Form a metal alloy as bismuth and tin are heated to the eutectic point of the two metals which is lower than the melting point of either metal.
Excellent demonstration of thermoplastic polymers.
EdU (5-ethynyl-2’-deoxyuridine) is a nucleoside, an analog of thymidine, carrying an ethynyl group. This nucleoside behaves as a substrate for cellular DNA replication machinery. After EdU incorporation, DNA containing ethynyl groups can be ligated by click chemistry reaction with various dye azides. Fluorescent DNA can be detected with microscopy, or cells can be sorted with FACS.
When water is added to this granular white powder, the polymer instantly expands to 40 times its original volume, producing a snow-like material.
