The DigiWiz Cool Monster Laser Gun is a huge hit with all ages. This STEM Kit works using gears, motor, infrared light.
The gun is equipped with an infrared light to point at the bull's-eye, when the bulls eye is hit the monster starts struggling. The noise made by the gear motor sounds like whine of the monster.
