of course you can! but you shouldnt because itis too risky and dangerious.so dont drive a car with no fluid in its radiator.

It is because it is very cosy and warm.the material used for the making are equally costly as well.

It might be because there is a leak in your house and some water is trapped betwen the walls.

Maybe the grease might have not entered properly inbetwen the door hinges.

Of cause it is working only that it is faulty and needs repair and/or maintainance.
