Do you know how to launch a plastic bottle up high in the air

Then you put the pump on the aquapod/ water rocket you then step on the pump at least 8 or 12 times so the water bottle has pressure so it goes up high we did 12 pumps and when my teacher pulled the string  it went pretty high. I enjoyed it a lot you should tell all of your friends about it and begg you teacher to do the  Here's a link to the video.
