#3    Gumball Machine

Why I built this:

​

To give a nice present to my sister for her birthday. It's fun and larger than she is.

Check out my video!

How it works:

First, you turn the crank to the right. While this is happening, a gumball is forced to go into a pocket in a wheel. Then a gumball pops out of the hole and rides on the roller coaster track down into the bottom holder. Then you have your gumball! It's as easy as that!

What is cool about it:

It's taller than she is!

Materials I used:

  • Cardboard

  • Hot Glue

  • Tape

  • Gumballs

  • Scissors

  • tupperware container
