I usually do this with an auto pump and bricks for a stand. Aut pumps lets you stand back and watch plus sometimes u can get a tight valve that wouldnt work for a 2 liter and use the auto pump for it

hey i used your advice, ummmm this vid , well my tire truck vales are the same as yuors but mine are so hard getting it in to the bottle, and by the time i get it in the bottle i spilled most of the water out .

how did u get yours in so easy. Some times i have to put soap on it so if can slide in easyer.

thanks one more question what pressure does it useullay blast off at

[UncleTedman]

I don't have any idea. Probably not that much but I doubt you'd want to have your face above it when it launched! :-)

[crazylaxfreak]

how do u let it rip

[UncleTedman]

When you've pumped enough air into the bottle, the tire valve will pop out the bottom and the rocket will blast off.
