During Spirit week at our school we had a lunchtime activity entitled “Polar Bear Tough Man” we had brave students get in a kiddie’s pool (or if you have a large enough body of water around) full of ice water and the person that stayed in the longest won. It was a little dangerous because it was so cold outside but if you live in a warm climate then go for it! The prize was a mug of hot chocolate for each participant and a t-shirt for the bravest participant.
