Water bottle cap rocket

Step 3 Rapid pressure release

whilst still holding onto the bottle with both hands (right hand on top and left hand on bottom), take your right thumb and VERY quickly screw off the cap. if you did it right the bottle should make a popping noise and the cap should fly about ten feet away. im only thirteen and have no clue how to upload pics, so please dont ask for them.

guys, when you have it twisted hold it with your left hand toward the bottom. Then, at the top, hold with your right hand and place your thumb firmly on the cap. have it unscrewed a little bit already when you start. then, with your thumb firmly against it, twist quickly to the right.
