Rube Goldberg writing

In my Rube Goldberg I have all the six simple machines.

First my ball (wheel) goes  down a inclined plane and knocks down the dominos (lever). The last domino has a string attached to it, witch stops the ball (wheel) ,but when the domino (lever) knocks over the ball (wheel) moves and goes through a tube (ramp). Then the ball (wheel) flies into a cup and the cup starts to go down because of the weight, there is a pulley that is holding the cup and blocking the ball (wheel) from going down. So when the cup goes down the ball (wheel) goes down the screw (swirly slide) and then comes out the other end and  knocks down the dominos (lever). The last domino (lever) knock the car (wheel) and the car starts to move, after that the car (wheel)knocks a watering can and the watering can waters some flowers and the water overflows and knocks a wedge over. After that the car in front of the wedge rolls down and lands on scissors (wedge) witch cuts the balloon, finally the balloon floats up and pops! Confetti comes out and there is a party.
