Acetone Problems

Hey guys!   So last week, I accidentally dropped my cleanup brush (an eyeliner brush) in my bottle of acetone.  D'oh!  Since I just finished doing my nails, I didn't want to fish it out right away, so I told myself that I'd get it out later.  Me, being my typical forgetful self, forgot that the brush was in there and didn't remember until 3 days later.  I looked at the acetone bottle and saw this:

Look at that, pure black!  I shook the bottle, and I didn't hear anything solid inside.  This is what was supposed to be inside (I bought the same exact brush again, because I really like the control this one gives me over my clean-up):

(ew...pchem hw)

The acetone melted my brush!  Completely gone....  Ladies and gentlemen: presenting to you the destructive potency of acetone.  Yay chemicals!
