Austin Bubble Soccer
Bubble soccer is like playing soccer inside of a human hamster ball
The website describes it as a mix between soccer and bumper cars. You wear an inflatable bubble that covers everything above the knees. Average price is about $20 per person per hour, and if you can't find people to play with you can always check their meetup page to see if there's any group you can join. You must be at least 7 years old. As for the location, there are a few places that they like to frequent, but they're willing to travel outside of Austin/Round Rock for an extra fee.
