In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

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.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

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.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

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.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this activity, learners examine their tongue and taste buds.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
