Glowing Water Video

Glowing Water
Anne Helmenstine

This glowing water video shows you two ways to make water glow. One is suitable for making glowing fountains or other decorations while the other can be used to make glow-in-the-dark drinks.

What Glows Under Black Lights? - Video

The quinine in tonic water causes it to grow bright blue under a black light.
Anne Helmenstine
Black lights are lights that emit ultraviolet radiation. Since you can't see ultraviolet light, the lights can be invisible or "black" to your eyes. Many materials that absort black light re-release less energetic light in the visible spectrum, causing them to glow. This video looks at common materials that glow in the dark under black lights.

Slime Video

You can make polymer slime using common household ingredients.
Anne Helmenstine
Slime is fun material that you can make yourself using common household ingredients. See how to make slime at home, and learn about the chemical process that occurs to form it.

Make a Smoke Bomb

This homemade smoke bomb is easy to make and only requires two ingredients.
Anne Helmenstine
Smoke bombs are the easiest and safest do-it-yourself firework project. You only need two inexpensive, non-toxic ingredients and it only takes minutes to make. Watch and learn how you can cook up a smoke bomb at home.

Make Hot Ice (Sodium Acetate)

You can supercool sodium acetate and cause it to crystallize on command.
Anne Helmenstine
All you need are two common kitchen ingredients to make hot ice - a non-toxic chemical that crystallizes when you touch it into a material that looks like ice except it gives off heat. See how to make hot ice and get ideas for fun hot ice activities.

Green Fire

Dr. Helmenstine demonstrates how easy it is to make green fire using boric acid.
Anne Helmenstine
If you've been wanting to make colored fire, but weren't sure quite what to do or what to expect, then watch my new green fire video tutorial. You can make the fire in pretty much any color you like simply by substituting one of the other colored fire chemicals for the boric acid used to make green fire.

Make Homemade Rock Candy (Grow Sugar Crystals)

Here's a stick of red rock candy.
Anne Helmenstine
You don't have to visit a candy store to get colorful rock candy. See how easy it is to grow your own sparkling (and tasty) rock candy crystals at home.

Anne Helmenstine
Here's a chemistry trick where you set your money on fire, yet you don't actually burn it. Are you wondering how it's done? See what to do!

Make a Chemical Volcano

This chemical volcano creates a dramatic eruption with colored lava.
Anne Helmenstine
The baking soda and vinegar volcano is the classic chemical volcano that you see at science fairs. Watch how easy it is to make a chemical volcano that produces a memorable eruption.

Cabbage pH Test Strips

These pH paper test strips were made using coffee filters dipped in red cabbage juice.
Anne Helmenstine
