Why Toast Lands Jelly-Side Down

Physics has the reputation of being difficult to understand and remote from everyday life. Robert Ehrlich, however, has spent much of his career disproving these stereotypes. In this sequel to "Turning the World Inside Out and 175 Other Simple Physics Demonstrations", the author presents a new collection of physics demonstrations and experiments that prove that physics can, in fact, be made simple. Intentionally using "low tech" and inexpensive materials from everyday life, the book should make key principles of physics easy to understand. After laying out the basic principles of what constitutes a successful demonstration, Ehrlich provides more than 100 examples, including "Terminal Velocity of Falling Coffee Filters", "Spinning a Penny"; "Dropping Two Rolls of Toilet Paper"; "Avalanches in a Sand Pile"; "When to Add Cream to Your Coffee"; "Deep Knee Bends on a Bathroom Scale"; "Recoil Force on a Bent Straw"; "Swinging Your Arms While Walking"; "Estimating the Net Force on a Moving Book"; and "Why Toast Lands Jelly-Side Down".
