Re: One upping Dave: A Diet Coke and Mentos Rocket!
if someone is really working on a Dcoke/Mentos rocket then 'studies' have shown that water-rockets get the best altitude when they are about 33 to 45 % full.
It would be interesting to see some tests with the bottle plugged with something designed to release at a preset pressure buildup (like a cork) instead of the screw top
and please, beg/borrow/steal some safety glasses. Ive never met a blind engineer.
