Step 1: Extract The Lamp Fixtures
Find an old lamp (I used a lava lamp) and using whatever means necessary, pull out the electrical pieces without damaging them. You could probably go buy these parts but what's the fun in that?
Step 2: Detach The Wires
Loosen the screws on the electrical piece and pull out the wiring.
Step 3: Find A Suitable Lamp Body
I used a pot I bought in Arizona but you could really use anything that's large enough, has a satisfyingly large hole to work with, and is easy enough to drill through.
Step 4: Drill A Hole In The Bottom
It should be large enough for the bottom part of the lamp piece to fit into.
Step 5: Drill A Hole In The Side
It should be large enough for the wire to fit through but not too large.
Step 6: Push The Wire Through The Hole
Pull it out of the top of the pot (or whatever you're using)
Step 7: Reattach The Wires
Just place the wires back into position and tighten the screws holding them in place.
Step 8: Add Glue To The Bottom Of The Electrical Piece
Don't drown it in glue but don't be skimpy.
Step 9: Put It In Position
Place the lamp piece on the bottom of your lamp body so that the small screw-like part aligns with the hole on the bottom. Hold it for a little bit and let it dry.
