Get a volunteer.
Find a volunteer willing to get soaked for a good cause. Students and staff alike will love the opportunity to throw wet sponges at their favorite teacher or principal!
Sell your tickets!
Sell students (and staff) tickets for the opportunity to throw a wet sponge at the designated volunteer. The more prestigious, the more incentive!
Pick a warm sunny day and have fun throwing! Be sure to talk about the contract between having no water to drink, and having enough water to use for play.
