So get this: It's not just the magician who's fooling you. Your brain is in on the trick too. After all, your brain is the jerk that makes you believe that the old dish towel "magically" turned into the dog keychain, which is probably a really popular trick that real magicians perform in Las Vegas. If you want to find out how these "magical" "tricksters" like David Copperfield conspire with your human brain to pull off amazing stunts that they hope will lead them to a life of money and babes and sports cars, then you should check out the "Ask a Scientist" event, The Neuroscience of Magic at the SoMa StrEat Food Park. UCSF neuroscientist Adam Gazzaley and Robert Strong, the Comedy Magician, will perform illusions and then explain how your brain is tricking you into believing that some dude is defying the laws of physics. The StrEat Food Park also features a variety of gourmet food trucks and the city's only beer and wine truck, which sounds like wonderful magic, but is totally for real.
