1) And now the tasting test ... 2) And now shake it a bit ... 3) In which glass was my mineral water? 4) Why does that stuff burn with a green flame?!? 5) And now the detonating gas problem. 6) This is a completely safe experimental setup. 7) Now you can take the protection window away ... 8) Where do all those holes in my kettle come from? 9) And now a cigarette ...
A physicist, biologist and a chemist were going to the ocean for the first time.
The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves and walked into the ocean. Obviously he was drowned and never returned.
The biologist said he wanted to do research on the flora and fauna inside the ocean and walked inside the ocean. He too, never returned.
The chemist waited for a long time and afterwards, wrote the observation, "The physicist and the biologist are soluble in ocean water".
Don't LOOK at anything in a physics lab. Don't TASTE anything in a chemistry lab. Don't SMELL anything in a biology lab. Don't TOUCH anything in a medical lab.
and, most importantly:
Don't LISTEN to anything in a philosophy department.
Chemist's last words
