I've noticed that hydrogen when cooled to two degrees above absolute zero can be pushed through a tube at higher pressures than any other liquid on earth. In fact, they tend to exhibit near no friction forces on the tube they pass through. I'm going to research this idea further.

But, there are so many types of liquid explosives, and considering little research has been put into it, there are still so many things we have not even looked into as of yet.
