GraviTrax C Extension Interaction add-on with electronic parts that transmit and receive signals. The signal is given immediately when the bullet spins through the firing part. The player decides which part reacts to the signal: switch, dome launch site or catapult. By using the control, one can influence the movement of the bullet. The electronic elevator automatically lifts the balls one level up without manual adjustment. In this way, new kinetic energy is added, and the balls can spin almost endlessly. This STEM [science, technology, engineering and math] system teaches children about gravity, magnetism and kinetic energy in a fun way.
