Thanks for all the responses to the last week's riddle. You' re awesome and all of you were right.:-)
This one is hopefully a little harder (and a really tough one is coming next Saturday <evil laugh>).
Without further ado, tell me whats on the photo.
You can check out the previous challenge here.
And as usual, the answer will be posted here next weekend.
Update! Sorry for my late update, but I was totally busy in the last few days because Im moving back to Slovenia. Yes, my work in USA is done, Im finally going back home.
So, none really guessed what is on the photo, some of you were close.
It was Erlenmeyer flask in the sink full of dry ice.
