"Exploring Size - Measure Yourself" is a hands-on activity in which visitors mark their height on a height chart and discover how tall they are in nanometers. They learn that although being a billion nanometers tall sounds impressive, it doesn't mean they're super tall: it means a nanometer is super small. Visitors can also measure their hands in nanometers.
"Exploring Size - Scented Solutions" is a hands on activity illustrating how small nano is. By sniffing a series of diluted scent solutions, visitors discover that nano-sized particles may be too small to see, but they're not too small to smell!
