Acid drops were an incredibly sour boiled sweet. They were round and lemon in colour, in a yellow cellophane wrapper. You could buy them in quarter bags. We used to have competitions to see who could eat the most Acid Drops in one go as they were so sour that they would turn your face inside out (well, that's what it felt like!).
