    where to buy water glass:

An art store or an automotive shop is likely to have it. It might be sold under its chemical name of sodium silicate instead (also, it’s often sold as a solution instead of the dry chemical).
Alternatively, if you live in the US, an automotive dealer might have some left over from the “Cash for Clunkers” program that ended a few hours ago that you could buy cheap. The approved method for disabling the engines of cars traded in under that program was to replace the oil with sodium silicate solution and run the engine until it seized and the car would no longer start.
