LOL..

I buy packages of Kool Aid (it's an unsweetened powder drink mix in small square envelopes)...I'd keep them in a cup on the table........they would regularly get dumped all over the floor and table....

For some reason moisture was getting into the packets and making the powder turn hard....

It wasn't until I figured out that the teeth marks in the envelope were the reason.....

Stimulated? YES......

behaving? NO!!!!!
