Nosefrida Nasal Aspirator
This disgusting apparatus is absolutely revolting, but apparently it really works. I imagine it would come in handy for parents with tiny babies but seriously: do you really want to be sucking snot out of your kid's face?
Implications - Still, those who have children know the importance of keeping the nasal passages of infants' noses clean. I may not be up for the task, but I'm certainly thankful that such a device exists as there's no safe way parents can get the mucus out of babies' noses otherwise.
