It says it all. It should have only been a small fireball....whoops.
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
Ferrofluid is a magnetic liquid. It is composed of tiny nanoparticles
of magnetic material. It flows like a liquid and attracts to a
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.

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.
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.
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
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.
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?
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
