    It's about 200MPa or 30,458 psi which will break most materials.

    A diamond anvil can easily contain it though and allows many weird phases of ice to be studied such as ice II which exists inside Jupiter's moons.

  • Ive always wondered why iron chemistry has been so ignored. Its abundant, cheap (free if you have a magnet) and has wonderful chemistry.

  • I wonder if people use this technique for timed bombs.

  • very cool demo!

  • So, if the water was put into the iron ball at 4 degrees celsius and then rapidly cooled, the explosion would've had more force, as it would expand faster/more?

  • it's ethanol with piece of dry ice dropped in, giving off the CO2 bubbles

  • You are right though.  That is the reason.

  • Not quite. Water contracts until it is cooled beyond 4 degrees celsius. Then is begins to expand as its temperature decreases. In other words, in 1 atm pressure, water is at its smallest volume when its temperature is 4 degrees. If it gets hotter or colder, it expands.

  • I think so

    Who knows...

  • so you're saying the expanding power of freezing water is infinite?
