A beaker, cylinder and test tube.

Another day in the Science Lab.
Another story to tell.
Probably one of the most interesting Lab stories that I have ever encountered so far.
____________________________
We were boiling some solution.
It was purple.
And it stains.
REALLY STAINS.
Anyway, my friends and I were boiling the solution on the bunsen burner in a test tube with a glass rod in it.
Right after the experiment, we immediately took the test tube and glass rod out to clean it.
We brought it to the nearest sink.
Unfortunately, the purple liquid was stuck in the glass rod.
We couldn't figure out a way to get it out of the glass rod.
1,2,3 SQUIRT.
HA?
What was that!
The Solution squirted out of the glass rod and stained the white wall PURPLE!
What to do what to do?????
We did the usual.
Panicked.
It wasn't our fault was it????
Teacher was coming.
Panic level had increased by a percentage which doesn't even exist.
Someone took a tissue in a split second, wiped that thing off, and returned to base just on time.
Teacher came, she did not realize anything.
PHEW.
Thank goodness!
Sad to say, the stain still lies on the wall.
I wonder when someone is ever going to realize it.
