And of course instructors must always remind the students not to eat any of the chemicals. Of course, as silly and idiotic as it sounds, there is
actually reason why they say not to eat the stuff…because people do, I witnessed it with my own eyes….we were doing a lab in class using a
fine CuSO4 * 5H2O powder and a girl said, “it sure does look like pixie [stick] dust, I bet it is”, and then proceeded to lick her finger
and taste it! She quickly learned it was not candy and had to go get a drink very immediately. |
