A stir plate is a great investment.
Then Tubercle got his by thinking quick.
The boss got me to help him one day to clean out a storage area at work and we were throwing a bunch of stuff away. He picked up a stir plate and said "what is this"?
The Tubercle said "Not sure
, but it looks dangerous. I better take it out of here right away and dispose of it". He handed it to me and said "Yea, I guess you're right".
Straight to the parking lot.....
