“A drop can bounce”

November 11, 2009 @ 6:53 am | Filed under: Fun Learning Stuff, Science

The everyday magic of surface tension: “the quality of a liquid that causes the surface layer of that liquid to behave like an elastic sheet.”

HT to my hubby, as usual. He always finds the best stuff.

  1. Wow. Very cool!

  2. I’m not super-sciency, but it seems this could change a lot in the physics world.

    What’s most amazing to me is that the last little drop (at the end of the clip) didn’t even cause a ripple as it bounced. Wow.

  3. . . .this begs the question: what is the surface tension of a cupcake? Why does the cupcake behave like an elastic sheet calling forth repeat bounce-backs? And more importantly can that ingredient be removed without diminishing the taste?

  4. Amazing! Thank you for sharing!

  5. Wow, who knew?

  6. Really cool. I’ll definitely have to show my 6yo. It reminds me of an experiment we did this week about antibubbles (water surrounded by a thin film of air rather than air surrounded by a thin film of water). There’s a cool video at the site: http://www.thenakedscientists.com/HTML/content/kitchenscience/exp/bubbles-that-sink-antibubbles/

  7. Very nifty. Know what we’ll be doing for science next time . . .
