Surprisingly, foam parties aren’t nearly as slippery as you might expect. The foam is made up of dense bubbles with minimal water, so it doesn’t leave behind a slick film. Surface type does make a difference—concrete, asphalt, and rubber surfaces provide the best traction, while grass can be slightly more slick.

We don’t recommend dirt areas since they can turn muddy, and we’re unable to set up on high-gloss surfaces like marble or freshly sealed floors for safety reasons.
