Tired of feeling like you need to purchase carbon offsets to make up for your Slinky’s environmental cost of production? Yeah me too. Finally there’s a product that will make you feel good about the earth and walk down stairs like an elongated spring- it’s Flexy, a cardboard Slinky. Made of recycled, biodegradable materials, the Flexy can do all of the exciting things a Slinky can do like fling, sunrise, high fall, big dipper, rainbow, rippling rainbow, hand walk / stair walk and sculpture. If you know what all of those moves are, you’re complete Slinky nerd. $18 for this cardboard toy, fun Slinky theme song not included.
