Science Storms: Atoms

It's all elemental

Atoms are the basic building blocks of matter, and determine the properties and behaviors of all materials. Experiment with amazing substances like shape memory alloy and ferrofluid to discover why their atomic arrangements make them behave the way they do. Take a virtual journey into the history of atomic theory. Get your hands on a virtual chemistry set: choose elements from a digitally projected periodic table, and then drag them across the tabletop to combine them and see what compounds can be made.

Create a chemical reaction

Throwing together atoms of various elements can create incredible materials. At the create a chemical reaction table, you can take a drag-and-drop approach to the elements, mixing and matching them in a virtual chemical lab. Use pucks to choose elements from a projected periodic table, and pull them into a reaction lab to see what happens. You can bring in more atoms of the same element, throw new ones into the mix or just start over. The table can also suggest combinations you might want to try. It's a fun way to learn how a single atom or molecule can be the difference between fire and fizzle.

Everything is made of atoms

The atomic structure and composition of a material can give it some unique (and useful) properties. Try out such unusual substances as shape metal alloy: after no matter how it is being bent and or crushed, it always returns to its original shape when heated. From cutting-edge foams to self-healing polymers, watch these atoms in action.

Ferrofluid

Ferrofluid is an oily liquid full of tiny magnetic particles suspended in it. The particles interact with nearby magnetic fields to create beautiful patterns rising from the liquid. Ferrofluids can repel debris, refract light and reduce friction. They can be used in applications ranging from military and space to medicine and loudspeakers. In the exhibit, you can shape a ferrofluid to your will by adjusting electromagnets above and below the tank.
