New HD Chemistry Demonstrations

Enormous Fireball
It says it all. It should have only been a small fireball....whoops.
Levitating Bubbles
This simple but amazing video explains how everyday bubbles can float on a magic layer of air. It all has to do with density of air and some dry ice. 
Amazing Ferrofluid
Ferrofluid is a magnetic liquid. It is composed of tiny nanoparticles of magnetic material. It flows like a liquid and attracts to a magnet.
Solid Rocket Fuel Ignition

Once used as solid rocket fuel, because the reaction requires no oxygen. Sulfur and zinc react vigorously. The reaction with zinc produces flame and a near explosion. Sparks fly and smoke billows in this dramatic chemical demonstration. Please do not try

The Great Soda Experiment

Ever wonder how much sugar is in your soda? This simple experiment that anyone can do puts Coke and Diet Coke head to head in a density test.

NonBurning Money
A 20$ bill is dipped into a solution of water and isopropyl alcohol. It is then ignited and the bill bursts into flames but the bill does not actually burn.....well most of it anyway.
Vacuum Chamber Project #3 Inflating a Balloon

A partially filled balloon is placed into a vacuum chamber. When the vacuum is turned on the pressure exerted on the balloon decreases and the balloon can expand until the bell jar is completely filled. When the air is allowed back in the jar, the pressure is reestablished and the balloon returns to its original volume. This is a great example of Boyle's Law which shows an indirect relationship between pressure and volume. 

Levitron Physics
The Levitron spins and surfs on magnetic waves! Pass your hand above, underneath, and around the top. It will continue to spin and float only touching air! The LEVITRON floats free in space, supported only by the repelling magnetic force produced by permanent magnets.
A Broken Heart for Valentine's Day

Watch my heart get broken just in time for Valentines Day. A marshmallow filled chocolate heart is placed into a vacuum and allowed to expand. Then I let my heart get crushed when the air is let back in. Kind of like what happens in life.


Supersaturated Solution Alternative Demonstration

The "Hot Ice" reaction is amazing but messy and can only be used once. A great reusable alternative of a supersaturated solution are chemical hot packs that you can buy from a camping store. They contain a solution of sodium acetate that can be reset in less than an hour. They are also good as hand warmers, but why would you buy those?

Mallomars Transformers

When Mallomars are placed into a vacuum they go through a cool transformation. The marshmallow inside expands and breaks thought the chocolate coating. Interestingly, when the pressure is reapplied the mallomars go back to its original cookie shape.
