In each of the two videos below, 9-year old Ian appears to be doing magic but then, just a few seconds later, he shows you what he's really doing. My challenge to you is to ask if you can work out what's going on before it's shown to you. (My brain wasn't quick enough in either case!)
BTW: In case you think that young Ian can't do 'proper' magic, here is with a variation on the classic "Pick a card, any card" trick.
The cameraman selects a card, which is replaced in the pack. After Ian has shuffled the pack, he takes a card at random (stressing that randomness to the cameraman). Then, with a wave of his hand, that card magically transforms itself into the one that the cameraman selected. This time though, like a true magician, Ian doesn't reveal how it's done!
