Hey guys - do you like card trick videos with a bit of maths? Do you want more? Thumbs up so I know whether to shoot more!

Lol, it really feels like he doesn't want to reveal his secrets. :P

Here's my slight variation on this trick:

If N1 < N2, put the second "fail" card on the bottom before counting the difference.
If N1 > N2, put the whole second pile underneath as Matt did.

That way you can be consistent with how you count the cards (always turn over the Nth card, instead of counting N and then turning over the next card).

If they pick an irrational number, punch them and take their money.

"and then their brain blows up" 😂😂😂😂

[mismag]

Brady, it looks like people want more MATHS CARD TRICKS :)

[numberphile]

great - thank you!

more like this one are coming!

I've never seen someone so enthusiastic about magic.

"Really? Im glad you're certain because it is the top card!" "and then their brain blows up"

Nice. Covered all of the possibilities. I like the MIT  (Magician In Trouble), syndrome. This effect is a great follow up after an ACAAN (Any Card At Any Number), effect where the effect is carried one step further (if it ever comes up that the spectator is sceptic of the first effect ), by allowing the spectator to pick the number where the card should be in a sense that you sent the number to the spectator, yet leaving the spectator with the thought that the spectator really received the number that you sent or the spectator could have picked any number that popped in their head. This is perfect when the spectator is sceptic that the performer is really not sending the number to them mentally and the spectator just say any number to see if the trick will work. So, when the effect still works, in that case,  this makes the effect all the more powerful!

I'm really excited about the Rubik's cube videos! I've always been fascinated by those things, and any discussion about them from you guys on Numberphile is guaranteed to be amazing, and probably even mind-blowing.

This is a mechanic that can easily be added onto to involve audience members picking the card. Add a little sleight of hand into the equation and you can really make a brain-teasing trick that's guaranteed to baffle people. Not many magicians actually mix sleuth tricks with math tricks, but when it's done well, it's really good.

I like how he was like 'Hey! You're still here! What more do you want?"

[DejanMaticnaLSDu]

I hated math my whole life, I can't stand one day of my life whit out numberphile since I have discovered it. Thank you numberphile for showing me the beauty of math!

1:31 How to fold up a paper *properly* 😆

[presto]

Don't do the failing twice thing. Just ask for a number, deal, ask for another number, deal, then show that they found the card. Failing twice makes it looks like you are just going to keep going until you finally reach their card

[numberphile]

we're doing a bunch of Rubik's videos but they are not quite finished yet...

[kevin]

You should do more videos with Matt. He's pretty cool and funny!

[mismag]

Some of the related videos are pretty cool ;)
