-Glass Aquarium Hood (or an acrylic tank if you have one will work on its own)
-Clear Aquarium Silicon (or epoxy)
-Aquarium Light Fixture
-Knob Pulls, or handles (or similar.. like candle holders)
Attach the knob pulls (the ones in the photo are the SATTA acrylic knobs from IKEA) to the light fixture using the silicon and allow to dry. Place the fixture on-top a flat glass top aquarium lid or an acrylic tank. For the blue-ish glowing effect you'll want an LED aquarium light fixture, otherwise try a light fixture that takes regular aquarium bulbs and opt for the color coated ones (blue, red, etc).
A few handle options... 1, 2, 3, 4, 5, 6, 7, 8
