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 These crystals were grown from a mixture of equal parts Mrs. Stewart's Laundry Bluing (which is Prussian blue or iron(III) ferrocyanide), ammonia and salt. Anne Helmenstine 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 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 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 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 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 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 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, 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 Fireball. Anne Helmenstine 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 This video shows how to make an easy window paint that will coat the glass with crystals that resemble frost. Footage includes time-lapse photography of crystal frost growing on a window. More » How to Grow Alum Crystals - Video Alum crystals grow within a few hours. Anne Helmenstine This video tutorial demonstrates how to grow your own alum crystals, plus time lapse photography shows you what to expect from the first few hours of crystal growth.
