The fog generator built into the rock that levitates above the lake turns on when you place a stone on top. The stone and the rock have built-in Pogo pins that are used to turn them on. The rock has built-in LEDs that light up the crystals. There is also a small waterfall. A miniature 5V pump is used to power the waterfall.
