Why did early parachutes swing wildly, and how did a vent hole help?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why did early parachutes swing wildly, and how did a vent hole help?

The Big Idea

Early parachutes swung back and forth like crazy! One jumper even felt sick. A simple hole fixed it.

First Jump

Step one: First Jump. The first parachutes were big, closed umbrellas of cloth. When Andre-Jacques Garnerin jumped from a balloon over Paris in 1797, his parachute swung so hard that he felt sick.

Spilling Air

Step two: Spilling Air. Air kept spilling out from the edges, first on one side and then the other. That made the parachute rock back and forth.

The Vent

Step three: The Vent. A French astronomer, Joseph Lalande, suggested a hole at the top. Air escapes smoothly through it, so the parachute steadies.

A Closer Look

Let's take a closer look! The canopy catches air. The vent lets air out. Lines connect. The jumper hangs below.

Quick Facts

Quick facts! Many round parachutes today still have a small opening at the top, or vents, so they fall steadily. An astronomer helped. Jumped from a balloon. Air spilled unevenly.

Think Like a Scientist

Now, think like a scientist! Make two parachutes from coffee filters, string, and a small washer. With a grown-up, cut a small hole in the top of one. Drop both from a low, safe spot, like a sturdy step. Watch them fall. Which one falls straighter?

Outro

Early parachutes swung wildly because air spilled out from one edge, then the other. A vent hole at the top, suggested by Joseph Lalande, lets air escape smoothly so parachutes steady.
