#10 Plasma From Grapes 

You have seen a match make plasma in the microwave. You have seen a compact disc light up. Now you are going to see why it is dangerous to put grapes in the microwave.

 

#9 Marshmallow Man in a Vacuum
This amazing video demonstrates what would happen to a marshmallow man in space. Since space is a vacuum the air inside the marshmallows expands due to the absence of air. Watch how big this guy gets.
 
#8 Liquid Nitrogen Rocket
Liquid nitrogen explodes a soda bottle in just a few seconds. Enough to send a bucket a few hundred feet into the air.

#7 Contact Explosive

If you like explosions, explosives, dry ice bombs, chlorine bombs blowing up your about to be amazed from this simple compound. Just blowing on it causes it to explode. Pretty cool.
 
 

 

#6 Thermite

The term 'Thermite' refers to the mixture of aluminum and ferric oxide used in this experiment. It is sold commercially and is used for such applications as railroad welding and incendiary bombs. Rust and aluminum are combined and ignited with a magnesium ribbon. Molten iron is produced and lots of energy is released. This demonstration produces heat at above 2800F or 1500C. Fe2O3 + 2 Al --> Al2O3 + 2 Fe Safety-This is an extremely DANGEROUS reaction and should only be done by trained professionals. Since YOU are not a trained professional DON'T try it.
 
 

#5 Instant Freezing
A seed crystal is dropped into an unstable supersaturated solution of sodium acetate NaC2H3O2 and it completely crystallized in front of your eyes. This chemistry more demonstration is prepared by heating 700 grams of sodium acetate in 50mL of water in a flask until all the solid dissolves. The solution is then cooled back to room temperature. Drop a seed crystal and see the very cool results.
 
#4 Sodium and Potassium Exploding in Water
All the alkali metals react with water to produce elementary hydrogen and the corresponding alkali hydroxides. The reactivity increases with increasing periodic number. The reactions
2 Na + 2 H2O ----> 2 NaOH + H2
2 K + 2 H2O ----> 2 KOH + H2
 
#3 Energy Of Candy Gummi Bears Vs. M&M's Experiment
Hyperactive kids, could this be the cause? This demonstration will open your eyes to the amount of energy stored in these little candies. 1 Gummi Bear vs. 3  M&M's They react with molten Potassium Chlorate..... if you really need to know.

#2 Magnesium Oxidation in Dry Ice 

This reaction is between metallic magnesium and carbon dioxide. Magnesium reacts with oxygen in the air to form magnesium oxide, but when the only source of oxygen is from CO2 the reaction becomes much more energetic. The products are white magnesium oxide and blck carbon. 2Mg + CO2--> 2MgO + C
 
#1 Elephant Toothpaste (Old Foamy)
Elephant toothpaste is the name given to the catalyzed decomposition reaction of 30% hydrogen peroxide that uses soap to collect the oxgen gas that is produced. It is a favorite of most students at chemistry shows.
