How do wind tunnels help sports teams?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do wind tunnels help sports teams?

The Big Idea

Air pushes against everything that moves! Wind tunnels help teams beat it. Let's see how.

A Tunnel

Step one: A Tunnel. A wind tunnel is a tunnel where fans blow air over an object. Scientists can see and measure how air moves around it.

Testing Teams

Step two: Testing Teams. Cyclists, skiers, and bobsled teams sit or stand in tunnels to test equipment, clothing, and positions. Smoke or sensors show where air swirls.

Tiny Gains

Step three: Tiny Gains. Small changes in posture or helmets can save fractions of seconds in a race. That can be the difference between first and second.

A Closer Look

Let's take a closer look! Blow air. Shows swirls. Measure drag. Test positions.

Quick Facts

Quick facts! Some wind tunnels are big enough to fit a whole car. Smoke shows swirls. Helmets get tested. Save fractions of seconds.

Think Like a Scientist

Now, think like a scientist! With a grown-up, turn on a fan. Hold a streamer in front of it. Watch how it flutters. Hold it at different spots. Where does the air swirl most?

Outro

A wind tunnel uses fans to blow air over an object so scientists can measure how air moves. Cyclists, skiers, and bobsled teams test gear and positions there, and small changes can save fractions of seconds. Science is amazing! Keep asking questions! The more you look around, the more wonders you will find, so keep your eyes open! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download!
