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?
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.

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.

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

You are right though. That is the reason.

I think so
Who knows...

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