My first ever reddit exchange and my gifter nailed it! I received a fantastic book that catered to my science/nerd/geek profile and something that catered for my kids too which were mentioned a few times in my profile. This is a book about the elements and it includes many examples and pullout extra's to keep your interest. There is a sliver of gold leaf, a cubic zirconia, some silly putty, a personal letter from Einstein to Roosevelt and dozens of other post cards pictures and interesting elemental samples. The text is quite technical but the kids are enjoying learning about an element each night before bed. Thanks you very much, I'm hooked on Reddit Gifts now.
