Bug-a-Salt: Insect Gun "This Fly Killing Gun Uses Salt as Ammo, It’s Ingenious and Awesome!"
A designer called Lorenzo Maggiore has developed a pump-action "insect eradication" device called Bug-a-Salt that fires salt at unsuspecting creepy-crawlies.
The device has a range of between 0.9 and 1.5 metres and has a holding chamber for enough granulated table salt for 50 shots. In order to shoot, the user must first of all pump the handgrip. This triggers a pop-up sight and an automatic safety catch, which has to be manually removed before shooting. Then it's a question of taking aim at a fly or slug and pulling the trigger.
