https://www.thesun.co.uk/fabulous/3460992/how-to-make-slime-safely-recipe-borax-boron-unsafe-toys/

Slime is super fun to play with – and it is not even hard to make. Here’s how: Key Takeaways Most types of slime are also examples of polymers. Polymers are molecules made by linking together chains of subunits. The slime formation is a reaction between PVA (polyvinyl alcohol) and boric acid Equipment & Chemicals White… Continue reading How to Make Slime with Borax and Glue

Dyeing wool with Indigo

Indigo dyeing is challenging because the dye is not soluble in water.  Key Takeaways As the dye is not water-soluble in water, it first has to be reduced to a water-soluble form The reduced form is also called “white indigo” or “leuco-indigo” After removing the dyed cloth from the dyeing solution, it quickly turns blue… Continue reading Dyeing wool with Indigo

Fluorescent Slime

Fluorescent Slime glowing under UV light

Slime is super fun to play with, but with just one key ingredient you can make it glow like crazy! Here is what you need:  Key Takeaways Most types of slime are also examples of polymers. Polymers are molecules made by linking together chains of subunits. Slime becomes fluorescent, when a fluorescent dye, like rhodamine or… Continue reading Fluorescent Slime

Potassium permanganate and Glycerin reaction

Smoke is generated in a lot of chemical reactions, but have you ever created purple smoke? Here is how! Key Takeaways Potassium Permanganate (KMnO4) is a dark purple solid that is used as a very powerful oxidizing agent KMnO4 oxidizes Glycerin (high concentration of C-H bonds, acts as a fuel)  The energy released is enough… Continue reading Chemical Fire Starter

Iodine Clock Experiment

The classic iodine clock reaction demonstrates the properties of chemical kinetics through its mesmerizing change in color, and it is sure to fascinate you and perhaps your audience. Key Takeaways The blue-black color observed in Parts I and II occurs as a result of two separate reactions In the presence of starch, iodine forms the… Continue reading Iodine Clock Experiment

Ammonium Dichromate Volcano

With just one chemical you can create a realistic-looking chemistry volcano. The chemical is called Ammonium Dichromate and here is how to do the experiment: Key Takeaways The volcano is made up by a pile of ammonium dichromate While the ammonium dichromate decomposes, it gives off orange sparks and throws the green chromium(III) oxide crystals… Continue reading Ammonium Dichromate Volcano

How to make Red Fire

Lithium ions coloring a flame red

We are all used to flame being yellowy-orange. But can we turn a flame red? Yes, here’s how! Key Takeaways Many metals and non-metals turn flame different colors Alkali and earth alkali metals have low ionization energies  Lithium salts give a purplish-red, and strontium ones a red flame Equipment & Chemicals The preparation is quite… Continue reading How to make Red Fire

Fluorescence Experiment

Fluorescein dropped in water under UV light

An easy way to make scary-looking green water. You will also learn how the chemical effect “fluorescence” works. Key Takeaways Fluorescein is a dark red solid but when dropped in water, the solution takes on a bright, vibrant green colour.  This effect only works under UV-light. Sunlight will also work, since it is partly UV-light… Continue reading Fluorescence Experiment

Luminol Reaction

Make your own glowing light with a little chemistry trick and the power of luminol! Key Takeaways The glow is produced from a chemiluminescent reaction Luminol is the key ingredient in this reaction. It is oxidised by hydrogen peroxide Light is released, because electrons fall from an excited state back to the ground state Equipment… Continue reading Luminol Reaction

How to Make Flaming Gel

By using a little chemistry you can turn household ingredients in a flaming jelly. This is an easy fire chemistry project that you can do at home. Key Takeaways Camping fuel and fire gels are used to generate a steady, long-lived flame Ethanol is a very simple molecule and commonly found in liqueur and cleaning… Continue reading How to Make Flaming Gel
