However, this far-fetched sounding piece of ammunition isn't designed to kill, the Daily Mail reported.
Dubbed 'Nonlethal Warhead for Miniature Organic Precision Munitions', there isn't even a prototype yet - but it's on the U.S Army's wish list.
It's been demanded through the U.S Government's 'Small Business Innovation Research' program, which persuades companies to research and build products in return for a potential commercial deal.
For the floating bullet, the Army confessed that 'this effort will require innovative research and advancements in non-lethal technologies which can be packaged within a very small volume and weight' and suggests that designers should consider 'mechanical, such as rubber balls; acoustic; chemical; electrical; or dazzle'.
The idea certainly isn't pie in the sky, as the U.S Army already has a 'kamikaze' robotic drone called Switchblade, which quietly hovers before dive-bombing and blowing up a target.Credit:santabanta.com
