The truck carries food on it's bottom floor. The wind or air blows and hits the sail. We used straws & thread spools & string & three hooks. Max & Geoff used the same idea as ours. Theirs & ours are both deliver food. Both machines have sails. Our idea comes half from a sail boat & half from a truck.


We had trouble trying to lift up the tray that the food was on. The back of the tray wouldn't stay straight so we put weights underneath it. We had trouble making the lifts. We solved the problem by using pulleys.

Reminds me of . . .

It reminds us of half sailboat and half pulley.
