How to Hollow Out a Lightbulb and Make a Stand for It

for other uses like plasma globes and aquariums

for this you will need;

lightbulb (preferably burnt out)
scrap wood block
wire hanger
salt

tools;

wire cutters
duct tape (or stapler or staple gun)
drill

use pliers to pull off the brass contact

then use pliers to chip away the black glass

drill the inside of the glass to remove the filament thing and remove sharp glass

empty out the shards

put a spoonfull of salt in the bulb, cover the opening with your thumb, and shake

empty out the salt, fill halfway with water, cover the opening with your thumb, and shake

cut a long piece of wire from the hanger

wrap the end of it it around the screw on the bulb

about two inches from the bulb bend the wire down 90 degrees

five or six inches from that bend bend it to be horizontal then two inches from that bend it right 90 degrees

staple or duct tape it to the board

the stand is strong enough to hold the bulb when it's filled with water

you can put a guppie or feeder fish in it (picture soon, i have to find it)

this site gave me the idea for the bulb (and has better pictures)
