Lumps of gold moulded into rings, coins and ingots have been highly prized for millennia. But recently, scientists have realised that tiny pieces of this precious metal – far too small to be seen by the naked eye - could also become a valued commodity. In labs around the world, gold nanoparticles are being tested as components in technology and medicines. See how gold could be used to kill cancer cells, improve the efficiency of solar cells and catalyse chemical reactions. (5:17 min)
"Exploring Materials - Thin Films" is a hands-on activity in which visitors create a colorful bookmark using a super thin layer of nail polish on water. They learn that a thin film creates iridescent, rainbow colors.
