balloon by falk starke from germany

a helium ballon as a ceiling lamp. a led sits in a gondola unterneath the ballon which reflects the light. a sudden pull at a small ball at the end of a cable works a switch. inside the small ball is a capacitor, you charge it inside an induction-coil which you plug in a wall-socket. the coil creates a magnetic field that holds the balloon down. it is now a standing lamp.
