It is a stubborn myth that rubber tyres insulate a car. They do not: a discharge that can cross kilometres of air ignores a few centimetres of rubber. What protects you is the metal body, which carries the current around the cabin and into the ground, the Faraday cage effect. A convertible or plastic-bodied car offers no such shield.
Cooled below −183 °C, oxygen turns into a pale blue liquid. Pour it between the poles of a strong magnet and, instead of flowing away, it hangs suspended between them. The reason lies in its unpaired electrons, which respond to the magnetic field. Liquid nitrogen, by contrast, is colourless and pours straight through.
In 2012, Felix Baumgartner jumped from a capsule hanging beneath a balloon, about 39 kilometres up. In that extremely thin air almost nothing slowed him down, and he reached around 1,358 km/h in free fall, or Mach 1.25. He became the first person to exceed the speed of sound with nothing but his own body.
