Pressure & Fluids

Boyle, Charles and Cans... Oh, How I love the pressure!

You may have tried the can crushing pressure demo, you may have even tried it with a 55 gallon drum, but have you tried an entire tanker truck? In the December CoolStuff Newsletter...

Vortex Rings in nature and your physics classroom!

Posted on December 12, 2011 by Buzz Putnam

If you are looking for something that occurs in nature and is tied to the physics classroom, look no further than vortex rings. These Vortex Rings are more common and widespread in nature than most people had probably thought; in fact they are studied in great detail by aeronautical engineers and combustion scientists. But we just think they are cool!

Can a Helium Balloon Defy Physics?

Posted on December 12, 2011 by Dr. Joel Bryan

Watch this cool video and it almost seems like this balloon’s actions are counter-intuitive to everything we know about motion and inertia. Let Professor Joel Bryan from Ball State University explain what is really going on.

Duke students find a way to walk on water... Well, not quite.

Posted on April 1, 2011 by Arbor Scientific

The students of Duke University filled a pool with a mix of cornstarch and water to create a non-Newtonian fluid known as"oobleck". When stress is applied to the liquid it exhibits properties of a solid. Watch as they walk, run and jump on this amazing fluid!

As the YouTube video below shows, stopping or even slowing [...]

Fluid Mechanics

Posted on March 1, 2007 by Chris Chiaverina

Unlike solids, fluids have no definite form but instead assume the shape of their containers. Fluids include all liquids and gases and a rather strange state of matter called plasma, an ionized gas that scientists believe accounts for 99% of the matter in the visible universe.

Chemistry: Gas Laws Smorgasborg

Posted on April 1, 2003 by Chris Chiaverina

One of the challenges of teaching chemistry is making the invisible world seem real and relevant to our students. Labs present the best opportunity to demonstrate this, but too often we, out of necessity, begin each lab with a litany of “don’ts.”

The Best Physics Demos: 2002 NSTA National

Posted on April 1, 2002 by Arbor Scientific

In the Spring of 2002, Paul Hewitt and Chris Chiaverina teamed up to present one of the most memorable sessions in a long time; The Best Physics Demo Show. Paul Hewitt is the Author of Conceptual Physics and Conceptual Physical Science. Chris Chiaverina is former President of the American Association of Physics Teachers and co-author of Light Science.
