egg beaters

This is a video of gingerbread dough that some of my friends and I made during winter break. As you can see, these egg beaters have uniform circular motion! They are following a circular path at a constant velocity. As we all know, uniform circular motion means that there is a net force directed radially inward of magnitude (mv^2)/r. This net force is strong enough to mix all the molasses, flour, and butter together. You can increase the velocity of the egg beaters by changing the setting on them. When you first start mixing the ingredients, the flour is very heavy and thick, so it takes more force to mix it together. Electric current from an outlet supplies the force necessary to turn the egg beaters. When you are finished mixing the ingredients, you can get some of the sticky dough off of the egg beaters by increasing the velocity. You have to be careful not to lift the beaters too far out of the bowl, otherwise the dough will fly all over the place!
