 15ml. For reference, that would be about 140 calories of olive oil.

The amazon link says 10ml, however a quick water test shows them holding 15-16ml.

They are strong and durable, and resistant to being crushed. Also really useful for medicine or other things you might need to bring along.

u/jake_kulp · 8 pointsr/whatisthisthing

Definitely looks like a geocache made from a soda bottle preform. would explain the 'fish eye lens' and the soda bottle style cap.

u/AryaStarkRavingMad · 8 pointsr/TrollXChromosomes
u/Pac_management · 7 pointsr/Homebrewing

They are actually made for soda bottle production. You can usually find big packs for cheap.

u/MachinatioVitae · 7 pointsr/Survival

Hey, thanks! Yes, that's the one I was thinking of. I just couldn't find it. Idk about better though. They're different for sure, but they're both made from bottle preforms, so the tube strength should be the same.

The pocket reel comes with:

  • 1 pocket reel
  • 4 fishing hooks
  • 4 removable sinkers
  • 2 metal spinner lures
  • 3/4" bobber
  • knot guide with directions
  • 45' spool of fishing line

    The one I linked comes with:

  • 1 Heavy duty plastic tube with screw top lid.
  • 24’ of 20# monfilament fishing line
  • 3 #2 Eagle Claw Hooks
  • 3 #4 Eagle Claw Hooks
  • 4 #3 Split Shot Lead Sinkers
  • 4 #7 Split Shot Lead Sinkers
  • 2 Slip Bobbers
  • 2 Attached Bobbers
  • 2 Various colored Jigs

    So, with the pocket reel, you get 4 hooks instead of 6, 1 bobber instead of 2, 4 sinkers instead of 8, metal spinners instead of jigs, but almost twice as much line and a "knot guide".

    Seems like about a wash to me. I should note that I don't have a horse in this race, I've never used either and am not affiliated with either shop. The kit I posted was one I found a month or so ago while looking for the one you posted.

    Personally, I went with neither and just bought some bottle preforms for about a buck a piece, filled a couple with the fishing gear I already had and used the rest for other camping gear: spices/oil for cooking, match case, pill bottles, tinder case, etc.
u/VinPeppBBQ · 7 pointsr/Homebrewing
u/neuromonkey · 6 pointsr/geocaching

They are soda bottle preforms (or "baby soda bottles,) which are uninflated 2 liter soda bottles. Available here and on Amazon, and other places.

I must say that posting a "these just arrived in the mail" without providing a source is a little less helpful that it might be. OP? Your source?

My problem is its always easy to “if I have that it’s hardly any more to include this” myself into a monster pack

Mine is a 3.5 x 5.5 x 7” soft pack that weighs 30.5 oz

Bottle preforms are great small tubes for keeping things dry

For a while you could buy redbull shots. They were a great small container as well

edit:correcting formatting.
Edit 2: always put rolls of tape in a baggy. When theyre hot they can ooze adhesive and make your kit a mess

u/Davec433 · 5 pointsr/Homebrewing

I use Soda Preforms and freeze by filling half the container with yeast and topping off with a 50/50 solution of starter beer and glycerin.

I then put in an insulated bag with an ice pack to protect from freeze/thaw cycles.

The only thing I’d change would be to MAYBE use 1.5 ounce glass jars. Which you could keep longer and straight up boil to sanitize.

Soda Bottle Preforms and Caps (30/pk)


They are commonly called test tubes, and used as such in an amateur setting. They are also known as this other thing though. The original intended purpose.

u/ElitistRobot · 5 pointsr/funny
u/keirx · 4 pointsr/fountainpens

You can buy vials from Amazon or [Goulet] ( And you can get blunt syringes from [Amazon] ( or Goulet as well. You can also use any small glass or plastic vial you might have, I recommend small spice or jewelry jars. You can often find them in craft shops if that's easier and more local for you. Blunt syringes aren't as easy to find in person, but you can often find wood glue syringes like this in any local woodworking or craft shops.

u/yeahimageek · 4 pointsr/trailrunning

I bought a 50 pack of these plastic Centrifuge tubes for mixing on the go. One 50 mL tube holds almost exactly a single serving of Tailwind. Plus, I can fit two full tubes in the storage pouch of my Nathan SpeedDraw plus. I used this setup for a Marathon and a few trail races and it worked great. The tubes are so cheap you can dispose of them if you want, or save and wash them for reuse. Much better than the formula dispenser option you're looking at IMO.

Edit: Here's an updated product link to what appears to be the same item, but is in stock.

u/Reinheitsgebot43 · 4 pointsr/Homebrewing

If you’re going to do that you might as well freeze it in soda preforms (take up less space) and slowly create a yeast bank.

u/LegalizeGayPot · 4 pointsr/vaporents

If you don't have a vape yet, get an Arizer, you won't regret it.

