MICHIO KAKU in his book  "Physics of the Impossible”


Totally true story.

“In high school for my science fair project I assembled an atom smasher in my mom’s garage. I went to the Westinghouse company and gathered 400 pounds of scrap transformer steel. Over Christmas I wound 22 miles of copper wire on the high school football field. Eventually I built a 2.3 million-electron volt betatron particle accelerator, which consumed 6 kilowatts of power (the entire output of my house) and generated a magnetic field of 20,000 times the Earth’s magnetic field. The goal was to create a beam of gamma rays powerful enough to create antimatter.”
