Mechanized Dinosaur. With the promise of $2,000,000 from the Atomic Energy Commission, Alvarez and his team went to work on a chamber 6 ft. long. The difficulties became fantastic. The electromagnet surrounding the chamber had to weigh 200 tons. The great machine had to be movable, but wheels were too unstable. Instead, it was given four massive feet on which it could be walked around like a mechanical dinosaur. Leak detectors were installed everywhere to watch for escaping hydrogen; 104 alarm circuits inside the machine flash lights, ring bells and honk horns at the slightest hint of trouble...
...Lawrence calculated that they could be made to whirl progressively faster in a closed chamber, reaching great speed and high voltages. They could then smash atoms and transmute elements. He first demonstrated this phenomenon with a crude but spectacular Rube Goldbergish kit: a kitchen chair, clothes tree, 4-in. electromagnet, pie-sized vacuum chamber made of glass, brass and sealing wax, all put together for $25. When he hooked this odd gizmo up to an ordinary electric socket, atoms whirled around faster than those emitted by radium...

An attorney who had learned that his opponent planned to introduce into court the tape recording of a secret meeting carried a powerful, battery-operated electromagnet into court in his briefcase. He placed his briefcase near the opposition lawyer's tape. The magnet erased the recording, left the rival attorney with a blank tape and blank expression when he got up to play the evidence...
