Manual drill using a large dowel, flat bit of wood with a hole for the dowel and string to attach the ends to one end of the dowel with a drill bit in the other end.

Wind it up and then press down on the bar forcing the dowel to spin. Press hard enough and excess force winds it back up again so you can keep pumping it to drill.

We did cheat by using a modern drill bit but was fun demonstrating it at my elementary science fair.
