Yesterday, I had some pre-measured watercolor inks mixed with liquid soap sitting on a counter-top. They were to be used by another class later in the day. One of my high-school students accidentally knocked a few over (he was soo upset!). And, he helped me to clean it up. At one point, he was so taken with how "cool" the spill looked he asked to take a picture.
Nothing like a girl in heels with a mop.
