is blowing bubbles a physical or chemical change

In a nutshell, a chemical change produces a new substance, while a physical change does not. This results in the rearranging of atoms in substances to form the products of a chemical reaction, which are brand new molecules that cannot be easily reverted back to their original state.Sometimes it is difficult to tell if a chemical reaction has taken place.
