|On Friday Room 7 made Hovercrafts We used…
A bottle top from a pump bottle
A piece of blu-tack
First we filled out a prediction about how we thought it would move,how far it would go and the distance it would travel.
When we finished that,we went to a spot to experiment.
How to make it…
1. I got my CD and put blu-tack around the hole.
2. Then I stuck the bottle cap on,by making it stick into the blu-tack.
3. After that I blew up the balloon and stuck in onto the bottle cap.
4.Then i experimented with different kinds of surfaces,Eg. wood carpet and lino.
It worked the best on the lino because it was slippery.
Harmony was choosen to test hers out on a incline.
At the end we had races to see who’s would move the fastest.
