Biological warfare! Bubbles containing trapped bacteria act as tiny 'microbial grenades'

Daily Mail - Science & tech 

Bubbles containing trapped bacteria can act as tiny'microbial grenades', new research shows. Scientists found these tiny natural explosives had the power to launch microorganisms into the air at speeds of more than 30 feet (10m) a second. A single droplet is thought to carry up to thousands of microorganisms, and each bubble can emit hundreds of droplets. A bubble covered in bacteria floating on the water's surface also lasts ten times longer than an uncontaminated one, scientists also found. During this time the cap of the contaminated bubble gets thinner, according to researchers at Massachusetts Institute of Technology (MIT).