As far as containers go, check out bottle preforms. I bough a 100pk of these years ago and still have half

Personally, i bought some soda bottle preforms ( and overbuild starters, save a vial or two, and use that to rebuild starters. Havent bought yeast in a hot minute.

u/reverendj1 · 4 pointsr/Homebrewing

Here's a post I wrote detailing how I slant yeast. The process is pretty simple, and only requires mason jars, test tubes, an innoculation loop, stove and pressure canner and a few consumables. I've tried several other methods for storing yeast, but this is by far the easiest, cheapest and most compact. You only need a pin prick's worth of yeast to create the slant, and you only have to maintain them every 1.5-2 years (which is also very simple). This makes it so you can accumulate quite the bank! I currently have a bank of 23 yeasts, and it fits in the size of a shoebox. The only thing I will note is that the test tubes in my blog can be expensive. I recently switched to these centrifuge tubes instead, as they are much, much cheaper, and they should work just fine, reading the comments, but I have not tested them personally yet, so have not updated my blog. The only downside to doing slants is it does take about 7 days to get a pitchable amount of yeast, so you have to be able to prepare ahead of time.

It won't be impossible, it will just mean using a different container. I've been holding onto a ton of the tubes for a while for saving yeast. Also:

u/wonderboy37 · 3 pointsr/AskMen

u/chino_brews · 3 pointsr/Homebrewing

The water probably does more harm than good. If you need some liquid to cover the yeast, use American light beer/Intl. pale lager.

For centrifuge tubes, /u/theJexican18 use skirted centrifuge tubes, $14 for 50 tubes.

For any fam that wants this, Amazon's gotchu!

EDIT: They're actually a bit cheaper at Educational Innovations, its the second link when searching for where to buy unformed soda bottle.

u/Kush420coma · 3 pointsr/trees
  1. It's a tube where you pour alcohol in it and put it in a faux tampon wrapper so you can sneak it around. In my case, I've used it to put my blunts in it for my boyfriend and I for Mad Decent Block Party this Saturday. (Currently on a t-break, excited to smoke again in a couple of days!)

  2. Yes! I love that picture. I bought it from Salvation Army a couple years back. I use it as my blunt rolling station.

u/tubasco · 3 pointsr/GrassHopperVape

I use a Santa Cruz shredder and store it in these:

There are plastic ones too, (doob tubes) but I prefer the glass.

Just pour the shredded into tube and pour into hopper. I shake the tube before opening it to loosen the pour.

u/lordfili · 3 pointsr/Homebrewing

So I uh, cheat, and use Northern Brewer's Fast Pitch. I absolutely love this product as it means I can whip up a starter in ~5 mins before leaving for work in the morning (because inevitably that's the only time I remember I need a starter for later in the week). If you'd rather make your own starter wort, it's pretty simple - all you need is DME, and the measurement can be calculated here.

Otherwise, my method is the same as /u/pricelessbrew's above, which was originally from /u/brulosopher here. As I mentioned, I use centrifuge tubes for storing yeast - this actually was a method someone here suggested on a daily Q&A thread a few months back that I can't find now. Containers are cheap enough to only use once, and are pre-marked with volumes to be able to estimate cell count. Highly recommended.

u/PerilousAll · 3 pointsr/crafts

Really nice! I thought you probably put an inverted test tube up through and above the base before the resin pour in order to get that much light inside.

u/mr_cfromcali · 2 pointsr/Saionara

Yes, those should fit as well. Hmmm, I may need to give that curved one a try, too.

As it happens, I also ordered one of the pieces in your second link, with the plastic mouthpiece ( ), so I have one on hand, and yes, it also fits the Sai with a section of cart cap as a seal. I'll post a pic when I have some time.

These were so cheap that I ordered a few others at the same time, so I have a few more coming. I'll post the ones that fit, but the one I highlighted does work great.

u/mks113 · 2 pointsr/mildlyinteresting

2 litre soda bottles actually are shipped as preforms that can be expanded before they are filled. I guess heating them up without pressure returns them towards their original size?

u/Drakonaf · 2 pointsr/CampingandHiking

I use a small Coca Cola bottle they used to sell. 150ml I think. I also know you can buy a 2L bottle in it's pre-inflated state. Soda Bottle Preform

u/KTBFFHCFC · 2 pointsr/Homebrewing

I bought 50 of these back in 2015 and have a ton of them left. I swirl the starter and decant off enough to fill 4-6 tubes to the 45-50 ml mark. That usually gets me 15-20!ml of yeasties once it chills for a while.

u/Joma449 · 2 pointsr/mildlyinteresting
u/carlodelpizzo · 2 pointsr/mildlyinteresting
u/JustPandering · 2 pointsr/Homebrewing

I built this for about $20 (not including the erlenmeyer and the stir bar).

