One child pours feed corn down the tube. Another child is blocking the corn at the bottom with a little pink cup that fits nicely over the bottom of the tube. At this point, the tube is pretty full. The child at the bottom checks the to see how full the tube is. He decides it is full enough, so he pulls the plug and the corn whooshes down the tube. Another child takes his place with a little yellow pail to catch the corn sliding down the tube. Almost simultaneously, another child starts drumming on the tube with his spoon.
