soap greater

tired of using expensive harmful (?) liquid soap, and dissatisfied with using a solid soap because it gets dirty fast, i am going to try another method: a solid soap greater. flakes dissolve quickly and you are not touching the solid soap so it doesn't get dirty.
any way its my first shot and already working well. I think I'm going to have to add a weight to push the soap down but we shall see.
the spring is just something i had lying around. 10mm outside 8 mm
inside and i had to cut it
