I had a number of ceramic ICs with gold pins in old anti-static foam; ate
the pins right off.

ick! thanks for the tip, will get right on it.
The most egregious use of foam I've encountered was in a token ring
hub, where a block of foam was use to support the small PCB which ran
the width of the hub. The PCB held the relays that sit behind the
sockets, of course with the foam atomized the PCB was swinging around
on the wires.
