Demonstration Description
Chemical Sunset Creates the Tyndall Effect in a beaker.
Chemilumiescence Create a luminescent effect akin to a commercially available glow stick.
CO2 Fountain Generate carbon dioxide and demonstrate that it has properties very different from that of air.
CO2 States Use dry ice to demonstrate the three phases of matter in a single demonstration.
Crushed Can Demonstrate gas laws and the action of atmospheric pressure by crushing a soft drink can.
Egg in a Flask Watch as atmospheric pressure forces a boiled egg through an impossible opening.
Elephant Toothpaste Catalytic decomposition of hydrogen peroxide rapidly releases oxygen gas, producing large quantity of foam.
Endothermic Glue Witness the obvious effects of an endotheric chemical reaction.
Erlenmeyer's Balloon Use gas laws and atmospheric pressure to line the interior of an Erlenmeyer flask with a balloon.
Filling Flask Demonstrate the action of atmospheric pressure to spontaneously fill a flask with water.
Genie in a Bottle Hydrogen Peroxide decomposes to form oxygen and hydrogen gas. Catalysis is demonstrated to speed up the reaction. An exothermic reaction is produced, providing a Genie-like effect
Gold and Silver Pennies Demonstrate the techniquie of galvanization.
Hollow Pennies Evidence of the activity series of metals and the multiple-layer nature of United States pennies.
Lycopodium Dust Explosion A demonstration of the effect of surface area on combustion using a controlled, miniature dust explosion.
Mentos Eruption A sudden reduction in gas solubility results in the rapid release of the gas from a soft drink bottle.
Natural Gas Bubble Bath An investigation of surface tension, surfactants, the Marangoni effect, and combustion reactions.
Pyrotechnic Gummy Bear A decomposition reaction of attention-grabbing quality.
Salt Water Hazard Demonstrate how the density of liquids and buoyancy are related.
Solid Water A demonstration of the phenomenom of super-saturation.
Whoosh Bottle An attention-grabbing combustion reaction.
