22 Karat Gold Billboard

We wrapped a billboard in real 22 k gold to promote Science World’s Treasure! exhibit, and to dramatize this scientific tidbit: a mere 2 oz of gold can be hammered so thin it can cover a whopping 200 square feet.

The first of its kind, the golden board sparked a media frenzy. It took weeks of painstaking work by Canada’s top gilder Brian Dedora and required a full-time security guard to discourage theft and damage.

Only a handful of passing motorist were permanently blinded, but hey you can’t make an omelette without burning a few retinas, right?

(Totally kidding about that part.)
