How much would you need to do to change the atmosphere around the box to
make it more buoyant? Maybe you could have a heater in the bottom of
the box that heated the air just under the box and a refrigerated
surface on top? Or you could have some completely unrelated device in
the room... pass an air current over the surface of the box to reduce
downward pressure? Or change the air temperature?

I can't be bothered working out how great these effects might be, but
yeah, just guessing :)
