Whistle Pops

Whistle Pops (called Melody Pops in some countries) were a lollipop brand produced by Spangler Candy Company[2] starting in the 1970s that were designed to make a whistling sound.

[3] They were produced with a hole in them, and when blown into, a whistling sound would emanate from the confectionery.

[3] After their being discontinued for a few years, candy company Chupa Chups reintroduced Whistle Pops, renaming them Melody Pops, and began marketing them in the United States.

[3] Melody Pops are marketed with a tagline stating "play real music".

In the United Kingdom (UK) some pharmacies stock Whistle Pops.
