Went to the Ringling Bros. show on Saturday with my oldest daugher (9 yrs). We had a blast. Hardly any juggling at the show, but the graphic design was great. I enjoyed the all black-and-white costumes in the show opening.
There were a lot of height-oriented, heart-stopping bits....some antics at the top of a sway pole and the show climax, a wheel of death.
The sway pole act involves climbing to the top of a long flexible pole. At the top is an apparatus for holding on, and then you make the pole sway. I have to stop there, I might faint. Here's a photo of a sway pole.
The show was heavily aimed at the young, I'd say, except for the danger acts. I doubt the kids got the heart-stopping thing. But after you pay $12 for some cotton candy, your heart is already in danger. :)
