Have businesses in your area donate styrofoam packing peanuts. Then borrow kids’ plastic pools from students’ families. Fill the pools with the peanuts. Next, obtain as many plastic eggs as you have children participating in Field Day. Place a “Field Day: Where Everyone Is A Winner!” or “Field Day! Fun • Fitness • Health” Temporary Tattoo in each egg. Then hide the eggs in the pools. Let everyone dig in and find an egg.
