The October stories at the main Flying Circus of Physics web site include (1) seeing the shock waves of large explosions, (2) the dynamics of playing cards, leaves, and helicopter seeds (samaras) during falling (appropriate for the falling leaves here in Cleveland this month), (3) the physics of two hoax videos that went viral recently (liquid mountaineering and catching a melon with your face), (4) the pub trick of the month --- picking up a drinking glass with a straw, and (5) my old article about the strangest illusion I’ve ever seen --- Bidwell’s ghost, with which I can “read” a page in total darkness.
