Inside a Cow's Stomach

Cow's are sometimes fistulated for research purposes - what results is pretty hard to "stomach"!

Composition Reaction Aluminum and Bromine

A composition reaction involves combining two different elements to make a compound. In this case, we get to observe the exciting and violent combination of aluminum and bromine, which is decidedly exothermic.

Potassium Permanganate Fountain

Potassium permanganate is a very interesting substance, interacting in fascinating ways with many different substances. In this demonstration, potassium permanganate reacts in a most beautiful way.

Synthesis of Iron Oxide

It's interesting to see steel wool burn, but even more interesting to note the increase in mass in the reaction product.

Sulphur Burns in Oxygen

This video proves that one must take extreme care when working around flammables. Are you certain that you are not carrying any static electric charge?

Here is a very novel way to demonstrate a change of state. By filling a ping pong ball that has slots in it with liquid nitrogen, the ping pong ball can be made to spin rapidly.

This particular video has a magnificent close up of the sodium-water reaction that clearly shows the ignition of the hydrogen gas that is produced.

Sulphur hexafluoride is a gas that is 6 times more dense than air. As a result, it can readily be "poured" into tanks and containers. As the video clearly shows, objects made of aluminum foil can float on the gas.

The ethanol "jug-jet" demonstration can be an effective way to show rapid combustion. But in this case, that combustion is a bit too rapid!

Composition Reaction: Potassium and Bromine

This is an interesting simple composition reaction, because it is quite explosive.

Faraday Cage

This video is very effective at demonstrating the Faraday cage. The man inside the cage in this video is completely safe, even with 100, 000 volts applied.

The Danger of Static Electricity While Refueling

This video proves that one must take extreme care when working around flammables. Are you certain that you are not carrying any static electric charge?

When light passes through slits and is directed to a screen, it produces an intereference pattern, due to constructive and destructive interference of waveforms. Can we try this experiment with electrons?

Superconductivity - Meissner Effect - Magnet Levitates

Supercondutors don't allow magnetic fields to penetrate, so a magnet placed on top of superconductor will levitate.

Plasma Ball

Plasma is the highly energetic fourth state of matter, the problem is however, we don't get to see it very often... unless you have a plasma ball!

Carbon Nanotubes Used to Grow Bone

Carbon nanotubes are one of the strongest and stiffest materials known, so many applications for these nanotbues have focussed on engineering. But what about medicine? It turns out that nanotubes may be an excellent support material for growing bones cells.
