Photographs from the “Ink in water” series by Leonardo Aguiar
Although images of ink dissolving into water might be cliche, its responsive motion and its gradual changes of density create attractive morph of form and translucency. The Brownian Motion is a part of particle theory which describes this disperse of particles toward random directions in water and air.
The Brownian motion is caused by random collisions of molecules by their motions due to heat. Temperature, sizes and mass of molecules are factors that affect the intensity of the Brownian Motion. Higher temperature would increase speed of molecules which creates more active Brownian motion model. The lower temperature would do the opposite. Bigger molecule sizes would increase chances of collisions but tend to create less active Brownian motion model because of its greater masses. On the other hand smaller molecules might not collide as much but increase their reactions due to their smaller masses.

Thanks Leonardo Aguiar for your contributions!!

I didn’t know that heat would affect the intensity of the Brownian Motion. Maybe next time I photograph ink in water I will heat up or cool down my pigments.
Thanks for sharing!
