Dear Science: Experiments gone wrong, killer bees and metallic hydrogen

AUT's Allan Blackman joins The Wire again for another week. This week, he talks about a botched lab experiment at a UK university, where two students were given a dose of caffeine equivalent to 300 cups of coffee; a surprise animal that tops the list of the most deadly venomous creatures in Australia; and also about how scientists in the US have managed to create the first piece of solid metallic hydrogen.
