How do you make bouncy balls without borax?

To make a bouncy ball without using Borax, you can use baking soda, glue, water, and food coloring or cornstarch, water, and food coloring. Simply combine your ingredients to make a bouncy toy that you can play with at home.

What is the science behind making bouncy balls?

The Science of Bouncy Balls Making a bouncy ball is an example of a chemical reaction. This reaction happens between the Borax and glue. The Borax is the cross-linker for the glue’s polymer molecules. This creates chains of molecules that stay together when your child plays with the ball.

What is the science behind bouncy balls?

What makes a homemade bouncy ball bounce?

When the glue mixture was added to the borax, the borax acted as a cross-linker, hooking the glue’s molecules together to form the rubbery bouncy ball. The cornstarch was added to help bind the molecules together so the ball would hold its shape. The ball can bounce because of the cross-linked polymers.

What is inside a bouncy ball?

Store-bought bouncy balls are made of rubber, another material that is made up of polymers. When the bouncy ball is stretched, these polymer chains uncoil and straighten. When released, the chains coil back up again. This makes the material stretchy and bouncy.

What kind of rubber is used to make bouncy balls?

A superball or power ball is a bouncy ball composed of a type of synthetic rubber (originally a hard elastomer Polybutadiene alloy named Zectron) invented in 1964, which has a higher coefficient of restitution (0.92) than older balls such as the Spaldeen so that when dropped from a moderate height onto a level hard surface, it will bounce nearly all the way back up.

What materials are used in bouncy balls?

Before you make bouncing polymer balls, you will need to gather a few materials: Borax (found in the laundry section of the store) Cornstarch (found in the baking section of the store) White glue (e.g., Elmer’s glue, which makes an opaque ball) or blue or clear school glue (which makes a translucent ball) Warm water Food coloring (optional) Measuring spoons Spoon or craft stick (to stir the mixture)

What is the thing that makes a rubber ball bounce?

The force of the ball hitting the hard ground puts an equal force back on the ball, causing it to bounce up. This happens because balls are made out of an elastic material like rubber, which means they can be dented or stretched and then return to their normal shape.

What makes a rubber ball bounce?

Balls made of elastic materials such as rubber bounce because the material stretches and deforms when they hit a surface and then reform back into their original shapes, which releases energy into a kinetic form, causing the rubber ball to bounce.
