Science Videos for Durham Deifell's 8th Birthday 2020

On May 6, 2020, Durham Oakes Deifell turned 8. This sadly occurred during the corona virus pandemic and very much limited his options for celebrating. His mother requested videos; below are several by Mel and Pat Oakes, his grandparents, which reflect his current interest in science. Included also are three nostalgic videos.

These videos introduce evidence for the atmosphere around us and the pressure it exerts on all bodies exposed to it. At sea level every square inch has approximately 15 lbs of force! This is just the weight of the atmosphere above, distributed over the area below. Similarly, the water pressure at any depth in a swimmng pool is the weight of the all the pool water above you divided by the area (length times width) of the pool. Here are a couple of numbers to remember: a cubic ft of water weighs 62.3 lbs. A cubic ft of air weights .08 lbs ( 8 sheets of paper). Remember our atmosphere is many times taller than our pool is deep. The atmosphere is about 39,000 ft (not uniform however), your pool is about 6 ft.
