Item matched the description. A few tiny specs will make a liter of water glow bright green. Used it for a Halloween scientific glass display; it worked awesome and got lots of interest.
Fluorescein is very handy for finding leaks, among other purposes. A small amount goes a long ways. Glad I could get the amount I need at a decent price
This is pretty cool stuff
I got this for my 10yr old. It was pretty neat to watch the Fluorescein in the water the first time I'm just not sure what else to do with this powder now though.
