Hmmm, i have gallon water jugs down here and use one as a door stop to the folding door to my sewing room. i have three cats i must keep out! i move the jug a lot and push back in place. one day i found it had leaked and i had an empty box sitting underneath my room heater. yikes. since then I've moved the other jugs into the room with the water heater and am very careful when moving the door stop one!
