I have the vacation again

This week I have the last part of my annual vacation. And I spend it, as usual, with my family in the country house.
A time ago my son has been gotten interested in cards. There is a special hobby called ‘Cardistry’. That term was created from two words - cards and artistry. That means the art of card performance. My son asked for me to buy him the hi-quality pro cards by US company Bicycle. They have plastic layer on each card and very beautiful card backs. And there are some special packs for tricks. For example, there are cards with two backs or two faces, or two packs different colors or even blank faces.
When I’d come to the country-side I brought two packs for my son. My son every day trains with cards for a few hours. He watches videos on Youtube and tries to repeat different tricks. He has learned several ways to shuffle packs with one and two hands. The first thing he has learned was the effect of appearing a card in his hand. I, in theory, understand the card is somewhere already in his hand, but I can’t see it as I try and it does the trick very impressive. The last thing he showed me today was, as he called it Hot Shot when he flicks a card from the deck and it flies spinning on the air and my son is catching it down with his other hand.
