Spin-Gineer - Building Set

Beam me up! Safely weld and construct bridges as big as 2' tall or any other structure you dream up. Connect plastic beams and use real-life techniques and equipment, like a welding mechanism that spins the rods rapidly to get hot and melt your structure into place. Includes over 200 plastic beam pieces that can be easily snapped together to form a whole new structure each time. Requires 4 D batteries, not included.
