Aliens
I invented a spoon for Aliens - although I don’t know any to test them on. But actually Aliens are just those around us who we don't entirely understand. Like Antivaxxers, Flat earthers, Climate deny-ers, even Politicians.
Alien as their weird ideas are, they’re all still, arguably, humans. Humans are Homo Sapiens.
But Homo Sapiens Sapiens is the sub-species that evolved even further that includes me - and maybe some of you. For one thing we tend not to believe in the existence of Witches, Homoeopathy or Gwyneth Paltrow but we do believe in peer reviewed science.
Anyway back to the Alien spoon. This particular spoon is uniquely useful to one nasty species of Aliens, namely Daleks.
