As requested an update with how to embed the Apple and the color of spray paint.
i used a circular glass drill bit like this one. i got it at my local hardware store but you can prolly find it at a HD or Lowes. just make sure when you drill you use a lot of water or your glass will have a greater chance of breaking and the drill bit will get ruined from the heat generated by the bit
General outline straight cuts using a wet tile saw, then use tile snippers for countouring.
There's a lot of options for drilling the holes.
Good question.
I bought a locally made hookah (DC area- base with stem) from my go-to hookah shop. Had a dremel handy so with a few modification, the fit is nice and snuggly. I had to cut the downstem to make it shorter and after making the neck smaller using the dremel, I ended up using electrical tape instead of a grommet and it suprising works great.
If you are unable to find a stem that you can modify, you can create a downstem by using refrigeration copper coil and sealing it by putting epoxy on the cap.
You will also have to make a hole for in the glass using a diamond dust drill bit for the hose. You can find all of the parts from Home Depot. You may need to create another hole for a clear valve and buy one of those parts for glass hookahs to serve as a clearing mechanism. I did that a few years ago with a grey-goose bottle and everyone loved it. However, it was short-lived due to the extensive setup and breakdown time lol
That hookah idea was was inspired off of this article but I didn't like some of the parts used.
Hope this gives you some ideas.

I bought this. Way less expensive, works pretty good too. https://www.amazon.com/Bench-Dog-Tools-50-37801-Beadlock/dp/B008FYISBG
The Beadlock jig. It's like a poor mans Domino!

It's a glass drilling bit. You can bit them in a home improvement store as well. 3/8 takes bong hitters, 5/8 takes female connection for glass on glass
So you are going to pull up the patio, expose the pipe, make a new connection, and bore/chip out a hole in your concrete garage wall to pass it through? Is that right?
Use a hole saw designed for concrete. Many of them are designed to mount on a high sppe angle grinder. Here is one example:
https://www.amazon.com/DAMO-Diamond-Concrete-Granite-Marble/dp/B005IEIUSC
Pray you don't run into any rebar.......
Then run you pipe through, fill the void around the pipe with hydraulic cement:
http://www.homedepot.com/p/Quikrete-10-lb-Hydraulic-Water-Stop-Cement-112611/100318494
Once the void is filled, use some foundation coating around the pipe on the exterior, as a backup to prevent water from leaking into your garage:
https://www.walmart.com/ip/Tamko-Nonfibered-Roof-And-Foundation-Coating/174321639
It's basically just tar. There are synthetic formulas, and they work quite well. You just need something as a backup.
There's the beadlock https://www.amazon.com/dp/B008FYISBG/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1QXUNLTAU6H35&coliid=I3WC28W1JW537
Reviews are mixed on it, I've never used one.
Too late for this, but easy outs are NOT for use with seized screws. They are only for use with screws whose head is buggered.
I wrote this up a while back, you should give it a read:
Best tools for removing broken or stripped screws.
As for getting the easy out OUT, there is another option, but you need some crazy tools. Mainly a drill-press stand for your hand held drill, and a hollow, diamond coring bit, like what you would use for drilling a hole through glass or ceramic. If you can cut around the easy out with the coring bit, then you can break it free. Next, you finish over-drilling the hole, and then insert a threaded insert to bring the hole back down to the correct size.
Parts I'm talking about:
Drill guide The drill guide is important because the coring bits will walk all over the place since they don't have a center point. The guide can be fastened, held, etc. in place better, and help guide the bit to where it needs to go.
Core bit
You can also use a more standard bimetallic hole saw, just without the pilot bit installed.
Threadsert (Choose the ID of the original fastener, and find it in SS, not carbon) Don't use a Helicoil, those things are shit. (Speaking from LOTS of experience here...)
Two taps that match the outside threading of the threaded insert. One a taper tap, and one a bottoming tap.
The cheapest way is to use something like this, then knock the pieces out and continue the drill process:

9 dollars is pretty cheep
Oh no my friend, I paid $15 for a single bit and it doesn't resemble yours at all.
Give http://www.amazon.com/DEWALT-DW5572-4-Inch-Diamond-Drill/dp/B000VR7E60/ref=sr_1_2?ie=UTF8&qid=1369220278&sr=8-2&keywords=diamond+drill+bit a try and it will change the way you look at glass projects especially if you have a press.
I cant even imagine the things I could do with a press and a quality bit haha
drilled out a few screws in motherboards and graphics cards with a set like this but you have to have a steady hand
This is what worked for me you can enlarge the hole a bit with the bit :-) DRILAX

So I'm not a machinist, just a lurker here but this is something I know about so I'll give my 2 cents. I sold these for several years and this is by far the best bit for drilling granite it's a dry bit and will work just fine that way or you can use water. It's designed for angle grinder use so it's good up to 12K rpm, and honestly the faster the better. The Alpha rep told me this, helps you get through the piece faster and keep the bit cool. Now it's designed for 1-1/4" countertops so maybe give it a cool off period after an 1" or so on your 3" surface plate, water will also help keep it cool. Feed pressure will be minimal as well as pushing too hard will glaze the diamonds and temper the matrix they are suspended in, they are designed to slough off and reveal the next layer of diamonds so getting it too hot will prevent that. It's 5/8-11 so you will need an adapter of some sort no doubt. Don't know if this helps or not.
How much money have you got?
Amazon is the way I normally go...
Dirt cheap (and probably shitty): https://www.amazon.ca/TITANIUM-COATED-DRILL-METAL-PLASTIC/dp/B00O3M81CA/ref=sr_1_3?ie=UTF8&qid=1521243188&sr=8-3&keywords=3%2F32+drill+bit
Better: https://www.amazon.ca/Irwin-73106ZR-32-Inch-Turbomax-12-Pack/dp/B00ALTDZ02/ref=sr_1_19?ie=UTF8&qid=1521243213&sr=8-19&keywords=3%2F32+drill+bit

I'm curious about these: I've used cobalt before and been impressed when working with hardened steel: https://www.amazon.ca/DEWALT-DWA1206-32-Inch-Industrial-Cobalt/dp/B00SOU4A3Q/ref=sr_1_7?ie=UTF8&qid=1521243188&sr=8-7&keywords=3%2F32+drill+bit
Any carbide or diamond toothed hole saw will work.
Here's one:

You'll also need to purchase an arbor. Make sure to keep it wet while you cut; both to keep the dust down and keep the bit cool.
