On Friday we had the challenge to create a reaction contraption. This meant that we used a whole lot of junk, toys and games to make some wacky reaction tracks.
From racing car tracks to toilet roles, cricket wickets to dominoes, and marbles to tin cans. We had a lot of fun making these, continuously modifying and adapting until we had the perfect, or not so perfect, contraption.
Check out these movies we made to see what we mean.
