I imagined sending him up to the international space station for charity. He could go up on one of Elon's rockets that doesn't explode. Then the crew would try to bow their heads but end up spinning around because of the lack of gravity.
Then he could squirt some Crème Brulé and champagne into his mouth for lunch; I don't know what the royal family eat for lunch. Perhaps he could do some experiments up there.
A charity space quest for the king 🤔
