Build your own gyro robot who balances itself on the monorail track.
Discover the amazing power of gyroscopic effect with this cool monorail robot. Use the illustrated instruction manual to build this fascinating 186 piece kit, with 26 track layouts on the looping monorail track. Wabo will navigate the circuit, balancing on just a single wheel like a tightrope walker! Use the 3-way splitter and cross switch to send Wabo in different directions and even across a seesaw. Brilliant fun project - seems to defy gravity!
