Elkhart, Ind. It was a chance to jump in the pool, and learn a few things about staying safe in the water.
Plus, take part in the world's largest swimming lesson.
Over 50 kids at the Shepard Swim School, joined thousands around the world in the record breaking attempt at the world's largest swim lesson.
And the kids say they were excited for their chance to make it into the Guinness Book of World Records.
Lucas Klopfenstein, 11, was excited to be participating.
“I'm like yes, I'm going to finally be in the Guinness Book of World Records because at school I check out all the books and I look through them and I try to find something that I'm good at and this is a chance, so it was really fun,” he said.
The lesson still has to be approved by Guinness before becoming an official world record.
Research shows if a child doesn't learn to swim before third grade, they likely never will.
