In 2003, Florian Jenett and Valentin Beinroth created guns from tinted ice, making them look real at first sight. They placed about 50 handgun replicas in downtown Frankfurt. In 2009 they did a new edition of their Freeze! project but made the guns edible by using coke, licorice, cherry and food coloring. So, go eat a gun.
