Anything scientific peaks my interest and these Mad Scientist Blocks by Xylocopa Designs are no exception! As soon as there's a wee one in the house, they'll be out on our floor for sure.
I also recommend the Curious Expeditions blog for furthering your knowledge of the unusual and noteworthy.
Tonight I've read about Painless Parker, the touring dentist with a bucket full at every tooth he ever extracted. He traveled in a covered wagon from town to town with a P.T. Barnum ex circus manager as his guide who created a noisy ruckus with show girls and buglers who covered up any sounds of pain from patients so that Parker could keep his legally changed first name accurate to his business.
I heard the tinkling sounds of one of only 12 known Polyphons from the Musical Wonder House.
I was also intrigued by the story of Bob Diamond, a 19 year old Brooklynite who heard tale of a secret tunnel under Atlantic Avenue and went off to search for it. It purportedly held the body of a British man, the lost diary of Jon Wilkes Booth and Persian Vampires, according to H.P. Lovecraft. After a year of research and a renewed sense of adventure from seeing the opening night of Indian Jones, he found an unmarked manhole on Atlantic Avenue and crawled into a long forgotten tunnel, which you can now take a guided tour of next time you're in Brooklyn.
I finally stopped reading after the Compendium of Libraries around the world, but I'll soon be back for more Curious Expeditions.
