Here’s the deal: the UK’s Civil Aviation Authority forbids Christmas crackers in the cabin carry-on. The TSA in the US isn’t a huge fan either, though they leave it to the individual officer’s mood.
Why the fuss? Because that little “cracker snap” contains about one gram of impact-sensitive explosive. It’s the same stuff used in party poppers and toy caps—so tiny you’d need a thousand to make a firecracker.
But airports don’t care about scale. They see “explosive” in their manual and picture a gummy bear that might blow up a bag of peanuts. Ridiculous? Maybe. But rules are rules.
What Actually Happens at Security
If you toss a pack of crackers into your carry-on, expect the bag to get pulled. A nice officer will open it, inspect the cardboard, and probably say, “You can’t take these onboard.”
You then have two choices: hand them over to the nice officer’s trash bin, or run back to check them in your hold luggage. And yes, that means missing your boarding call for a few paper crowns and a plastic whistle.

But here’s the fun twist: checked baggage is usually fine. The cargo hold isn’t pressurized the same way, and the tiny snaps aren’t a big deal down there. So if you’re checking a bag, stuff them in there—just not too close to anything flammable, like a bottle of prosecco.
