#18: Banned in Schools (1970s) / Discontinued in 2004
In the 1970s, some schools banned Astro Pops because kids discovered they could harden into sharp points and be used as makeshift weapons. Despite this, the candy held on for decades before being discontinued in 2004 due to declining sales and shifting tastes.

Fans remember Astro Pops as both candy and toy, edible experiment and novelty. Though they briefly resurfaced under new ownership, nothing matched the original’s space-age magic. Today, they remain a symbol of an era when candy wasn’t just about flavor — it was about imagination.
