Bouncing a Drop of Water on Water

Alex

Here's a nifty party trick, courtesy of physics: how to bounce droplets of water on the surface of water.

Physics Buzz Blog explains:

Typically, when a droplet of water plunges into a pool of water, it will bounce slightly and then coalesce with the rest of the water. But there's a way to keep the bounce going indefinitely.

If you put the pool of water on top of a loud speaker, you can vibrate the surface. This vibration can cause water droplets to continuously bounce and levitate atop the liquid surface.

Physicists Pablo Cabrera-Garcia and Roberto Zenit from National Autonomous University of Mexico conducted the experiments and filmed them with a high-speed camera for your viewing pleasure.

Sriracha is good on almost anything, in my opinion. Seems like everything is in garlic or cheese at least 50 times over (yes I'm exaggerating, kinda). Sooo boring.
A hot tasty chip? Oh yeah, ill try it. Hopefully they don't sissify it as sriracha is supposed to be hot!
I would also vote for chicken and waffles because its different.

Any flavor you like is good on a potato chip. But the delivery method is where I differ with my kids. I'm old school. I like to buy plain potato chips and dip them into real flavors. The rest of the family is just as happy with the flavor dusted on top. I could never get into cheese powder or barbecue powder -give me the real sauce!
