A t3i has a powerful flash capacitor inside. If you take of the front cover, it could very well knock you out if you hit it, possibly kill you. It has an added bonus of using really long leads that stick out near the bottom of the camera. If the camera got wet, it’s most likely toast. The power board (home to the capacitor) and the mainboard will corrode at any point that carries voltage within minutes. Sell it on ebay for 50 bucks and move on.
