Rockets!

this post is all about rockets. some are functional and some are just for looks, but they're all easy and fun to make.
this first one is an awesome little rocket which is powered by air. if you pump hard enough, it can get quite a bit of air. i built one back when i was in primary school, which shows you just how easy it is to make. this is one very cool rocket.

this second one is by far the easiest to make. all you need is a straw, a sheet of A4 paper and some glue or tape. when you have made the rocket, all you have to do is blow into the straw and watch your rocket soar through the air and shoot toward whichever target you have chosen.
