Bowls made of confetti! Great recycling art project--save all those leftover paper scraps (put in small bowls at each table). Collect a bunch and have the kids cut them up; Then make bowls made from confetti.
Positive Charge- Use an old toolbox (or any container) as an undercover charging station. Drill a hole in the back of the box to make way for a power strip. Then cover the power strip with a board featuring drilled holes for electronic cords.
