This awesome vending machine has four main interactive segments: First, you insert coins (quarters, dimes, nickels, and pennies) into the slot at the top and turn a knob to sort the coins. Then, the coins fall into an interactive coin track area where they slide down ramps, make jumps, and ring bells. Next, the coins fall into a device that allows you to make your “purchase” with the push of a button. Finally, your prize pops out of the machine, and the coin falls into the bank, sorted into neat stacks by denomination.

Explore lessons in physics, math, and mechanical engineering as you build and play with the vending machine. Learn about gears and other simple machines, gravity, forces, motion, and collisions. Try some simple math lessons related to the coins and money.
