Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

Invisible Ink Demonstration
Source Institutions
In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
The Jelly Bean Challenge
Source Institutions
In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Monster Mallows
Source Institutions
In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

Atmospheric Collisions
Source Institutions
In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
