5B30.20 - Zeppelin
Charge the Zeppelin with the charging rod and then with the two small paddles show that the charge density at the pointed end is different than the charge density on the rounded end. The paddles to use have metal on one side and plastic or leather on the other side. The leather or plastic side is the one to use for this experiment.
