Unfortunately, we weren't able to get any to explode at 12V.

It's hard to make LEDs explode. I connected them to 90V DC and they would just burn out. We had to use 230V AC to make them explode.

Also, the resistance of an LED changes based on how much current it is using, so you'd have to figure out that value as well if you planned on running them at something other than 20mA.

You don't need to know it. LEDs have a resistance but it's not important. You just substract the voltages and use the ohms law for the resistor.
