Atoms are actually very small...you could line up around 10000 of them across the width of a hair!!!!! atoms are made up of neutrons, electrons and protons. We also talked in our class about their charges: electrons are negatively charged, neutrons have no charge whatsoever and protons are positively charged.
We set up this experiment in class to have fun playing with charges: we rubbed an acrylic rod with a silk cloth and we got positive charges, which instead attracted the negative charges of the cork balls.
As a result, the cork balls started to rise "effortlessly" when Lorena brought the rod closer to the balls.
I want to thank Sara for explaining the experiment, and also María for helping with the "charging process"
This is Science and it ALWAYS works.
Give it a try if you like!
