Police are investigating a school in Shanghai after it failed to live up to its promise of teaching children special powers. Dozens of parents fell for the ruse, enrolling children . . . in the summer course at £9,950 (100,000 yuan) a head. Among the special powers . . . to be taught was the ability to read a book in 20 seconds and identify a poker card with the touch of a hand . . . [and] see the answers to exams in their heads on sight of the test paper. This remarkable feat . . . would be achieved by tapping into the right side of their brain. This would enable the children to detect ‘waves’.
