How to hollow out a lightbulb

I know this had been done before, but the one before had bad images. They were all blurry.

Take something Grainular like sand or salt or something. I used sprinkles because i didnt have any salt or sand.

Put a paper towel over the top and shake like crazy untill theres no more white stuff

Step 6: Rinse and execute

Now fill the glass with water and shake so all the fine particles get out and everything is nice and shiny.
Then use it for whatever you want!

"Take off" doesn't exactly describe what I had to do here: I had to hammer really hard.

I don't know if it was for the german lightbulb I used or for whatever but tapping lightly with a screwdriver didn't do anything I had to use a hammer instead.
 Thank you. very good and helpful.

I got most of the white stuff out with water but i used salt afterwords to ensure there wasn't any left.
why do the sprinkles/sand/ salt? i just ran it under the sink. worked fine.

I just hollowed out my first light bulb. I had trouble with the brass end/black glass stuff cause I couldn't get a good grip on it with pliers so I used a bench vice and kept pinching the end and rotating it till it finally got under the brass and I could pull it off with pliers. Then I used a drill and followed down the one wire on the side till the hole was big enough to get needle nosed pliers in and snapped it all out. I used a burn out larger 3 way bulb, it looks neat. Now what do I want to do with it?

No danger of that here

If the bulb's already clear, do you need to do the sand/sprinkles/etc step?

nope

Yeah, my pictures were REEEALLY blurry. /sarcasm
relax. Your picture at http://www.instructables.com/id/Light-Bulb-Shrimp-Aquarium/?ALLSTEPS were by no means blurry, but these are sharper.
Anyways, your project is about shrimp, hollowing a lightbulb is just a side-show!

anyways, both projects are neat
