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
