Who needs batteries when you've got kid power? Two-year-old Max Bratman was spotted harnessing his kid energy to power a new PlasmaCar ($54) through a Santa Monica park yesterday. The pedal and battery-free toy uses natural forces, like inertia and friction, to wheel tots along flat surfaces, while lil ones can steer the ride-on toy to their desired destination. Outfitted in a FreeCity Youngones hoodie, Christina Aguilera's soon-to-be birthday boy spent the afternoon riding with his dad and a pal.
