water bottle rocket

In science we have been making bottle rockets powered by water and compressed air. It was really fun we got into groups of two or three, I was in a group of three with David and Lucy. I was the engineer and the rocket scientist so I pretty much did everything. I designed the fins and David cut them out, I then made a logo. Lucy made a nose cone which I tuned up so it was good for the rocket. I then attached the wings.

We launched the rocket by using a wooden launch pad and an air pump with a cork on the end. We added some water and pumped the pump to launch our rocket high into the sky.

When we launched it the first time it only went a short distance until it crashed into the ground. The second time it only went a little bit further before it crashed. On the third and final time it went the really far and ended up going farther than any other rocket. I was really happy at how far it had gone and I suggest you try it too.
