] We report a reversible liquid-solid transition upon
] heating of a simple solution composed of a-cyclodextrine
] (alpha-CD), water, and 4-methylpyridine. These solutions
] are homogeneous and transparent at ambient temperature
] and solidify when heated to temperatures between 45° and
] 75°. Quasielastic and elastic neutron scattering show
] that molecular motions are slowed down in the solid and
] that crystalline order is established. The solution
] "freezes on heating." This process is fully reversible,
] on cooling the solid melts. A rearrangement of hydrogen
] bonds is postulated to be responsible for the observed
] phenomenon.

...Dude.

[ seriously. that's crazy. -k]

A Liquid that Goes Solid when Heated
