I shudder to think of the paperwork the EU would require for authorization to transport antimatter off-campus. But they have hauled it around for up to 20 minutes (https://www.antimatter.hhu.de/en/about-us/base-step) so in principle it could go a bit farther!
Now I'm imagining Klaus driving around with just a bit of anti-matter.
