House of Air, San Francisco, you will love the uniqueness of the place. Everything about it is cool. It's basically a warehouse outfitted with trampolines. It's is set up with some sort of special harness jump trampoline, the cool stuff. There is an inflatable jumper in the corner for small kids. A dodge ball arena, with soft balls of course. And occupying the most space, the skate board park like trampoline area. You start off by going into a cashier area and then you get a bracelet denoting your time limit. The house of air is booked on hours, not all day type of reservation. Usually, you will go to the big trampoline in the back but eventually you'll notice the great dodge ball arena. The dodge ball arena is filled with 20 balls and the entire arena is outfitted with trampolines, even the walls. You will be bouncing off the walls while getting pelted before you know. The dodge ball area was the best in my opinion. While the large trampoline area does have a projector showing some "extreme sports" videos, it just gets a bit boring. Unlike dodge ball, where you be diving and throwing balls in no time. One great problem you will find yourself facing is being unbelievable sweaty and thirsty. They have conveniently placed a restroom and water fountain near the entrances. A great plus is that the water fountain is actually mechanically cooled not the awful pipe-temperature water every fountain has. The house of air is expensive but a unique experience and defiantly a place to visit.
