Pyrex, take 1

i'm learning how to work with pyrex...
these are flower pendants...... they are also called 'implosions'.
If you click on them - the actual image is pretty big and you can see a decent amount of detail.

I need to get my act together and figure out a way to take my setup into the Vinery for a little help attaching the regulators and stuff that I don't remember how to do. yeah. i feel silly. i've been taught how to do it before... but suddenly, when it's my hosue we're talking about, I get scared about exploding my garage or something. That would be A Very Bad Thing.
