A company called Ideal Conceal has invented a .380-caliber pistol that can fold up to look like a cellphone. The inventor, Kirk Kjellberg, says he got the idea when a child noticed his concealed weapon in a restaurant. The child yelled out "Mommy, Mommy, that guy's got a gun," which brought on unwanted attention. The website claims it "will be virtually undetectable because it hides in plain sight," and will be available this year.
