Pretty easy bottle rocket

Well... this is my first instructable so just go with the flow...
its a really easy and effective bottle rocket it goes like 60-70 feet in the air if you get it right. here are some pix of the one i made. it actually is easy so MAKE IT LOL!!!!

Step 1

first you need your equipment:
1: PVC Stand
1: 2 liter bottle
1: bike pump
1: tire stem
1: roll of duct tape
and a source of water
if your tire stem fits perfectly into the bottle you don't need the duct tape cause all u do with the duct tape is make it fit.

why do u need water? what  does it do to make it better?


i have no mean to be mean just wondering why

[supersonicboom]

i don't know the science behind the fact that you need water, you just do.  if you don't believe me try it with just air... see what happens

[supersonicboom]

oh, i just found out. the water has 2 purposes, one is that it works like a propellant, and creates thrust.  The other reason is the air forces the water out of the bottle, which extend the amount of time for the pressurized air to come out of the bottle, which allows the bottle to go higher.  that's why you need water.  pretty cool, huh?
