Float or Sink - Cool Science Experiment

Scientists seem to be infatuated with objects that float and sink. Even non-scientists find great joy in dropping stuff in water to see if it floats or sinks. Fans of David Letterman are quick to point out one of Dave's favorite segments called, "Will It Float?" Here's the latest float or sink challenge: Why do lemons float in water but limes sink? Think you know the answer? Not so fast...

About Steve Spangler Science...




Additional Information:

On the education side, Spangler started his career as a science teacher in the Cherry Creek School district for 12 years. Today, Steve travels extensively training teachers in ways to make learning more engaging and fun. His hands-on science boot camps and summer institutes for teachers inspire and teach teachers how to prepare a new generation for an ever-changing work force. Over the last 15 years, he has also made more than 500 television appearances as an authority on hands-on science and inquiry-based learning.




His recent appearances on the Ellen DeGeneres Show have taught viewers how to blow up their food, shock their friends, create mountains of foam, play on a bed of nails, vanish in a cloud of smoke and how to turn 2,500 boxes of cornstarch and a garden hose into a swimming pool of fun.

[anooshiravanensafian]

sir thank you for your helpful video but i have 3 questions
1- When is the pontoon is naturally stable ?
2- Two ways to improve the apparatus reading are ?
3- What will happen if we change the density of the fluid, using brine, say, instead of fresh water ?

I can't go to sleep there are too many cool science videos!!!

[poolmanishere]

I love this kind of stuff! When I was younger I used to watch "Mr. Wizard" all the time. Thanks for all the videos.

[drea]

hahaha, the advertisement is super funny!!
