While making dinner tonight I got a small amount of turmeric on my hands. The stuff stains like crazy and I started getting yellow all over the place, so I wiped my hands on a damp paper towel. Since then, I've washed my hands two or three times. Any visible trace of the turmeric is long gone.
I was screwing around with a UV flashlight when I noticed my hands were glowing. I retrieved the paper towel from the trash, shined the flashlight on it and it lit up like a Christmas tree.
I didn't know that turmeric had fluorescent properties.
