Normally in my wallet I carry some packet tricks, hopping half and Unboattled.

If you want to see what is Unboattled about, take a look:

It's cool to do it when I don't have a deck of cards with me and it's very fun to do.

The good thing of Unboattled is you can give away to the spectator a souvenir of that magic moment.
