As a kid, did you ever take apart a toy you loved, only to discover you couldn’t put it back together? In this video, uBreakiFix does exactly this with Sphero’s BB-8, the latest toy released from the Star Wars franchise to hype up Star Wars: The Force Awakens. BB-8 is a toy droid that can be controlled from your smartphone with an app; you can move it with your phone. Though many were excited about the toy’s release, not everybody understands how it works. The video below shows the full mechanism of the toy, doing so by taking BB-8 apart with a rotary tool. Sorry, BB.
