    you can make a fan sort of thing which has a rod and copper wire on the rod in the form of a coil. the two ends of the coil can be attached to aluminium foil on the rod. make the fan move horizontally by pouring water from the top.if 2 wires are made to touch the aluuminium foil on the rod when the fan moves electricity is produced. to check for electricity, the wires touching the alluminum foil can be attached to a bulb.
