North Korea claims its scientists have invented a potent alcoholic drink - that leaves no hangover.
According to the state-owned Pyongyang Times, experts have replaced the sugar in Koryo Liquor with "boiled and scorched glutinous rice".
The spirit is also made with ginseng and apparently has an alcohol content of up to 40 per cent.
If it actually works, it should mean the end of tigers in bathrooms...
