Have you ever seen or used a water rocket?

Do you know what a water rocket is? Today in class for science we are going to launch a water rocket into the air. I think that rocket will go five meters in the sky. Because of the water in the in the bottle will push up because of the air pumped in the bottle. The force of the rocket was very strong causing the air to escape and the water to go down. The aqua pod helped the bottle stay in place it is a very useful launch pad for water rockets. We used a pump to fill the air in. The water in the bottle was one third full of water. Our first launch off was not very successful.

We used the pump and pushed the pump with our feet eight times. We did a second attempt. Our second attempt was way more better than our first because it didn't work. The water bottle went about eight meters nearly about  so close to ten. There was also a third attempt where we went even higher than before. We went thirty meters high into the sky. We had to pull the string for the rocket to go. We had so much fun doing this with our buddy class and our teacher.
