On Monday we were doing some science.  We were doing helicopter science.  The first one we made spun quite well but it was a little hard to make it turn. On our second one we had to add 3 paper clips and see what happened. I discovered that it went a lot smoother and it was a lot easier to turn.  The next thing our teacher asked us to do was to cut the wing in half.  I discovered that it went quite fast.
