Teardrops might not seem too interesting, but within theselittle beads of saltiness and sadnesstheres some pretty interesting stuff going on.
The project started with some good old scientific curiosity. On a Medium blog post, Mikkers explained science says that every tear has a different viscosity and composition. All tears contain a variety of biological substances including oils, antibodies and enzymes suspended in salt water. But how does this relate to the ‘real world.’
“This tear is harvested after cutting white onions.”Maurice Mikkers.
There arethree different types of tears: emotional tears, associated with feelings of sadness or joy; reflex tears, which result from irritation of the eye; and basal tears, the ever-present moisturiser that helps keepthe eye wet and healthy.
Mikkers wanted to see for himself whether each of these had observable differences when placed under a microscope. He spent an evening experimenting with some friends, whereby hecaused them to shed tears either by cutting onions, eating a hot chili, through sadness or tears of joy. After collecting the drops with amicropipette,he placed themonto a microscope slide and left them to crystallize for a few minutes.
Although there wereno clearly discernible patterns between the different types of tears, Mikkers managed to capture the intricate and varying structures of thetears’ salt crystals. As he concluded, So I think its safe tosay that the differences in tears that are seen are not showing differences between the origins of crying…Nevertheless they are beautiful to look at.
