I had a bunch of fun at Maker Faire NYC! I saw a lot of really neat builds, tools, workshops and displays, but the rubber band whip really stood out as something easy and fun anybody can do. Maybe im still a 12 year old at heart but I think this thing is a blast. And it breaks the sound barrier WITH RUBBER BANDS!
