"Exploring Properties - Surface Area" is a hands-on activity demonstrating how a material can act differently when it's nanometer-sized. Visitors compare the reaction rate of an effervescent antacid tablet that is broken in half with one that is broken into many pieces.
- Things on the nanoscale have a lot of surface area, so they react much more easily and quickly than they would if they were larger.
- Nanometer-sized things are very small, and often behave differently than larger things do.
