EggTimer in a NASA Drop Tower

A teacher workshop was conducted at NASA Glenn during the summer 2009. The teachers were challenged to develop a microgravity experiment that would be dropped two days later in the 2.2 Second Drop Tower.

One team brought an egg timer with sand particles that drop through a small hole. The development of this experiment turned into an exercise to design a 'contraption' that would invert the egg timer when the experiment was released into free fall. Otherwise, with the timing of the drop tower process, the egg timer sand would have all fallen to the bottom by the time the experiment was dropped.

The team developed LEGO (tm) towers with the egg timer suspended between the towers. A weight was attached at one end of the timer and a rubber band at the other end. The weight and rubber band balanced each other in the presence of gravity. In free fall, the rubber band pulled the egg timer vertical.
