What does the inside of a ping pong ball smell like?

Answer 1

The smell of the inside of a ping pong ball is most similar to Vick's Vaporub. During the production process, chemicals are used in production that cause the interior lining to develop a strong chemical smell. It can be a fun party trick to show your friends. For instance, in the middle of beer pong, you can break open the ball everyone was using and say, "hey guys, smell this!"

Answer 2

Table Tennis balls are made of a type of plastic called celluloid. The odor in the ball is a by-product once the ball becomes cracked and the inside is exposed to air.
