2000-year-old superglue

The Romans had it. At Discovery News:

Willer found traces of the superglue while examining a helmet unearthed in 1986 near the German town of Xanten, on what was once the bed of the Rhine.

"The helmet, which dates from the 1st century B.C., was given to the museum for restoration. I discovered the glue accidentally, while removing a tiny sample of metal from the helmet with a fine saw. The heat from the tool caused the silver laurel leaves on the helmet to peel off, leaving thread-like traces of the glue behind," Willer said.

Willer was amazed to discover that despite such a long exposure to water, time and air, the superglue did not lose its bonding properties.

Hmmm... I saved this as a note a few weeks ago, but forgot to record where I originally read it. Anyhow, I thought it was interesting.
