Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does magnetic putty swallow a magnet?

The Big Idea

Magnetic putty seems to gobble up a magnet, like a very slow monster. It is a stretchy putty that is mixed with fine iron powder. Let's find out how it swallows!

Putty With Iron

Step one: putty with iron. Magnetic putty is a stretchy, silicone-like putty that has been mixed with fine iron powder. Because of the powder, the whole blob can feel a magnet's pull.

A Slow Flow

Step two: a slow flow. When you set a magnet on the putty, the iron powder is attracted to it. The soft putty flows slowly around the magnet, and after a while it has wrapped itself all the way around.

Stronger or Weaker

Step three: stronger or weaker. If you pinch the putty, it can get stronger or weaker depending on how the powder is lined up. The putty flows like a very thick liquid but also bounces like rubber.

A Closer Look

Let's take a closer look! The putty is soft and stretchy. It is full of iron powder. The magnet pulls on the powder. So the putty creeps around the magnet.

Quick Facts

Quick facts! Magnetic putty flows like a very thick liquid. It also bounces like rubber. Iron powder lets it feel a magnet's pull. And it swallows a magnet very slowly.

Think Like a Scientist

Now, think like a scientist! If you have magnetic putty, place a toy magnet beside it. Watch it creep. Draw the putty every five minutes. Keep small magnets away from little brothers and sisters. Tell a grown-up what you discover!

Outro

Magnetic putty swallows a magnet because its iron powder is pulled toward it. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
