for other uses like plasma globes and aquariums

Step 1: materials

for this you will need;

lightbulb (preferably burnt out)
scrap wood block
wire hanger


wire cutters
duct tape (or stapler or staple gun)
<p>Put salty water in the bulb and put it back together.</p>
<p>Put salty water in the bulb and put it back together.</p>
considering this type of bulb is illegal to manufacture in the US now some one should consider making and selling pre hollowed out ones for doing crafts like this cause the new spiral kind wouldn't be the same
When you mount the wire to your block of wood, simply drill a hole slightly smaller than the diameter of the wire and use a grommet for a finished look. Nail polish will hold it permanently. I used them for money plants, the roots look cool.
i want to say thanks for this instructable. the whole hollowing out a lightbulb was a pain for me until i found it. i emptied my bulbs for the hourglass i made. it was prettyy fun.
Very, very cool!
that is freakin sweet
how long does the hourglass go? as in time<br />
about twenty five minutes. and 37 seven seconds. depending on humidity lol<br /> <br />
That is really cool - creative and it looks good. Great job!<br />
That's cool!
You should post an instructable on how to make it!
cool idea
Awesome! Thank you for sharing.
How about a sea monkey aquarium?
I choose the gifts from myloveedhardy.com. It&rsquo;s really a good choice.
What's the salt for??
salt removes the &quot;Soft White&quot; coating from the inside of the bulb. Basically the salt acts like a media abraisive. Meth addicts around the world use this technique to very inexpensively create a &quot;Pipe&quot; so if you've got teen age kids, this may well be a good way to catch them in time to get them treated.
Unfortunately though many people <a href="http://www.cheap-uggs-boots.com/sundance-ugg-boots/" rel="nofollow"><strong>UGG Sundance</strong></a> are told to avoid the wrong thing - they are told to avoid sugar when the real culprit is fat.Fat, unlike sugar, is very hard for the body to digest. This means it can take substantial amounts of time to digest - up to <a href="http://www.cheap-uggs-boots.com/sundance-ugg-boots/" rel="nofollow"><strong>Sundance ugg Boots</strong></a> 24 hours or more. As a result it stays in the blood and can interfere with other foods you eat especially sugar. When you eat sugar after eating fat, the fat in your blood will prevent the sugar from moving through the blood to starving cells. This makes your blood sugar levels rise and <a href="http://www.cheap-uggs-boots.com/sundance-ugg-boots/" rel="nofollow"><strong>Sundance uggs</strong></a> this is a dangerous. Luckily the body has systems in place to combat situations like this. An organism found in the body called Candida helps out in this situation by eating the sugar which makes it multiply and bringing <a href="http://www.cheap-uggs-boots.com/sundance-ugg-boots/" rel="nofollow"><strong>ugg 5325</strong></a> down the sugar levels. If you always have a high fat diet then you will always have a problem with Candida in that the organism will be about <a href="http://www.cheap-uggs-boots.com/sundance-ugg-boots/" rel="nofollow"><strong>ugg 5325</strong></a> in high levels. However high fat on the odd occasion should not be a problem.
instead of drilling into to the end of the bulb, use a hammer to break the black glass cool instructable!
This is very cool!&nbsp; I'm going to try to combine it with this idea as a novelty gift:&nbsp; http://www.flickr.com/photos/teamdroid/487588642/<br />
Nice. You could do something really ironic like save the contacts and all the stuff and fill it up COMPLETLY with gas, and if no oxygen was dissolved, and it was all sealed up, you could screw it in, turn it on, and it wouldn't explode... maybe... DO NOT DO THAT. I AM NOT RESPONSIBLE IF YOU DO. I may just use them to make abstract art... I like the fish idea...
A) ... how. B) why C) natural gas? dead. gasoline? would short out, gasoline needs a specific air/gas ratio to combust
&nbsp;ALL fuels require a certain air/gas mixture. &nbsp;Natural Gas (methane) is 10:1 feet cubed with atmospheric air, and 2:1 pure Oxygen.
Well, I don't know what I was thinking a year ago... And I guess I couldn't spell "sense" either...
Boy my comments didn't make much sense a year ago...
Your comments <em>never</em> make sense....<br/><br/><sub>(Just kidding).</sub><br/>
How <em>dare</em> you insist that my speech is coherent!<br/>You're so mean D:<br/>
&nbsp;May I insist that your <em>math </em>is coherent?&nbsp;<br /> cause last time I checked &quot;2006&quot; and &quot;2008&quot; is 2 years correct? lol,&nbsp;<br /> <br /> Either way caution as lightbulb gas molotovs may just be the new thing! =D<br /> <br />
little bit of fight club, no?
Wow, that made no sence...
Neat idea! look what I found, it seem to be a cleaner tecgnique of removing to end of the bulb : http://www.instructables.com/id/Incandescent_Lamp_Hack/<br />
Holy cow - I&nbsp;love this!!<br />
nice. thanks for sharing.
this is what i made<br />
That is really cool as well! Great job - I love the creativity of the people on this site.<br />
this totally isn't meant for making a vap or anything... :p<br />
ya i totaly just figured ... put a candle under it
is it really a good idea to put fish in it
I asked a fish, he doesn't like the idea at all.
or to use as a survival fishing float/bobber
If you have enough time on your hands, you could also make these into LED lights.<br/><a rel="nofollow" href="http://www.thinkgeek.com/gadgets/lights/7aa8/">http://www.thinkgeek.com/gadgets/lights/7aa8/</a><br/>
thinkgeek rocks!
w00t :thinkgeek rules
why use LED's, bulk buy glow sticks, chop the tops off them, then pour the liquid in to the bulb you just gutted. then add the liquid from the glass tubes (from inside the glow stick) one at a time so the bulb lights then when it gets dim add another tube, it would last for ages. There would also be a mix of colours.
:-X EKKK!!! BE VERY CAREFUL!!!! They put lead on the bottom of the bulb, and fill the bulb with MERCURY VAPORS!!!!! + other bad stuff!!!! BAD!
actually the bulb has a vacuum in it and lead isn't really poisonous.
