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

Silver Tree Chemistry Experiment

This beautiful experiment shows you how to grow your own tree which magically turns copper wire to silver crystals. Key Takeaways Silver is a less reactive metal than copper, which means copper metal can force silver out of solutions of silver salts A single-displacement reaction occurs Cu + 2AgNO3 -> 2Ag + Cu(NO3)2 What you… Continue reading Silver Tree Chemistry Experiment

The best Way to make Green Fire

Trimethyl Borate ester burning with a green flame

Green is probably the coolest color to turn flames. But there is only one chemical, that will give you real, vibrant green. Here is which one: Key Takeaways This experiment uses dangerous chemicals. Please review the safety The green color is generated from a chemical called trimethyl borate Methanol is used because, on its own,… Continue reading The best Way to make Green Fire

How to make Purple Smoke

Smoke is generated in a lot of chemical reactions, but have you ever created purple smoke? Here is how! Key Takeaways This experiment deals with toxic chemicals, use proper Protection The purple “smoke” is actually no smoke, but iodine vapor During the reaction, a lot of heat is produced and occasionally sparks can be seen… Continue reading How to make Purple Smoke
