Soory class, I got caught up in things, then a family visit, then a surprise bouquet of flowers, then dozed off after dinner!
Wila, glad you like your puzzle. ?I'm sorry that things are very difficult in the US just now. it must be quite scary for you. ?
Thank you all so much for cheering me up with your inventive solutions to the riddle.
The official solution to the poison riddle is:
The poison from the punch came from the ice cubes. When the man drank the punch, the ice was fully frozen. Gradually, as the ice cubes melted, the poison was released into the punch.
Thesolution is in the question. Everyone who subsequently drunk the punch, was poisoned Nothing about eating food etc.
This is harder work, than when I was a actually teaching! .
Hope to see you all tomorrow.
