I was given a couple of tickets to The Aluminum Show. It's an Israeli dance troupe that does all kinds of crazy stuff with flexible ducts and streamers and inflated metallic balloons. Very athletic, very loud and flashy (literally the strobe lights were a little intense at times) and quite fun.
The audience participation segments were entertaining and wild. I snuck a photo of the giant pillows that were flung out to be bounced around.
There were lots of kids there, and it seemed like they were having a blast. The Aluminum Show is touring all over the place, so you should try to see them if you can. Get seats in the orchestra section if you want full-on participation. I would pay for that, now that I know.
