Step 1: Step 1: the Dominoes
We set up the dominoes on top of the stand to fall off and hit the hook on the string. The hook is hanging on the string between two knots.
Step 2: Step 2: the Hook
After hitting the hook with the domino it will fall down the string and hit a golf ball in the pipe. The golf ball is set up at the end of the pipe so that the hook will be able to hit it easily.
Step 3: Step 3: the Golf Ball
When the hook hits the golf ball it moves down the pipe. (When setting up the pipe put something under it to prop it up to add some incline). When the ball gets to the end of the pipe, it will hit a Wiffle ball.
Step 4: Step 4: the Wiffle Ball
The Wiffle ball is set up at the end of the pipe. We put it there so that when the golf ball gets to the end of the pipe it will hit it off the table and pull the string with the clothes pin on the end.
Step 5: Step 5: the Clothes Pin/Funnel
We placed the clothes pin on the end of the string under the funnel. When the string is pulled by the falling ball, the clothes pin will move out from under the funnel and allow the balls inside to fall down through the hole of the cabinet. The funnel is placed between books to allow stability.
Step 6: Step 6: the Funnel and Track
Under the cabinet we set up a funnel and track attached to it to allow the balls to move down through the cabinet and hit a plastic wheel set up at the end of the track. When the balls fall through they hit the wheel pushing it off the cabinet drawer.
Step 7: Step 7: the Wheel Pulling the String
We set the wheel on the end of the track close to the end of the shelf in the cabinet. When the balls hit the wheel it will fall off the track pulling the string attached to the leggo block. There are two leggo blocks at the end of each side of the track piece. The leggo block will be pulled off the table due to the pulling of the string. The track will decline causing the toy car to fall down the track.
Step 8: Step 8: the Car
The car is set up at the top of the track and will get pulled down. When it hits the bottom, there is a container of water at the end of the track. The car will fall into the boat set up at the end of the track in the container.
Step 9: Step 9: the Boat
When the car falls in the boat, the boat will be pushed to the end of the container where there are dominoes set up. The boat will knock over the dominoes.
Step 10: Step 10: the Dominoes and the Leggo Block
After the boat moves across the water it will hit dominoes set up at the other end of the container. When the dominoes are done falling, they will hit a leggo block set up on the ledge of the counter.
Step 11: Step 11: the Cork and Funnel-Final Step
When the leggo block falls off it will pull the string attached to the cork. The cork is holding cereal in the funnel. When the string falls out, the cereal will fall into a bowl placed under the funnel. The funnel is held up on the cabinet by a clamp. That is the final step.
