Dr. Helen Maynard Casley, (one of) THE principal scientists at ANSTO (Australia's Nuclear Science and Technology Organisation), sets Kovi's and Benjamin's brains alight as she talks about working on the Wombat (not an acronym - Australians just like naming things after animals). Wombat is a high intensity neutron diffractometer that Dr. Helen uses to just scoop some neutrons out of a working nuclear reactor. You know, for kicks! You'd think that line of work would make someone glow, but not so! The reason she glows - or glowed - was when she helped set the Guinness World Record for longest glow necklace!
