Chemistry Videos Showing Demonstrations and Experiments

These are chemistry videos that show how to make chemicals and perform cool chemistry demonstrations and experiments.

Non-Toxic Lava Lamp Video

You can make your own lava lamp using safe household ingredients. Anne Helmenstine

The original lava lamp actually isn't something you would want to make or break open since you would have to contend with electrical wiring and toxic chemicals. Fortunately, you can make a facsimile of a lava lamp without the risk of electrocution or poisoning. See how to make a non-toxic rechargeable lava lamp. More »

Salt Crystal Garden VIdeo

This is a classic chemistry demonstration in which salt crystals are grown on a cardboard tube. See time lapse photography of the crystal growth. More »

Glowing Mentos Fountain Video

If you use diet tonic water, you can get a glowing mentos and diet soda geyser. — If you use diet tonic water instead of diet cola and shine a black light on the bottle, you can get a glowing mentos and diet soda geyser. Anne Helmenstine

If you drop Mentos candies into diet cola you get a shooting fountain of liquid. You can use another liquid to get a fountain of liquid that glows in the dark! More »

Magic Milk Color Wheel Video

Add a few drops of food coloring to a plate of milk. Wet a cotton swab in dishwashing detergent and dip it in the center of the plate. What happens?. Anne Helmenstine

Add drops of food coloring to milk. If you touch the milk, your finger gets wet but nothing really happens. If you add the secret ingredient, the milk will swirl the colors around, as if by magic. More »

Pepper and Water Science Magic Trick

All you need is water, pepper, and a drop of detergent to perform the pepper trick. Anne Helmenstine

This video shows how you can cause pepper sprinkled on ordinary water to skitter away from your finger. The project is a nice way to illustrate the concepts of emulsifiers and detergents. More »

Dry Ice Crystal Ball Video

This is a dry ice bubble. — If you coat a container of water and dry ice with bubble solution you will get a bubble that sort of resembles a crystal ball. Anne Helmenstine

This video shows how to use dry ice and bubble solution to make a stable 'crystal ball' filled with swirling fog. More »

Green Fire Jack-o-Lantern Video

Use colored fire in your Halloween pumpkin. Anne Helmenstine

Ordinary Halloween jack-o-lanterns are pretty awesome, but a jack-o-lantern filled with green fire is even better. This is a simple effect to achieve, relying on basic chemistry. More »

Alum Crystal Time Lapse Photography

Alum crystals are popular crystals to grow. — Alum crystals are popular crystals to grow because the ingredient may be purchased at the grocery store and the crystals only take a few hours to grow. Todd Helmenstine

Alum crystals are some of the easiest and quickest crystals you can grow. This is a time lapse video that shows you what to expect when growing alum crystals. More »

See Magic Rocks Grow

You can grow an underwater chemical garden while you watch. — Sodium silicate is the 'secret' ingredient in Magic Rocks that allows you to grow an underwater crystal garden while you watch. Anne Helmenstine

See Magic Rocks grow through the magic of time-lapse photography. Modern Magic Rocks grow more quickly than the old Magic Rocks, plus the colors seem more vibrant. This video compresses 12 hours of crystal growth into a minute and a half. More »

Blue Color Change Chem Demo

Many copper complexes are bright blue. — The vivid blue of this solution results from an amino-copper complex produced from mixing copper sulfate with dilute ammonia. Anne Helmenstine

See how to perform a blue color change chemistry demonstration using household chemicals. The reaction goes from pale blue to opaque sky blue to translucent royal blue. More »

Mood Ring Colors and Meanings

Most mood rings change from black to yellow, green and then blue. A black mood ring may indicate the ring is cold or that the crystals have become unresponsive. Anne Helmenstine

This video examines how mood rings work as well as what common mood ring colors are and what mood ring colors mean. More »

Green Copper Flames

These green flames are produced by the emission of excited copper ions. — These green flames are produced by the emission of excited copper ions when copper sulfate is added to burning alcohol. Anne Helmenstine

Learn how to use a common copper-based household product to produce vivid green flames. This video shows you what to do and what to expect. More »

Crystal Ice Bulb

Make a glowing ice bulb using an LED and watch battery. Anne Helmenstine

This video explains how to make a crystal ball of ice that glows lit from within by LEDs. The ice bulb can be used in drinks, fountains or anywhere you like. The ice bulb can be made in any single color or you can make a multicolored sphere. More »

Fire in a Glass Project

Pour water into a shallow dish, light a match in the center of the dish and cover it with a glass. The water will be drawn into the glass. Anne Helmenstine

This is a video of a science "trick" where you place a glass over a flame that is sitting in a dish of water. When the flame is extinguished, the level of the water in the glass rises as if by magic. More »

Burning Money Video

This $20 is on fire, but it is not being consumed by the flames. Do you know how the trick is done?. Anne Helmenstine

Light a bill on fire, yet it won't burn! Actually, it will burn unless you know how to do the trick. This video explains the science behind the burning money trick and shows you what to expect. More »

What Glows Under Black Light? - Video

This glowing jellyfish is the moon jelly. — This glowing jellyfish is the moon jelly, Aurelia aurita. Proteins in many jellyfish fluoresce or appear to glow when exposed to ultraviolet light. Hans Hillewaert

Here's a look at some of the materials that glow when exposed to a black light, including living organisms and common everyday chemicals. More »

Fire Ball Magic Trick Video

This video shows you how to make fireballs that burn with a flame cool enough that you can juggle them or use them for other types of fire displays. More »

Smoking Fingers Video

Make your fingers smoke, as if by magic. However, there's science behind this trick, not magic. Anne Helmenstine

See how to make your fingers smoke, without any fire. Also, if you perform this project in the dark, your fingers will glow an eerie faint green. This video shows you how to perform the smoking fingers trick. More »

Violet Flames Video

It's easy to make violet fire. Just ignite a mixture of salt substitute and methanol. Anne Helmenstine

You can gain information about the chemistry of a compound by the color of flame it produces. This video explains how to use common potassium compounds to produce violet flames. More »

Crystal Frost Window Project

Paint a window with a solution that turns into crystal frost right before your eyes. Anne Helmenstine
