Black Lips by Julio Montoro and Victor Sanz ( Instant Download )

Black Lips turns a simple black sticker into a real, physical black hole. A borrowed and signed bill receives a round black sticker… and that sticker becomes a Black Hole through which objects can genuinely pass.

In the end, the black hole collapses back into a regular sticker, and the signed bill is left completely intact and fully examinable without any switch.
