If my calculations are correct
There are about 631,170,308 babies aged 1-4 on earth right now according to the 2014 census
The average human can survive about 140 degrees farenheit, the temp. of most dishwashers.
A standard dishwasher are about 24 inches, while most babies are about 14 inches in diameter, and 16 can accomodate a dishwasher at a single time
If we stuck all those babies into a dishwasher at the same time on a normal wash, it would take 26,298,762 dishwashers to annihilate every baby on the planet.
