50,000 Anti-Hydrogen Atoms hanging on the wall...

...and if one should fall it would mutually annihilate an equivalent number of particles.

From the AIP's always interesting Physics News email newsletter:

"COLD ANTI-HYDROGEN ATOMS have been made, stored, and detected for the first time in an experiment at CERN. The ATHENA collaboration makes the anti-H atoms when a swarm of antiprotons is loosed upon a cloud of positrons held within the same 16-cm-long cylindrical trap."

It takes a lot of energy still, and there are storage problems, but this means that it's another step along the road to usable antimatter creation techniques.
