Cotton-ball Vaseline Race

Bring 2 guys and 2 girls up (or one student from each grade). Give each student a pile of cotton balls. They must move the pile to another location of your choice (could be next to them on the table or across the room in a bowl, etc.) by putting Vaseline on their noses and picking up the cotton balls with their noses. They may not use their hands. The first one to move all their cotton balls wins.
