Whistle Pops

Whistle pops are a type of candy that look like small pellets or balls. When you put them in your mouth and suck on them, they make a fun popping sound and taste sweet or fruity.

But how do they work? Well, inside each little candy pellet, there is a tiny pocket of pressurized air. When you suck on the candy, the pressure changes and the pocket of air is released, causing the popping sound.

It's kind of like when you blow up a balloon and then let the air out quickly to make a loud noise. Except in this case, the candy is doing all the work for you!

Some whistle pops even have a special shape or design that makes them whistle or sing. These candies are a fun treat to enjoy and play with, but remember to always chew and swallow them carefully to avoid choking hazards.
