This is my method... works well.. very clean..

oh!! AND U HAVE TO STUFF SOMETHING INTO THE BOTTOM OF THE PAPER.. OR JUST TAPE OVER IT SO THEY DONT FALL INTO THE SODA RIGHT AWAY.. ( duh) SORRY..[/b]

errm i jsut poor out half of the diet coke and put 1 menos in the cap and screw it on REALY fast. then u have to hit the cap on the ground or something (kinda hard to do). i wasted like $30 tryin to figure it out

it wont be very effective, there isnt enough pressure to lift the whole bottle. not to mention all the presure will leave the bottle when its full there wouldnt be constant pressure allowing it to maintain flight. the most youd get is like a meter or 2 of flight.

they did this shit on mythbusters but you can piss someone off by shooting a line of foam at them lol but that would need a ton of lift to get off the ground and it doesnt have too much force

we get consistent results... works almost every time... sometimes my friend ( mark ) is an idiot and throws the bottle down wrong so the cap smashes in and the bottom blows out

why dont you just get some dry ice warm water and a fucking 20 oz bottle fill the bottle half way with water put a few small pieces of dry ice in it stick your finger in the hold hold it on as tight as you can dont worry those bottles need at least 200 psi to blow up with out impact i know from expierience and when it is to tight to hold on anymore let it go pointing it at the sky or at a friend whatever it is fun i was doing it all halloween

What's easier to get, mentos or dry ice?

hmm....aparently, both can be gotten from a gas station, so i suppose they're about the same difficulty to get....

who ever said it would launch the entire bottle...
