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.
