Year 6 tech

A couple of my friends and I have been making cars. We have started making boats. We just tested our boats today to see if the would float. We could only use tinfoil to make the boats and we weren't allowed to use any other materials otherwise it wouldn't be an experiment. When we made the boats we only took about 20 mins as when we made the cars it took about 1 hour.

This is our car I and Bella made this.
