USB Charging When shaken, the propeller operates and it floats around the room. You can play with it by using the sensor on your palm to make it float in various ways. It descends when it touches the ceiling. It has been opened once to check its operation. I bought three for my grandchild, but he seems to like the blue one, so I'm selling this one. Adults can enjoy it too. There is no remote control. Please play with it indoors. Be careful, as it will fly away if you take it outside. #EasyFutureToy #Hovering #Drone
