Formation by Penguin Magic is pretty straightforward. You start with what looks like a white credit card, give it a squeeze, and suddenly you've got a pair of headphones. Why this fools people as much as it does, I'm not entirely sure, but there you go. The headphones even play music, which is a nice touch. Here's how it goes: Pull out what seems to be a plain white card from your wallet. Turns out, it's actually a flat headphone case. Squeeze it, and it pops into a real headphone case. You can even let people check out the headphones inside. Once you're done impressing, a firm slap flattens it back to a card. It looks like the earbuds everyone seems to have these days and plays nice with all AirPods and some other brands too. The moves are simple enough, though getting it smooth might take a bit of practice. No sneaky bits or magnets, just some clever handling for a bit of visual fun. You'll need to supply your own headphones and case for this one.
