A three stage fountain pen delivery system. The tower tilts and lays nearly flat. The tracktor moves the launch pad back for forth. There are three led lights for appearance. Three battery compartments are built in. One is 9 v, other is 4.5 v and the last is 3 v. the pen is 24 g plate fountain pen modified . Magnets hold it straight in the launch tower. There is a mini level to show the action on the tilt Compound levers run off a mini motor located in the base. It would take a mini engineer to figure out how to change the batteries. There is a video showing the tilt and trator action if you would like to see it, let me know
