Or whether graphene or diamond would be better for this application, given the need for rigidity. Any takers? --Jim It is conceivable, but offhand, I do not know how to calculate how many layers thick the walls would need to be for what size balloon to withstand the pressure.

Is it possible that a tiny vaccuum balloon could float in air? I just read that small balloons can be made. Is it possible that a tiny vaccuum balloon could float in air?
