Replying to IPod help

so mum decided to put my ipod through the wash. luckily it was my old one, but still, i liked having two...
im trying to work out how the hell i can open the actual ipod. i remember ages ago i dropped it and it split open then i put it back together. but ive tried that and it doesnt work. ive been told that if i heat it up with a hair dryer the glue should melt and itll open up. has anyone tried that? im curious. if no one can give me a reason not to do it, well im gonna give it a shot. but yeah let me know if i could do some permanent damage
