 How much acetone was that? I used about a drop's worth. I am hoping that if that blew, the resulting explosion would be much smaller than the one that you mention :-). Salvador.

 Be super careful with acetone.  I know a family whose home was heavily

Blew the exterior doors off and the workers were very badly burned.
Investigators never did figure out what ignited it.
