Re: One upping Dave: A Diet Coke and Mentos Rocket!
Correction to my earlier post (controlled Diet Coke Mentos Rocket Launch)..
It seems that using 4 mentos instead of 5 is too few and the rocket will
not have enough thrust to push out the cork sometimes. So add a fifth,
but to get all five flush with the cork and above the soda you have to
squash them by about a third. This does not harm the reaction but you then have time to cork and overturn the bottle!
