Hi,
I am trying to determine the size of a molecule..by doing the oil drop experiment where we drop a tiny droplet of oil on water covered with a thin layer of powder...and then make calculations based on the diameter of the circle... the droplet forms in oil.
However, the oil droplet for me is not making a circle..rather is spreading out irregularly. How can I fix this.
Everything i have used is according to this site:
but i have used talcum powder instead of lycopodeum powder
