The Design Your Own Gumball Machine Kit offers an engaging STEM experience that combines fun and education. Children can construct their own gumball machine and observe gumballs performing tricks with a turn of the crank, all while learning about mechanical physics. The kit encourages trial-and-error experiments, teaching problem-solving and engineering concepts in a hands-on way. It includes a full-color, easy-to-follow guidebook loaded with content to assist in the building process. The kit fits standard machine-size, 16-mm (5/8-inch) gumballs, and a small supply is included to get started.
