Well, according to Dave, all you have to do is add a little salt.
This instantly allows whatever system you're working with to violate all laws of thermodynamics. Silly that no one ever thought to try that!
If no one even tried then this wouldn't be possible either:

Fragile particles rarely seen in our Universe have been merged with ordinary electrons to make a new form of matter.
Di-positronium, as the new molecule is known, was predicted to exist in 1946 but has remained elusive to science.
Now, a US team has created thousands of the molecules by merging electrons with their antimatter equivalent: positrons.
The discovery, reported in the journal Nature, is a key step in the creation of ultra-powerful lasers known as gamma-ray annihilation lasers.
"The difference in the power available from a gamma-ray laser compared to a normal laser is the same as the difference between a nuclear explosion and a chemical explosion," said Dr David Cassidy of the University of California, Riverside, and one of the authors of the paper.
As a result, there is a huge interest in the technology from the military as well as energy researchers who believe the lasers could be used to kick-start nuclear fusion in a reactor.
Conventional thinking states that both antimatter and matter should have been created in equal quantities at the birth of the Universe.
The dominance of matter in our world is one of science's most enduring mysteries.
Antimatter only makes fleeting appearances in our Universe when high-energy particle collisions take place, such as when cosmic rays impact the Earth's atmosphere. They are also made in the lab in particle accelerators such as Europe's nuclear research facility, Cern.
These appearances are always short lived because antiparticles are destroyed when they collide with normal matter. The meeting leaves a trace, often as high energy x-rays or gamma-rays.
A burst of 20 million were then focused and blasted at a porous silica "sponge".
"It's like having a trickle of water filling up a bath and then you empty it out and you get a big flush," said Dr Cassidy.
As the positrons rushed into the voids they were able to capture electrons to form atoms. Where atoms met, they formed molecules.
"All we are really doing is implanting lot of positrons into the smallest spot we can, in the shortest time, and hoping that some of them can see each other," said Dr Cassidy.
By measuring the gamma-rays that signalled their annihilation, the team estimated that up to 100,000 of the molecules formed, albeit for just a quarter of a nanosecond (billionth of a second).

Hydrogen annihilation may be possible as well.
