How does a pitcher plant inspire slippery surfaces?

Video · 1:49 · Crafty Clover explains, from A Million Whys Book 26

A pitcher plant has a slippery rim, and insects that land on it slide into the plant’s watery pool. Scientists at Harvard studied it around 2011 and made a surface soaked with a thin layer of liquid that stays locked in place. Honey, ketchup, and even oil slide right off. Companies now explore this idea for bottle linings, pipes, and coatings so things do not stick.

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a pitcher plant inspire slippery surfaces?

The Big Idea

A pitcher plant has a slippery trap! Insects slide right in. Scientists copied it to make super-slippery surfaces.

Slippery Rim

Step one: Slippery Rim. A pitcher plant has a slippery rim. Insects that land on it slide into the plant's watery pool.

Liquid Layer

Step two: Liquid Layer. Scientists at Harvard studied it around 2011. They made a surface soaked with a thin layer of liquid that stays locked in place.

Nothing Sticks

Step three: Nothing Sticks. Honey, ketchup, and even oil slide right off. Companies now explore this idea for bottle linings, pipes, and coatings.

A Closer Look

Let's take a closer look! The rim is slick. A film coats it. Honey slides off. Bottles empty fully.

Quick Facts

Quick facts! Some pitcher plants are slippery enough that ants cannot climb out. No more stuck ketchup. Harvard studied it. Pipes stay clear.

Think Like a Scientist

Now, think like a scientist! Put a drop of honey on a plain plate. Put another on a plate with a thin film of cooking oil. Tilt both plates the same amount. Which drop slides first? Wash the plates well afterward.

Outro

A pitcher plant inspires slippery surfaces because its slick rim makes insects slide in. Scientists made liquid-locked surfaces that honey, ketchup, and oil slide right off. Science is amazing!
