Making a ping pong ramp
This week I made a ping pong ramp for science with Vanessa on a Wednesday
I learnt that when you make the ping pong ramp go onto the carpet to finish, it has to be in the perfect position or else it won't work properly.
This is because the tension on the carpet is rough so the ball won't go as fast.
I wonder what would happen if we tried to make the ball go up instead of down.
