Activate the light when opening the doorWhen you open the door, you pull the pulley that moves up the seesaw. That moves the slide and the ball falls and hits the domino tiles. The last tile turns on the light.

My complex machineMy machine is used by tapping the first token with the finger. That token hits the other tokens. The tokens go through some books and then there is a marble that moves pushed by a token. In the end, all the tokens fall.This machine is useful to press a button which it is far, or you can make a funny video because is like a butterfly effect.Rubén 4ºA

My machine is a manual water dispenser.To operate it and serve you water, you justhave to turn the cap and see how much wateryou want, it is very easy to use!
