Even more rocket fun!

Our latest rocket experiment involved trying out different shapes of rockets to see which ones flew best. This time they were powered by a puff of air.

We made these ones with paper cuts outs and stuck bendy drinking straws on the back. The straws had to be bent so that the air did not go right through.
We flew them by putting them into a wider straw and puffing air into it.
We measured how far they flew.

We realised that it was important to make sure the rockets were powered by puffs of equal strength to make the test fair. Also we had to start at the same point. The rockets were all the same length too but had different shaped wings or bodies.

Here is a short video clip to demonstrate our techniques!
