@@HeidiHisrich I would suspect that through diffusion, the diameters might get slightly larger as the paper absorbs the droplets. I used my HoverCam Solo 8, took photos with a mm. ruler for each height and uploaded this for students to gather their data. Thanks for your help.
you’ve saved a random 8th grade kid years later, thank you ❤️
