Every one of y’all needs to petition the designer of the floating lamp, a balloon with an LED base. Fill her up with helium and you’ve got, yes, a floating light. Since the balloons follow all the laws of physics, you can expect them to last only so long before they fall back to the earth.
Probably the best thing I’ve seen in a while, real or otherwise.
