Introduction: Make Flowers Glow in the Dark With Highlighter Fluid and UV Light

About: NurdRage is a dedicate group of science nerds trying to further amateur science with direct how-to instructions in video format. We saw what was already online and we thought "we could do better"... …

In this video we make white carnation flowers glow in the dark when exposed to ultraviolet light.

What we're essentially going is making them fluorescent. To do this we get a fluorescent highlighter and open it up to get the foam ink cartridge. Then squeeze a few drops of the ink into a cup of water. Place the base of a white carnation flower into the solution and cut the stem underneath. Leave the flower overnight for the solution to absorb through.

The next day, simply shine an ultraviolet light onto the flower to cause the fluorescent dye to glow.