I got the cigar box a while back at a second hand store.

Here's the USB powered PC fan I used:

I chose a usb fan so that I could power it with an android usb phone charger and not screw around with splicing wires.

Here's the magnets I used (just needed one though):

Aside from that it just took a few odd nuts, washers, and a bit of superglue. I had to bore the hole in top of the cigar box because the box turned out to be a bit too thick (sorry Pepin Garcia!) to get enough attraction between the magnet and the stir bar. I think I might have had better luck with stronger magnets or a different stir bar but oh well.

As someone suggested I first glued a washer to the fan so that I could move the magnet around a but to find the sweet spot where it didn't shake too bad then I glued the washer in place.

I used the long bolts/nuts that came with the fan to attach it to the lid (you can see the bolts in the first picture). Between the top of the fan and the lid I had to add washers to keep the fan from rubbing on the cigar box.

That's pretty much it. The fan has a variable speed control but I get a small vortex on the lowest setting, and higher settings throws the bar off the magnet.

Now I just need to wait for my soda preforms to show up so I can start saving a bit more yeast after I use the stir plate!

I got the idea for using the soda preforms from here:


u/rainmanak44 · 2 pointsr/Homebrewing

Have you considered bottle blanks? Pretty cheap option and just like what White labs used for years. Bottle Blanks

u/SloppyJoeBeaver · 2 pointsr/OutlandishAlcoholics

Have a guy place it next to the frank and beans. A bulge is normal and the door man isn't likely to touch there. Or there's always the Wine Rack or the tampon flask.

u/mousec7 · 2 pointsr/TrueBlood

Doing some sort of shot into these might be appropriate. They're cheap enough and a bit of gold paint from craft store might be enough to glam it up.

u/PUHDBAS · 2 pointsr/vaporents
u/AutumnRustle · 2 pointsr/MushroomGrowers

You're welcome -- glad I could help!

If you decide to go with large tubes, these are similar to the tubes I use, but there are cheaper options: 1, 2, 3, etc. It's important to look for tubes that are listed as either "sterile" or "autoclavable." I like the pre-sterilized packs because that's less work for me.

There are a lot of techniques out there, so sometimes it helps to list them out into categories with a few details underneath each. With a list like that, you can go through it all at a glance and decide what aligns with your budget, material availability, and level of effort/interest.

Let us know what you end up deciding to do and how it works out for you. I'm sure a lot of folks around here would like to see it!

u/Maeby78 · 2 pointsr/funny

These fit nicely in your purse, and security never messes with them too closely.

u/Elk_Man · 2 pointsr/Homebrewing

Assuming your pints are partially filled with spent wort, you can siphon that off and just fill old White Labs tubes with the yeast. If you don't have any old tubes kicking around you can just grab some of these

u/esseffgee · 2 pointsr/CampingandHiking

Oh wow, I'll have to give these a go. I've been using a few of the Nalgene Travel Bottle Kit bottles for olive oil, hot sauce, etc, and soda bottle pre-forms for batteries and some other stuff. But they're too big for most things like seasoning/spices, and not big enough for stuff like pancake mix.

u/bskzoo · 2 pointsr/Homebrewing

I've got 14 different strains right now by my last count. Just stepped up a frozen Imperial Juice last night and I'm stepping back up a frozen Bell's House yeast as I type this.

I use these but it doesn't seem they're for sale anymore. In any case, any 50ml vial will probably work.

My normal routine is to make a 1.5L starter in a 2L flask and decant off most of the supernatant after the fermentation is complete. I try to swirl in a little just to make sure that the yeast isn't too thick and can actually pour. A semi-thick starter like this, for me, will usually fill 6-8 50ml flasks up to the 25ml mark.

Starter calculators are a wild guess at best in terms of actual cell counts, but if I can suppose that I have close to 30-40b cells per vial I'm usually okay with that amount.

For glycerin, I use a 10% mix total (20% mix into the vial). Usually 1 cup of distilled water and 1/4 cup of glycerin will be plenty for my fills. I'll take this mix and stir it together in my instant pot. I cook the mix for like 3 minutes on high pressure and then release it. I'll take the pot out of the instant pot and let it cool with the lid on.

Once my glycerin is cool and my yeast is decanted I'll fill as many 50ml vials as I an with a 50/50 mix of each slurry and glycerin. I'll label them with what the yeast is, date it, and add what generation it is. I haven't gone beyond 3rd generation, I figure if I can get something like 15-20 pitches out of a pack of yeast I can leave it at that. I'll also label the cap of the vial too so I can identify them easily when looking at them from above.

