How Does NASA | Afterschool Universe: Stellar Fusion Demonstration Work?

NASA’s Stellar Fusion Demonstration is like watching how the Sun makes its energy, but on a smaller, cooler scale that you can touch and see.

Imagine you have two balloons filled with special gases. When you pop them together, they start to glow and get hot, just like what happens in the middle of the Sun. This glowing and heating is called fusion, where tiny particles join together and release energy, just like when your favorite snack gets warm in the microwave.

In this demonstration, scientists use special gases that act like the inside of a star. When they're brought together under the right conditions, the gas particles begin to merge, creating light and heat, just like how the Sun gives us warmth and light.

It’s like mixing two kinds of invisible building blocks in a special container. When you push them together, they start to react, making new things and giving off energy. This is stellar fusion, the same process that powers stars and makes our Sun shine!

You can feel the heat and see the glow, just like if you were inside a giant, glowing toy ball!
