It’s a simple, scientific way to add some variety to your UV party!
Warning! Only under adult supervision.
- mortar and pestle;
- cotton wool;
- UV light.
Shred some spinach leaves and grind them with isopropyl alcohol in a mortar. Set a funnel in a glass, insert a piece of cotton wool into the funnel, and pour the spinach brew through the funnel. Add some more alcohol and wait for it to drain through the funnel. Remove the funnel, turn off the lights, and turn on a UV light over the resulting liquid – it glows scarlet.
The cells of spinach leaves contain chlorophyll, which is released when the cells are destroyed as the leaves are ground in the mortar. Chlorophyll dissolves well in alcohol, creating a green solution. When exposed to UV light, the chlorophyll partly absorbs it and partly exudes it as a scarlet glow, lending the solution an eerie resemblance to blood.