Once they're all full I stick them in the fridge for 24 hours to cool. After that I'll take them down to my freezer and shake them all up again before sticking them into a styrofoam container that I keep in my chest freezer. The styrofoam helps protect the yeast from freeze / thaw cycles.

When I want to make a starter I try to plan it a few days in advance. I prefer to thaw the yeast vials in the fridge for a day, but soaking them in a bowl of water for an hour has seemed to work just fine as well. I make a mix of .1g per ml starter wort depending on my needs (usually back up to 140g in 1400ml or so) and pitch the thawed yeast. It's usually about done in 18-24 hours! That gives me enough time to cold crash it a bit so I can pour of the supernantant for my actual pitch into my wort.

u/Stinky_Fartface · 2 pointsr/Homebrewing

I do a similar thing, but these are the tubes I use. I bought two sets of them several years ago and they still work great. I replace the caps every so often. For the rack, I just keep them in six pack holders and put them in the keezer. I fill the unused vials with StarSan solution and store them that way.

I'd also like to add that, after I have racked a new beer into the fermentor, I pour the leftover trub into a mason jar, and then let it sit in the fridge for a day. Usually the trub separates to the bottom leaving a fair bit of usable wort. I give it another quick boil just to make sure its sterile and then make a small starter of something. After pouring off much of the beer, I can usually get about 10 vials of slurry.

u/baconbabe456 · 2 pointsr/weddingplanning

I am struggling with this too, so I will take notes from this thread (thank you).

What I am doing thus far:

tampon flasks because I found them online and thought they were hilarious, and my girls are similarly natured

A mini bottle of her favorite alcohol for each lady (they are all of age)

Custom compact mirrors that I found on etsy; I can customize one for each gal based on her interests (one is getting a disney themed, one is getting PSU, etc)

A necklace to wear for the wedding (so technically not a gift, but they are beautiful so hopefully they will like them anyhow)

Also providing mani/pedi the day before (well my MIL is gifting this to us, so SHE is providing that), hair and makeup for the service, and getting ready food (breakfast and lunch).

As far as other gift ideas though, I am completely clueless. I wanted to make little gift boxes or wedding survival kits for each of them, but I dunno yet.

u/Chernoobyl · 2 pointsr/StonerEngineering

Bought some plastic vials off Amazon, fit perfect in my bong. I used an exacto knife that I heated with a lighter to cut into the plastic. Made a few different patterns, the wrap around one works really good, gives a nice clean pull.

u/downvote_syndrome · 2 pointsr/Homebrewing

Cheap 50ml tubes and a rack for them.

They aren't pressure safe like the preforms are, so make sure you're all gassed off before you seal it for long term.

I usually keep it in a jar with the lid loose for a while before I decant and move the slurry over to a tube for longer term storage.

Right now I've got only six strains, but I only recently started harvesting from starters. My go-tos tend to be:

  • WY3711
  • WY1010
  • WY1272
  • WLP007
  • WLP090

u/SUICUNE_FUCKER · 1 pointr/ants

I got 60 when I bought mine and I'm currently using about half those. Buying in bulk tends to be cheaper over time as well. The ones I carry on me as "just in case" tubes haven't gotten pretty cloudy due to scratches and oxidation and a few have even cracked a bit just from being carried around constantly. I think I've managed to straight up lose two of them to top if all off. Not a terrible investment and they can be used for other things as well.

Here is what I'd probably get in your case OP. I'd soak them in soapy water and thoroughly wash them out first before I'd use them. This one is pretty good as well if you're not looking for any large species like camponotus. Down side to these would be they're a little small in terms of diameter so they wont really plug and play with most formicariums you can buy.

Personally I'd go with the first option. Its pretty proven and the smaller tubes will probably run out of water quicker. Oh, and its a lot easier to get queens into a larger test tube. I really need to get some larger containers for captures.

Here's a link to those tubes. They're pretty common, you might be able to find a better price than that.

They're food-grade (obviously) so they supposedly work well. Haven't used them myself though. These should only be used for starters though. After storage you're likely not going to have enough viability in a single vial for a healthy pitch.

You need to make some slants. Petris in the fridge dry up and end up with water matted on the surface.

check these out . I haven’t used they yet, and make sure you get a tray so you can PC them. I’ve used the glass ones, but those are really expensive.

Warning - they do come in a BIG bag - 100 count. WAY too many for me to ever use. If you live in Seattle - come over and I'll give you a bunch.

I've also ordered bottles on You may have better luck there since you can by just the amount you need.

I make a starter for every yeast that I buy and then save a little bit in 50ml vials. If I ever want to use a yeast that I have I just create a starter 3 days ahead of brew time. I used to use mason jars, the 1/4 pint ones (4oz I think) but found out that these take up way less space.
