It might be October, but that doesn't mean we can't show you one last insane inflatable object for summer fun. This thing is actually the court for a game called Bossaball, which is apparently popular in Spain. They've combined the excitement of volleyball with the potential injury of multiple people jumping on a trampoline. The entire court is inflated, and in the center there's a trampoline that'll bounce you extra high for super spikes and blocks. This isn't exactly a game you can pick up and play, as the court requires about 45 minutes of install time before it's ready for a leg-breakin' good time. It's apparently rentable for parties or events, although one would think you'd need a bit of practice before getting into any serious match. For extra fun you can get a "samba referee," basically a DJ who will say you're out of bounds. Personally, I think samba refs are ruining the dignity of Bossaball, but I guess I'm just a Bossaball purist. — Adam Frucci
