You should make a density trap, you get different liquids with different density's ( corn starch , water , alcohol , syrup) and pour them into a big vase and the different density's will sit on top of each other . the best thing to do is to use food coloring so that  each level is a different color.

The correct answer is A. Charging by friction

Explanation

When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction
