Up in a puff of smoke

Tonight I was cleaning. Ok, get up off the floor now, I didn't mean to surprise you. ;) For some reason Kaelyn's school lunch bag was on the table. I picked it up and it was heavy. I know I told her a LONG time ago to empty it. You know where this is going, don't you?

I took out the ice things and took out the Tupperware sandwich box, opened it up and POOF in my face was a cloud of green smoke. BLECH! There was a full sandwich in there.

Stephanie later asked if Kaelyn put something hot in there because of the "steam" that came out. LOL You'll all be happy to know that the sandwich, Tupperware and all, is in the outside garbage can.
