Fly in a glass

The object is to move 2 matches to get the bluebottle to fly outside the glass. At the finish, the glass may be turned in any direction, but it must be exactly the same shape as before.


Just move the horizontal stick to the left by half width. And right vertical stick to the bottom left to get the glass turned upside-down.
