## Description

Glass tubing is most often used in laboratories, but is also very popular for creating homemade Hummingbird feeders. This tubing is of a low expansion borosilicate composition with high chemical resistance, making it the most popular type of glass in the world for laboratory use. It meets all U.S. Pharmacopoeia specifications for type 1A glass. Borosilicate glass is simply the generic form of the better known heat resistant glass brands Pyrex, Corning, Simax, Kimax and others.  In order to be bent, the tubing has to be heated until it glows a faint red color. Heating should be with a propane or natural gas burner similar to a plumbing torch or our propane Bunsen burner. Propane can be purchased at a local hardware store.

    I can't remember why I bought this
  

*by C***U on Reviewed in the United States on September 26, 2013*

I think I bought this because I was trying to learn glass working, but I got distracted and totally forgot about it, storing these away in a forgotten drawer. Months later, a friend of a friend with a serious drug problem was crashing at my apartment overnight, and went through everything I owned while I was sleeping and discovered these, as well as a blowtorch. I woke to some confusing sounds, and when I went out to investigate, I found the kid working these glass tubes with a blowtorch. Long story short, he'd worked them into zig-zag shapes and had somehow decided to use a blowtorch to heat up the bottom of a borosillicate glass tube and snort copious amounts of instantly-vaporized-by-the-heat-drugs into his face. While I never had a chance to use these myself, I can report that some tweaker kid found them to be extremely useful, and they made a wonderful shattering noise when I smashed them on the pavement the next morning.Pros: even people on drugs can work these into unusual shapesCons: I forgot what project I bought these for in the first place
