After the results of my "Glow-Stick-Excursions" came out so well (Check out the photos here and here.), I decided today to go for another tour of the basements and conduct some more experiments with various light sources.
I used - of course - glow sticks again, a normal flashlight and a LED headlight.
I'm thinking of bringing along some candles next time around...
I also took some photos of myself with my new fashion accessory ;)
