    Our Step List

    1. Flip the two switches to trigger the electricity flow.
    2. This is transferred to a fan, which spins thread, which is attached to a needle, which is attached to a tire. This releases the needle.
    3. Once the needle is released, the tire is free to roll down a track.
    4. The tire hits a pot, which falls off of the table. The pot is attached to a string pulley.
    5. The string pulls an upright-standing stick down.
    6. Now, the zip line is free to glide down the string.
    7. The zip line carries a cart which carries a marble. The zip line swoops over a tube and the marble in the cart enters this tube.
    8. The marble travels through the tube and down the track and into a medicine container.
    9. The container is connected by string to a small box. Behind this box is a marble on an elevated track. When the container is hit, the box is pulled off the track, allowing the marble to roll down.
    10. The marble rolls down the track to a hit a smaller ball.
    11. The smaller ball goes down a funnel and into a connecting tube, and rolls into a stick and knocks it over.
    12. This stick is attached to another stick. This stick falls down too. A tube is above this stick, and water is able to flow through it once the stick is knocked down.
    13. The water piles into a lighter, elevated bucket. When the weight of this bucket causes it to decline, the other bucket will rise.
    14. This bucket is attached to a stick. This stick will topple over because it’s attached to the rising bucket.
    15. On top of this stick is a hammer. When the stick falls away, the hammer is released and nails in the nail!
