Ping Pong Pressure – Sick Science! #151

(0)

We have all experienced wind and, like it or hate it, it affects us. Moving air can jostle your hair about, fly a kit, or, in extreme cases, tear entire buildings from their foundation. Did you know that this moving air actually creates low pressure, though? It’s true. On an exceptionally windy day, you can even see tall buildings bowing towards each other near their tops! We’re going to recreate this phenomenon using ping pong balls in the Ping Pong Pressure experiment. – See more at: http://www.stevespanglerscience.com/lab/experiments/ping-pong-pressure#sthash.HINuLOio.dpuf

  1.  The fast moving air between the ping pong balls creates a low pressure area. The (relatively) higher pressure air on the outside of the ping pong balls push them together. This is similar to how an airplane wing creates lift

  2. Because a ball like this is designet to spin when it hits air and hence making ping pong unpredictable, so when air hits it its actually trying to spin and it usually spins the same way air is hitting, thats why
