I've been playing around in my toilet tank (not the bowl; the tank is where the fresh water is) a lot lately, and I've learned that it's really not all that bad.  Toilets in general induce a negative reaction.  Bad stuff goes in there.  But the tank is generally harmless.  It just holds water that pours into the toilet bowl when it's flushed.  The water in the tank is as clean as the water coming out of the tap, so there's really no reason to fear it. #entertainment
