Bad dancers are like a cross between a drunk octopus and a malfunctioning robot trying to climb and invisible ladder. Their moves are so clumsy and awkward, you’d think they were auditioning for a new reality show called “So You Think You Can Dance?”. But how can you become a better dancer if you’re too shy about your appalling skills that you’re afraid to try? That’s where the Silly Sack comes in! It’s a dancing sack that’s made from a very stretchy fabric that won’t hinder movement whatsoever and come in a range of colors and even kids’ sizes too so they can join the fun. Now you can practice dancing and remain completely anonymous.
