Fluorescent Tornado

Key Takeaways Fluorescein is a dark red solid but when dropped in water, the solution takes on a bright, vibrant green color.  By using a magnetic stirrer, a strong downward force is applied to the dye. This inhibits the dye from spreading, creating a tornado-like look Equipment & Chemicals Beaker (any size) Fluorescein disodium salt… Continue reading Fluorescent Tornado

How to make Singlet Oxygen

Key Takeaways Singlet oxygen is a special excited version of normal molecular oxygen. In solution, two singlet oxygen molecules crash into each other and release a flash of light which we see as a red glow. Outside of this reaction, singlet oxygen is something that’s pretty pervasive in the natural world. Lots of compounds when… Continue reading How to make Singlet Oxygen

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
