Does anyone keep the shells of their dead snails?

I kept the shell of my 1st snail that died. It was a yellow mystery snail. For some reason the snail never grew when I brought it home. It lived for about a month or two, then died. I kept it shell.

I now have a blue mystery snail. This snail grew like crazy and is now the size of a golf ball.
 
I took the dead snail out of the tank and put it in a seperate cup of water. I changed the water daily - otherwise it stunk to bad. Eventually the snail fell out of the shell.
 
I pull the body off with a tweezer.

I believe boiling them also works.
 
lol..sounds gross, eh? i keep mine in the tank and they fall apart after a while. when they die i just take them out of the tank and rip their body out for my other guys to eat and then throw the shell back in. it's not really that gross....i've done much yuckier things.
