If you’re looking for fun party ideas for the summer, you might want to take a leaf out of the Canyon Lake, Calif., community’s book and host your very own Cardboard Boat Challenge. According to The Friday Flyer, this one-of-a-kind day on the water has kids and adults alike fashioning vessels out of cardboard and duct tape for a race through a course set up on the water. The boat to make it back to the shore still afloat takes first prize. Held on the town’s annual Fiesta Day, the locals enjoy seeing an immense range of creativity among the cardboard boats. Last year, this ranged from a mini pontoon boat to a pirate ship, a Viking ship, and a trimaran. Some of the boaters dress up in fun costumes as well and christening their vessels with silly names such as “S.S. Sinks-a-Lot.”

For the community at Canyon Lake, the fun begins on May 23 over memorial weekend and the winners take home cash prizes for proving their seaworthiness. Houseboaters casting around for fun and unique ways to goof off in the summer should try this out and host their own cardboard boat races. It’s sure to be a blast.
