Balancing Pterosaur, a STEAM toy from Tedco Toys. Learn about physics, think creatively and experience interactive play. "Hidden at the end of each wing is a small weight. Working together, these weights move the centre of gravity below the beak of the Pterosaur. When you place the beak on a pivot point, the new centre of gravity will allow it to balance on the tip, spin around and sway, without falling off." For 5 yrs +
