Scientific TheoryBefore the baking soda was added to the water, nothing has changed. Afterwards, you could quickly see a reaction. These two substances form millions of tiny particles. These particles are made of carbon dioxide. Eventually, the popcorn rises to the surface due to the gases being trapped underneath the popcorn. The particles stick to the popcorn and makes it rise or descend. When it rises to the surface of the water, the carbon dioxide pops and goes down. This is because the vinegar and the sodium bicarbonate. When it reaches the bottom, the particles will again stick to the popcorn.
