I'd love to make this or even buy it but I don't have the money for that, also it's carcinogenic, but what isn't these days.

Nice video. Thanks for the link Grenadier. It is more and more difficult to get stuff to do anything these days. Fortunately the "mothers against everything" are now in control of schools these days so the next generation will be clueless about everything too. Dont forget to wrap yourself in bubblewrap to go to the wellfare office....

Safety mongers annoy the crap out of me. I am deeply saddened when I see things saying to wear gloves and goggles why using baking soda. It's plain rediculous, you don't used a high power fumehood, thick rubber gloves, face shield, and lab apron while cooking do you? Same with dry ice, if you get burned by dry ice, your an idiot, or have no sense of pain, because it hurts badly before it even burns you.

On a side note, does anyone know if Ebay actually hand over details of people bidding or watching "items of interest" to the authorities, such as certain chemicals?

I've got TEOS, but no chamber to dry the finished product in using CO2. are there any atmospheric ways of drying out the stuff?
