Coin Butterfly

by Peter Grabarchuk

Five identical coins are arranged into the shape shown in the illustration. As it can be seen centers of the coins lie in the vertices of two identical equilateral triangles shown with the dotted lines.

Make only two single-coin moves and create two different equilateral triangles instead of these identical ones. A single-coin move consists of sliding a coin to new position where it must touch at least two other coins.
