[Editor's note: the lightbulb can break during
construction - wear gloves! Glass straws are highly
advised, as plastics can emit harmful vapors]  There are a lot of really expensive
vaporizers available, but there are cheaper ways? This
might not work as good as the $200 ones, but it does
work well. Parts list:
Normal light bulb (100 watts if possible; the glass
is more heat resistant than 40/60 watters. The bulb
should be clear and not frosted)
Knife
Scissors
Tape
2 straws or glass tubes (glass tubes are better
since they can't melt)
Cap of a 0.5 liter bottle (US: 16 fl. Ounce bottle
cap)
Construction:
First if all, we
start off with preparing the buld by cutting off the
lower part like this:
 You
might want to sand off those nasty metal edges since
they are really sharp, like this:
Now, in step 2,
we need to get the wire and all that out: (Remove them
either with a small wrench or break them out with
something else like a pair of pliers)
 In
step three, unscrew the cap of the bottle, and try to
fit it on the metal part of the bulb, if it doesn't fit
because it's too small, get another cap, it's ok if its
too big. Now take a knife and make two holes into the
cap, like this:
Now
we have to make the straws the right size, take the
scissors. If you are using glasstubes, take a wrench to
break them at the right point, and take fine sand paper
to make the edges smooth.
 If
the cap is a bit too big, just take the tape and fix it.
Even though its easy to do this, every time you want to
fill or empty it you have to tape it again. So try to
get a cap that fits! There is another way you can tape
it, like this, that's easier:
 Before you use it for the first time take cold
water and wrinse it out, glass and dust might be left
inside, and you don't want that in your lungs....DONE!
To use it, unscrew the cap, put whatever
you want to smoke inside (careful, you don't need as
much as you need in a normal joint), take a lighter or
candle and heat it, inhale, and when you taste
something, its working.
Don't wait until it smokes,
because that will leave stains. In the best case, you
will take out the weed, for example, looking just like
you put it in, but smelling like hay after you are done.
 Here is a version with one glasstube instead of
a straw, and how it actually looks when being used.
Thanks DoobieScoo.

There is, I believe, a way to make it better:
While most of the vapor created is kept inside, I was
still losing vapor. This was my fault as I did not tape
the cap on as suggested. After a bit, I made some
modifications, and found that not only was it easier to
use, but it worked quite a bit better as well.
I
took the bottle that the cap came from (a US 20 oz
bottle), and cut it off at the neck, so that the cut end
of the upper portion (the part with the thread for the
cap) would fit well over the screw part of the
lightbulb. I then hot-glued (though duct tape works) the
top portion of bottle onto the light bulb do I could
screw the cap on and off.
 The first pic shows the unit assembled. The
duct tape does not actually hold anything on, it is just
insulation against the glass; it makes a good handle.
You can make out the hot glue I used to put the bottle
end onto the cap. It has just been used and is dirty.
 The second pic shows the cap
unscrewed. You can see the threaded part of the bottle
attached to the bulb. You can also see that I used a pen
as the intake tube and two straws as a mouth peice. When
you end the moutpiece tube as far up as I have, you need
a filter to keep particles out. I used a nylon mesh (the
kind on a screen door/window). All of this is sealed
with hot glue (although duct tape works well too, I just
had a glue gun around the house so I used it)
 The third pic is a close up of the cap
assembly. You can clearly see where the bottle has been
attached, on the cut portion of the bulb, on the right
of the duct tape, with hot glue.
 The fourth pic shows you where I cut the
bottle. I cut it larger than needed, and cut it down to
size after (much easier that way).
