Kites are overrated. Even when they work, which is to say when they’re not accidentally wrapped around a powerline and posing an electrocution hazard, they’re sort of boring. Here’s a better idea: the PowerUp 3.0. A ridiculously light carbon fiber propeller and rudder powered by a small microchip, the PowerUp 3.0 syncs to a flight simulator smartphone app via Bluetooth. Slide it on to a cleverly folded piece of printer paper and – boom! – remote control airplane. For $50, PowerUp 3.0 can help teach your kids about aerodynamics, engineering, and how to one-up every other kid on the playground. More importantly, it will teach them that you are a master of the sky.
