If you flip a scale upside down and hook it to the ceiling, then release a helium balloon under it, such that the balloon pushes up into the scale...
A. What will the scale reading indicate? Will it really reflect the (negative?) weight of the balloon?
B. Will the mechanics of how a scale operates prevent it from working in an upside down position? What if you "zero it" first?
