Understanding Superhydrophobicity in Nature

What is the primary function of superhydrophobicity in insects and plants?

• To attract more water

• To make them more colorful

• To repel water and prevent it from sticking

• To help them fly faster

How does the impact of a raindrop on a mosquito compare to a human experience?

• Like being hit by a small rock

• Like being hit by a tennis ball

• Like being hit by a Volkswagen Beetle

• Like being hit by a feather

Why do mosquitoes survive raindrop impacts?

• They have strong wings

• They are immune to water

• They are very heavy

• They go along with the raindrop's motion

What happens when water is dripped onto a butterfly wing?

• It gets absorbed

• It forms a puddle

• It bounces off like a rubber ball

• It spreads evenly

What is the role of nanoscale structures on insect wings?

• To store food

• To attract other insects

• To repel water by creating empty spaces

• To absorb sunlight

What is the term for water molecules sticking to each other?

• Adhesion

• Cohesion

• Diffusion

• Osmosis

What determines if a surface is hydrophobic?

• The color of the surface

• The angle between the surface and the water droplet

• The temperature of the surface

• The size of the water droplet

How do water striders manage to walk on water?

• They have large feet

• They are very light

• They have numerous tiny hairs that repel water

• They use their wings to balance

What is one technological application of superhydrophobic surfaces?

• To enhance color brightness

• To increase friction

• To absorb more water

• To create self-cleaning surfaces

Why are scientists interested in superhydrophobic structures?

• To increase water absorption

• To create heavier materials

• To develop surfaces that repel water and dirt

• To make surfaces more colorful
