To be this week's winner, I'll need the name of the material and what it was first used for.

macguru, you're getting warmer.
Lawman, it can be used as an insulating material.
JonB, I'm having problems too. Finding funny pictures isn't my forte. (I propose an independent body to procure and administrate funny pictures for each upcomming Gizmo quiz).
Oh yeah, you're partly there but not there yet. I'm still waiting for the full answer.
Made from a maze of silica strands only one one-thousandth the thickness of a human hair, the substance is 95 to 99 percent empty space and weighs only three times as much as air, yet a one-pound block can support half a ton.
cmon, isnt this close enough?

Mixing four chemicals, which react to form a wet gel, similar to a gelatin dessert creates Aerogel. The gel is then dried in an autoclave, in essence a pressure cooker that applies pressure and heat.
What is it used for?
Aerogel was first made in the 1930s by Samuel S. Kistler, who obtained several patents for making a variety of aerogel, including silica, alumina, chromia, tin and carbon.
i mean it cant get any closer than this!

Aerogel is the result of a friendly wager between Dr. Steven Kistler and Dr. Charles Learned, two Stanford University scientists. They competed to see if one of them could replace the liquid inside a jelly jar with gas without causing any shrinkage. Kistler won the bet, and published his findings in a 1931 edition of the journal Nature.
well, in that case. since i had NO IDEA what this could be i searched for what OTHER is in the picture. went to google image search. searched for "hand". 400+ results nothing.
then i tried "hand holding" and in page 4 there it was. when i saw this my heart started +50 and windows got unstable. could not get WebmasterWorld to work.

since this was pretty mcuh all except whrn it was FIRST used, so i started on google search for term "first used".
