One day a man with an engineering background came to see Sisman Tuccar at the teahouse. He said, “This thing that’s between what’s already gone and what hasn’t yet arrived, sounds very interesting to me. Can you explain to me how it works?”
“It’s really simple,” replied Sisman enthusiastically, “it’s like one of those popcorn machines you get at the fairground. When you plug it in, popcorn comes out.”
