Dutch artists Milan van de Goor, who was previously featured on this blog, and Lynn van den Berg conducted this beautiful experiment. They started with a leaf on top of a plate of milk and then introduced spray paint to the equation. They observed that the spray paint actually floated on top. As it dried, a film formed, which they took advantage of by adding multiple layers. When they pulled the stem of the leaf, the now elastic, dried layers of spray paint separated, revealing multiple levels of beautiful color.
