Tatra Tea

A slovak strong liquor known to cause teleportation and time-skipping capabilities on unsuspecting foreigners, usually followed by confusion, strong headache and nausea. So far no scientist was capable of harnessing its power to teleport to a specific point in space and time.

I told that British guy that the bottle of Tatra Tea is 144 proof but it was no point. He vanished into thin air and was next seen 2 days later, somewhere around the hotel lobby confused and begging for water.
