hi iiiiiiii iiiiiiii
Simplified version of this:
Get a bulb or clear bottle, pour water inside as it creates a magnifying glass-like effect. Get a torchlight. Balance the torchlight and let it face the bulb/bottle at a close distance and use a thick material to prevent the light from the torch from escaping into the background before it hits the bulb/bottle.
Whatever image is between the bulb and the light gets projected unto a surface adjacent to the light source.
Voilla.
