You should have clearly seen that the tonic water glowed a brilliant, bright blue color when you put it under the ultraviolet black light (before adding bleach).
When you added a few drops of bleach to the tonic water, did it stop fluorescing under the ultraviolet black light? Does the JELL-O made with tonic water glow under an ultraviolet black light? (Tip: Try preparing the JELL-O with water that is hot but not quite boiling.) Extra: You could try preparing JELL-O with tonic water instead of regular water.When other oxidizing agents are added to tonic water, do they have the same effect on its glow under an ultraviolet black light that bleach does?
Some other common household oxidizing agents include hydrogen peroxide and OxiClean (which contains sodium percarbonate).
Pour about one cup of tonic water into a clear plastic, disposable cup.
#DRY ICE IN TONIC WATER BLACK LIGHT SKIN#
Avoid looking directly at the ultraviolet "black light" and shining it on your skin because the light can damage your eyes and skin.Do not drink the bleach or the tonic water mixed with the bleach, and be careful to not get it on your skin. Adult assistance is required when handling bleach. When handling the bleach, be sure to read and follow all safety precautions listed on the container.Ultraviolet "black light" bulb (This can be purchased at a party supply store or some hardware stores.).Part of why we find things that glow under ultraviolet lights-such as some minerals, fish and tonic water-to be fascinating is because we cannot see the (ultraviolet) light they absorb but can see the visible light they emit (which is blue in the case of quinine). In general, something fluoresces because it has absorbed light energy, which makes it excited, and then it releases (or emits) light as it returns to its normal, unexcited state. Under an ultraviolet "black light," the quinine in tonic water makes the water fluoresce a brilliant, bright blue (even though only a relatively small amount of quinine is dissolved in the water). Quinine not only gives tonic water a characteristic bitter taste (which is offset today by the addition of sweeteners to bottled tonic water) but this chemical can also be very fluorescent under the right conditions. Quinine is made from the bark of a tree and has been used for centuries as a treatment for malaria.
Tonic water is a carbonated beverage that has a chemical called quinine dissolved in it. How will adding bleach affect the tonic water’s glow? Try this activity to find out!
