Freeze! by Florian Jenett and Valentin Beinroth…
Over a period of several hours Valentin Beinroth and Florian Jenett placed about 50 handgun replicas in downtown Frankfurt. The guns were made from tinted ice, making them look real at first sight. The two created realistic situations, leaving the replicas behind as if they were lost or dumped. (via)
The Bullet Ice Cubes are also delicious(ly dangerous).
