There is a better way to do this without spending very much cash.

1)Instead of a lightbulb, use a "boiling flask" preferably with a flat bottom, for example this one for $3.50
250 ml Boiling Flask - Flat Bottom: The Science Fair Inc.
250 ml is the perfect size, slightly bigger than a lightbulb
(SEE PICTURE BELOW)

The glass is thicker, pure, it has a flat bottom so you can put it down safely, its unlikely to break, and there is no weird glue stuff to worry about.

2)Get a #6.5 (six and a half) two-hole rubber stopper. This will fit erfectly in the flask above, and gives you a carb hole and a tube hole and its like $.50 and won't give off any noxious fumes or anything. (see picture)

3)if you want to get fancy order a small amount of 6mm glass tubing for your "straw" so that its almost all glass system.

Total cost is less than $5, but its totally clean, not gonna break, all glass, and works great.:thumbsup:
