Our Step List
Edison’s Innovative Inventors:
Zip Gary’s Zipper
Step 1: Water is poured into a recycled soup-can-pulley-system. The water-filled can sinks as its counterpart rises.
Step 2: The empty soup can acts as a wedge by bumping a modified tube, which teeter totters a marble. In our parts of town, we call that “cherry bombing.”
Step 3: The lonely marble enters into a green funnel...also recycled from an old auto body shop.
Step 4: Then traveling through a white tube, gains speed.
Step 5: Using a recycled 2-Liter bottle, the same marble travels into the opening at the top.
Step 6: A cereal box was transformed into a spiral screw and the marble makes its way to an incline plane.
Step 7: The marble pushes the car down the incline plane which was donated by Igus.
Step 8: The car bumps into dominoes and they fall down in a linear pattern.
Step 9: The dominoes trip a mousetrap that has a Popsicle stick attached.
Step 10: The wood taps on a recycled toy, sending it into a spiral whirl.
Step 11: The whirl knocks a book, which is standing upright
Step 12: The weight of the tipped book knocks into the weight of the pulley system.
Step 13: The weight falls down and the pulley lifts up on the hook attached to the zipper, zipping Gary’s zipper…
Awe… “That was breezy!”
