Chemical Fun and Magic Show - Part II
- The matchless explosion
Red phosphorus and potassium chlorate is detonated with ahammer and energy forms in reactions are discussed.
- The "hot" diaper trick
Alcohol is used to produce a cool flame which doesn't burn up a diaper.
- The ammonia fountain
The physical change of dissolving ammonia gas in water is illustrated.
- Hot and cold/liquid to solid/solid to liquid
Sterno is produced from two liquids and a cold liquid is produced from two solids.
- The electrolysis of water
Water is broken down into hydrogen and oxygen gas which are then tested. The gases are combined explosively in pop bottles and a trick condensation of water is done.
- Balloon explosions
The effect of the size of balloons on explosions is discussed and hydrogen, hydrogen/oxygen, and methane filled balloons are contrasted.
- A chemical volcano
Oxidation is discussed as magnesium is burned and ammonium dichromate is converted into chromium iii oxide, water, and nitrogen gas.
- Burning magnesium in dry ice
The fact that burning magnesium is not extinguished by CO2 is illustrated and then the oxidation of magnesium using dry ice to produce carbon and magnesium oxide is dramatically shown.
- Sugar, carbon and the oxygen cycle
The action of concentrated sulfuric acid on sugar illustrates the carbon content of sugar and the heat produced leads to a discussion of photosynthesis, respiration, the energy content of food, and the oxygen cycle.
- Potassium permanganate and glycerine
The thermite reaction making molten iron.
