So I've been waiting for almost two months now for my mimosa to arrive (SCREW YOU CANADA CUSTOMS!), and I might as well get everything ready for when (if?) it does arrive. I want a smoking device that is portable and easy to use, so I was thinking of making a mini-Machine but I have some questions...

1. What's the smallest size bottle that can be effectively used? Obviously I don't want my Machine so small that I can't get decent hits. I'm considering using a small 30mL amber dropper bottle. Most pictures of Machines I've seen use larger bottles, so will something this small work? I attached a picture of it below.

2. How exactly does one drill a hole in glass? I'll be putting my mouth on it so it has to be smooth. I have a ceramic tile drill bit, and a Dremel but it doesn't have the right attachments. Someone here has to have some tips for drilling glass. I'd rather not break the vial as they aren't that easy to get (Need to buy them full of a supplement/tincture and empty it).

When I made a machine I just used a regular drill bit. Just don't apply much pressure let the drill do the work as pressure will break the glass, and when the drill bit/glass heats up I just kept cooling it with cold water. It took awhile but not to hard.

That is very similar to the one I had my first breakthrough on.
I (carefully) cracked a hole in the bottom then taped a straw in it and seal it.
Drillbit would definitely work better, I'm just saying that is what I did.

Get a COPPER kitchen scrubber and either torch it all around with a lighter or stick it under a pot on a MAX element for a minute or two.

Once your copper is burned and the right size then it is very hard to mess anything up. Gently melt the DMT onto it and you're good.
If you heat the ball really hot then the smoke will be harsher and if you heat it gently it will be smoother but either will give you the same effects.

Good luck

I bought a glass drill bit for a few bucks at the hardware store. It worked on some really thick glass it just took patience.
