Chemical demonstrations
1) Green Serpent A good demonstration for the study of catalysts.
2) Magic wine bar Commonly used in junior science for the introduction of chemical reactions or as part of a science show.
3) Rags to riches Demonstrates the making of an alloy.
4) Microwave energy This demonstration shows light energy emitted from a metal filament (light bulb) when bombarded with microwave energy. This demonstration can be used when discussing atomic energy levels.
5) Explosive bubbles Demonstrates the nature of an exothermic reaction with the production of light and heat as methane burns in oxygen.
6) Exploding can (hydrogen) Another very impressive exothermic reaction demonstrates the release of energy when hydrogen and oxygen react to form water. The demonstration is very loud and proper ear protection must be used. Read the safety instructions first.
7) Spontaneous combustion  
8) Explosive fine powders  
9) Magic blue bottle Oxidation / reduction
10) Rusting in oxygen This quick rusting reaction demonstrates the increase in the rate of reaction when surface area and the concentration of reactants is increased. Material needed are oxygen cylinder, gas jar, bunsen burner, steel wool and tongs. The gas jar, seen in the video, is filled with oxygen gas.
11) Carbon dioxide smoke This is a fun activity with dry ice. Can be used for science shows or when studying the properties of gasses.
12) Precipitate reactions(Click) Click on the blue writing. These reaction can be demonstrated in junior chemistry classes when studying chemical reactions or in senior chemistry in the study of ionic formulae, ionic equations or precipitates.
13) Slime Discussion of polymers and inter-molecular bonding.
14) Light from burning metal(magnesium) Exothermic reactions and the conversion of chemical energy into light and heat.
15) Metals that burn in water(sodium) Demonstration is appropriate to the discussion of the behaviour of reactive metals.
16) Another spontaneous ignition (KMnO4)  
17) A salt lava lamp. This activity can be conducted when studying solubility. The demonstration works because of the difference in solubility of oil and salt.
18) Never ending rope (nylon) This demonstration can be used when studying polymers and polymerisation. It involves the synthesis of nylon and when you view the video it is obvious why this demonstration is named the never ending rope.
19) Coal from sugar Demonstrates the dehydrating action of sulfuric acid for organic compounds.
20) Flammable smoke from candle or from wood fire This demonstration can be used to demonstrate cracking when studying hydrocarbons and the petrochemical industry.
21) Boiling point of water The relationship between air pressure and boiling point of water is clearly shown in this demonstration.
22) Sugar as a fuel

Demonstrates the rapid oxidation of sugar in the presence of an oxidant. This demonstration is useful for the study of rate of reaction. Increased surface area and increased concentration of reactant, such as oxygen, will accelerate the rate of reaction.

Great reaction to also demonstrate the energy in common food and to demonstrate how a compound, sugar, can prodduce and element, carbon.

23) Genie in a bottle. This reaction is similar to the Serpent. It shows the rapid rate of a catalysed reaction. Hydrogen peroxide decomposes to form water vapour, oxygen and a great deal of heat. The rapid expansion of the water vapour produces a white smoke that rapidly escapes from the flask, similar to genie in a bottle.
24) Magnesium burning in carbon dioxide gas. An excellent demonstration to show that not all fires in the laboratory can be extinguished by carbon dioxide gas. An opportunity to show this reaction exists when studying safety in lab.
Also useful to demonstrate oxidation reduction reactions.
25) Start a fire with a drop of water A useful demonstration for senior chemistry when studying redox reactions. It can also be used as a demonstration in the introduction to safety in the lab. This demonstration is useful in emphasizing the fact that students should never mix chemicals with out permission.
26) Guncotton. A great demonstration to show the change in properties of a common substance when it is slightly altered chemically.
27) Chemical serpents. A fun demonstration to show how sugar, a common compound, can form an element, carbon.
28) Thermite reaction A dynamic demonstration revealing the energy release when iron oxide is reduced by aluminium to iron. Demonstration can be used in senior chemistry for redox reaction or for a great exothermic reaction in junior classes,
29) Chemical snakes An interesting reaction along the same theme as slime. Great for the study of plastics, polymers and polymerisation.
30) Drought in a cup A magic trick to demostrate the nature of hydrogels. Sodium polyacrylate is used to absorb water and demostrates one of the uses of plastics as used in nappies.
31) Sticky water An interesting way to convey the strength of water's surface tension.
32) Fireworks in milk An exciting and simple demonstration of the action of surfactants. Keep in mind that this is a simple experiment whose explanation can be very complex.
33) Fireworks in a test tube A spectacular demonstration of oxidation of an alcohol. Can be used when covering redox reactions, oxidation numbers and oxidants..
34) Blue water with a battery A demonstration involving redox reactions, electrolysis and acid-base indicators.
35) Ammonia fountain Solubility of ammonia in water and its reaction as a weak base.
36) Glycerol and permenganate Useful as a demonstration of the relationship of surface area and rate of reaction.
