text: can i ask who thinks aetone is really bad health wise? do you think acetone can harm ? acetone can permeate the fortress known as human skin, it is harmful when inhaled, may be irritating to the eyes, and skin and should never ever be ingested - not even on a double dog dare.  acetone's vapors are incredibly incindiary, so be careful not to smoke or make sparks anywhere near an open decanter of acetone or its vapors.  have fun and bee safe.
