This picture was taken when a negatively charged comb is placed near a stream of water, the stream of water bends without the comb actually touching it. When we charge the comb, it acquires extra electrons and becomes negatively charged. Since water doesn’t have an electrical charge, and is polar meaning it has more electrons on one side than the other. The comb helps produce a charge in the water. When the negatively charged comb is placed near the water, it causes the water molecules to rearrange. The electrons in the water are repelled while the protons are attracted to the comb. This causes the stream of water to bend. It is also called “Polarization”.
