There is a myth that we use only 10% of our brains, and while this is not true, there is no doubt that a trained mind can perform tasks that ordinary people may find miraculous. In his 25th Fringe, Edinburgh magician Ian Kendall will be demonstrating feats of mental agility that will boggle the mind, bamboozle the brain and leave you wondering whether there are any practical applications for this particular skill set (spoiler alert: no, not really). Oh, and there will be magic tricks as well. Sleight of hand king (Sunday Times).'Highly entertaining' **** (Scotsman).
