In any chemical reaction there are two parts. Reactants are the substances that go into the reaction; products are the new substances that are produced.
If we tie a paper clip to a string and add borax with hot water and food coloring then the crystals would grow on the paper clip because of the chemical reaction happening with the paper clip and the borax.
Analysis We placed the paper clip towards the bottom, because of this the crystals grew on the bottom of the cup. This reaction is called an ionic bomb. The paper clip created a reaction with the borax.
