Recap last few lessons

I was away Monday, and I am away again. Laura fixed our broken arm. She reinforced it and it looked really good. She also drilled the holes for the wheels to go and made the base more sturdy.

So Tuesday I glued the wheels on and made a release system for our trebuchet. I used two nails and two elastic bands. it became quite a effective way to release the arm, though it may not me the safest way. 

Trigger system (2 nails and rubber bands)

Ready to launch

 Mr Ward also helped us a little bit that day. Here is a picture of him being the awesome teacher he is.

Since I am away today as well sick hopefully Laura has fixed any problems that arose during testing and she has gathered some information for the theory part of our assignment. I hope she has.
