Poly(methyl methacrylate), or plexiglass, was found to react to ethanol when used in high concentrations.  When our fiber bending tank (made of poly) was being cleaned with pure ethanol, an obvious reaction was seen as crazing developed on the surface of the walls of the tank.  Because our fibers are made from a similar material it seemed necessary to also test their reaction to exposure to alcohol.

Two different alcohols, ethanol and propanol, were measured out and mixed with tap water to create different concentrations.  In the first 5 vials were concentrations of ethanol, the next five were concentrations of propanol, and in the last vial was tap water only.  The fibers destined for the vials were cut, measured cross-sectionally and lengthwise, and weighed with a milligram scale.  Both scintillating fibers and lightguides were tested.
