A gumball vending machine is a mechanical device that dispenses small spherical balls of chewing gum. These machines are typically made of metal and glass, and can be found in a wide variety of locations such as shopping malls, grocery stores, and arcades.

The machine typically consists of a clear glass globe that is filled with gumballs of various colors and flavors. The gumballs are loaded into a spiral track that leads to a dispensing mechanism. When a customer inserts a coin into the machine and turns the handle, the mechanism releases a single gumball into a chute where the customer can retrieve it.

Gumball vending machines are often used as a fun and affordable way for customers to satisfy their sweet tooth cravings. They come in a variety of shapes and sizes, with some featuring intricate designs and themes to appeal to specific audiences.

While gumball vending machines may seem simple in design, they have been a popular fixture in the vending industry for decades and continue to bring joy and excitement to customers of all ages.
