Gravity Marble Game - Load the marbles onto the top......nudge one into the spoon.....watch gravity and design go to work! This is one of our cleverest toys. The weight of the marble forces the spoon to fall, until the marble rolls out into the box. Without the weight, the spoon rises, striking a release trigger, which pops another marble onto the spoon. The cycle repeats until all the marbles have landed in the box.
