Chrissy's photos with the keyword: toxic

This photo was taken in one of my last lab courses in university. The aim was to identify unknown white powder. This was of course the most part harmless substances such as sugar, soda or similar. Since these substances, however, were unknown, they had to get all hazardous material stickers. They were then lined up in front of us students for to go to work. I have selected the image for T because I had a lot of fun in my studies and because it fits to the topic of the group "theme of the week": "Alignment". With Picasa I have reversed the tones, because in my opinion the jars so look even more toxic.
