Popping candy earns its search traffic honestly — it's one of the few sweets that does something genuinely surprising in your mouth, and plenty of people search for it just to understand how the crackling actually happens rather than to relive a specific childhood memory.
The chemistry behind the crackle
Popping candy is made by mixing molten sugar candy with pressurised carbon dioxide gas before it sets. As the mixture cools and hardens, tiny gas bubbles get trapped inside the candy under pressure. When the candy hits saliva in your mouth and starts dissolving, those trapped bubbles are released all at once, producing the crackling "pop" sensation — it's a genuine physical reaction, not a flavouring trick.
Older than you'd think, and a famous urban myth
The base process was developed by food chemist William A. Mitchell at General Foods in 1956, but it wasn't commercialised until Pop Rocks launched in the US in the 1970s. A persistent urban legend claimed that mixing Pop Rocks with fizzy drinks like cola caused a child actor's stomach to explode — this is a well-documented myth with no basis in fact; combining the two just produces extra fizzing, nothing dangerous.
What we actually stock right now
We don't currently stock popping candy directly — it isn't in our range at the moment.

FAQ
How does popping candy actually pop?
Carbon dioxide gas gets trapped inside the candy while it's being made under pressure. When the candy dissolves in your mouth, the trapped gas escapes all at once, creating the crackling sensation.
Is it true that Pop Rocks and cola are dangerous together?
No, that's an urban legend with no factual basis. Mixing the two just causes extra fizzing from the released gas — there's no real danger.
Do you sell popping candy?
Not currently — it isn't in our range. We do stock several sherbet and fizzy sweets that give a similar tingling sensation, including Swizzels Double Dip, Triple Dip Sour and Haribo Rainbow Pixel Fizz.
When was popping candy invented?
The underlying process was developed in 1956, though it wasn't sold commercially as a sweet until Pop Rocks launched in the 1970s.
