Chemistry is full of facts that seem too strange to be true. Here is a collection of weird chemistry facts.

  • Liquid oxygen is blue.
     
  • Some radioactive elements really do glow.
     
  • You can die from drinking too much water.
     
  • If you mix half a liter of alcohol with half a liter of water, the volume of the mixture will be less than one liter.
     
  • Liquid water is more dense than solid water (ice).
     
  • You can melt a sample of the element gallium just by holding it in your hand.
     
  • Under certain conditions, hot water will freeze more quickly than cold water.
     
  • You can't solidify helium at normal pressures, even at absolute zero. (You can solidify it at extremely high pressure and low temperature.)
