Just remember that acetone is nasty stuff in terms of health hazard, including
effects from inhaling, getting into eyes, or onto skin. Also, it's highly
flamable (including the vapors). Open containers of acetone should be under a
hood or area of high ventilation (which of course causes it to evaporate even
more quickly). If you're unaware or unsure of the hazards, take a look at an
MSDS (Materials Safety Data Sheet), such as the one at
<http://www.jtbaker.com/msds/englishhtml/a0446.htm>.
Cheers,
