Solid Nitrogen, Vacuum Cooling and Dry Ice
What happe when you decrease the pressure around a liquid? It boils. Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature of t...

Effects of water pressure
This clip illustrates the effects of water pressure on a ball filled with air. The same compression happe to the air iide the human ear, which is why we have to equalize the ea when freediving....

Heat conduction
Heat conduction. Wooden and metal pedestal stand in hot water. Since metal is a better heat conductor than wood, the ice cube on a metal pedestal melt faster than the ice cube on wooden pedestal....

Paramagnetism of Oxygen
Oxygen gas is condeed into liquid form and then poured between the poles of a strong magnet so we can observe its paramagnetic properties.We send O2 gas through a copper coil, which is then imm...

Lenses and Vortices
NASA Astronaut Don Pettit takes advantage of the weightless environment aboard the ISS to do diffusion and le experiments with pure water. Distributed as part of a collaboration between NASA and...

Anti-Gravity Water Trick
It's easy to keep water in an upside down container with nothing but a card. However, only those possessing extreme skill can keep the water from falling out when the card is removed. Are YOU skil...

Superfluids
Strange quantum fluids that love to sneak out of cups have been found trapped iide the core of a dead neutron star.Fb6zWYCYGfE

Air Pressure and Altitude
Join Dr. Al Hacen and explore the correlation between Air Pressure and Altitude.7_yf-iRf8Vc

Strobe light makes water drops fall in slow motion
Using a reciprocating pump and a strobe light, we can make water drops appear to fall down (or up) in slow motion. This illusion is due to the periodic nature of the pump: each droplet forced out...

Fun with Antibubbles
Astronaut and chemist Dr. Don Pettit does physics demos that are out of this world. Currently on board the International Space Station, Dr. Pettit presents fantastic physics that can only be demo...

Why do some things float?
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. Fa of David Letterman are quick to p...

How A Wing Actually Works
Lift is an important concept, not only in flying but also in sailing. This week I'm talking to Olympic Sailor, Hunter Lowden. But before I get to the physics of sailing I thought I would explain l...

Absolute Zero: Absolute Awesome
