Stacking plastic cups is one of the least expensive and creative toys found in every household.
Practicing eye/hand coordination, when they aren’t even two years old yet, makes a grandma proud.
Other games to play include trying to bounce ping pong balls into the cups.
In case you haven’t guessed, this is an airport terminal and the highway is edged with marbles.
My husband has had to resort to hiding some disposable cups, when planning a cookout.
The Junior Olympic Games for Championship Cup Stacking is held annually and draws more than 17,000 athletes from around the world.
