what is the difference between chewing gum and bubble gum?
Rating Newest Oldest. Best Answer: The difference between bubble gum and chewing gum is the gum base. Chewing gum base is a natural gum called chicle harvested from the sap of a tropical tree called a sopapilla tree. This kind of gum is chewy but it will not blow a large bubble. Bubble gum base, on the other hand, is a mixture of starches and polymers made in a laboratory and specially formulated to blow bubbles.
