Warheads came out when I was in fifth grade. They were so so sour they were dangerous. My mother said they were self-destructive. She really worried that it would start with Warheads and end in my watery grave, a snippet of a broken bungee cord at my ankle.
Lemonheads never got old.
Sour patch kids, and their many grocery-store bin imitators, were the classic element. Always will be.
