Can they really balance like that?

Yes. I take one of these and a string wherever I run programs because the kids go crazy over it. It really holds their attention. Even young kids can make it move quite fast just by raising or lowering one end of the string. Despite the appearance of 3 acrobats towering high on a bicycle, most of the weight is below the string in the end weights. As long as they're gentle, it balances itself. If the tightrope acrobats pique the kids to start thinking about what balance really is, and to become aware of what "center of gravity" means, they've done their job.
