My activity

Today just before i was playing the game called 'Physics' on the program sugar and made my own sort of game where you make a ball and try to get it to go right round and back to the start, i used the motor tool to make the triangles move and the pins to keep the 'course' up so i does not fall down, i played it a few times and only got the ball back to the start once, the following picture is that moment.
