Going for a Moon Walk

There is no place on Earth where you jump great heights like an astronaut walking on the moon, but you can do a version of the famous gravity moon experiment in 1971 when astronauts dropped a feather and a hammer on the moon to prove both fell at the same rate. If that is true, why don't they fall at the same rate on the Earth? Materials: 2 small umbrellas of the same size and weight. Process: Have residents feel both and compare weights. Next open one, keep one closed and have residents watch you drop both at the same time, one from each hand, onto the floor. Which one landed first? Result: Gravity is pulling the same on each, but the open umbrella is fighting the air resistance so it lands a bit later than the closed umbrella. Close both and re-drop and the result will be both landing at the exact same time. The moon experiment worked because of the lack of air to create resistance on the feather.
