Sooo.
I was at a friend's lake, and we sitting on her dock. My camera was resting on the armrest of the chair, and I had the strap around my wrist, as always. Buuuuut, I got up for a second to grab my drink, and my camera fell off the chair, landed on the dock, right on the battery chamber thing, which is attatched to a spring. The chamber opened, catapulting my camera and it's battery into the lake.
I screamed bloody murder and dove in after it. Spent about twenty minutes tearfully diving to the bottom trying to retrive it. FINALLY found it, and the battery, both which had been buried in the sand and muck for a good twenty five minutes.
