Popcorn (1976)

"A dexterity game in which a domed center containing 4 colors of marbles is then automated with 2 D cell batteries to begin to "pop" and move. On each of 4 sides of the dome is a row of slots for each player and colored to match each of the balls or popcorn; blue, green, white and red. In front of each slot is a button and if pressed will push out the popcorn that falls into the slot if it is not a matching color. Each slot can hold up to two balls and the goal is to get as many of your matching color as possible. 2 "D" cell batteries are required for popcorn effect to work. "
