This is a great project to work on with just a watering can and an Ikea Vedum fiber-optic lamp.

All you need to do is saw off the tip of the watering can, cut off a couple of the legs of the lamp, and place the fiber-optic spray through the spout and there you have it! Your very own "Pour Lighting" lamp.
