Water fuelled rocket

Yestarday i bought a water fuelled rocket from school. When i checked the components inside, i was quite disappointed as there was not many things inside, and it cost FIFTEEN DOLLARS!!! ARGH! i spent so much money on pieces of plastic and i feel that i was cheated. But, when i tried it, it was not that bad. At first when i taped everything i tried it without any water. Then i pumped... and pumped... and pumped... then suddenly, i heard the sound of an explosion. I realised that the cork that was blocking the opening flew out. But everything else was okay. i didnt know that it would make such a loud sound.

At night.
At about 8.30pm, i went out to try it out. It worked perfectly. Was very fun. Did it many times untill tired and went back. bb

Time 2 learn mo xie!
