Moving air can pack a powerful force, especially when Bernoulli’s Principle is involved.
The Soda Can Jump experiment uses Bernouli’s awesome principle to launch an empty soda can out of a coffee mug. It’s a hands-on experience in physics that you won’t want to miss. See Steve Spangler’s website for more details about how this works. Read more…
