"Exploring Products - Nano Sand" is a hands-on activity exploring how water behaves differently when it comes in contact with nano sand and regular sand. Visitors learn about the hydrophobic properties of nano sand.
“Magic Sand” is a cart demo that demonstrates how changing nanoscale changes in a material can affect how that material behaves at the macroscale. Visitors learn that hydrophobic surfaces repel water and that “magic” sand repels water because of a nanoscale hydrophobic coating on the grains of sand. During the program, compare how magic sand and regular sand interact with water.
“Nano sand” is a product that was originally invented to help clean up oil spills in water. Since the “nano sand” is hydrophobic, it does not let water molecules pass through. It does, however, let oil molecules pass through. When oil-contaminated water is exposed to “magic sand”, the oil passes through and leaves clean water behind. And when “magic sand” is sprinkled on top of oil spills, the sand binds with the oil and creates oil- filled sand clumps that fall to the bottom of an ocean or lake.
Purpose of the lesson is to: • Explore the properties of molecular bonding • Introduce students to the engineering of hydrophobic surface. • Demonstrate the concepts of hydrophobic and hydrophilic behavior.
