Petroleum by Max Lukian

A selected card is signed and lost in the deck. The cards are shuffled face up into face down – and shown to be completely mixed on both sides. Without ANY funny moves, you instantly spread the cards and show they are all now facing the right way… except for their signed selection!
Petroleum is that clean and that fast! It happens in less than a second.

But it's MUCH more than just a triumph effect. It can also be used to perform a stunning version of Oil & Water, in which face up and face down cards separate from one another – starting with just a few cards and ending with the full deck.

Each Petroleum set includes a custom Petroleum deck and over an hour of expert video instruction by creator Max Lukian. You'll learn multiple handlings of every routine, as well as Max’s favorite use of the Petroleum principle: a dual-reality triumph. Diabolically crafted, it’s the strongest piece of card magic Max performs – and now it’s yours!
