Some people just can’t help themselves. No matter how many signs, announcements, or rules exist, there’s always someone who thinks they can outsmart airport security. TSA has seen it all—items stuffed in shoes, wrapped in tinfoil, or hidden in the weirdest places imaginable. Spoiler: It never works.
Most of the time, it’s not even about sneaking something serious. People forget the basics, assume rules don’t apply to them, or just hope no one will notice. But TSA notices. And when they do, it means delays, extra screenings, and sometimes even a missed flight. Not exactly the great start to a trip.
The truth is, security isn’t out to make travel miserable. But if you show up with things you shouldn’t have, they’ll absolutely slow you down. Some mistakes are understandable, while others are just plain ridiculous. Either way, it's easier to just follow the rules. Because the last thing you want is to be the person holding up the line while agents pull some "creative" packing choices out of your bag.
Snow Globes
It may seem harmless, but snow globes contain liquid, which makes them subject to TSA's restrictions. If the liquid inside exceeds 3.4 ounces (100 milliliters), it won’t be allowed in your carry-on. Even smaller ones must fit within your quart-sized liquid bag. Many travelers try to bring back snow globes as souvenirs, only to have them confiscated at security. If you really want to bring one home, pack it in your checked luggage or look for a TSA-approved size. Otherwise, you might have to say goodbye to that festive little keepsake at the checkpoint.
Bowling Pins
Bowling pins may not seem like a threat, but TSA considers them potential bludgeoning weapons. Because of their size, weight, and solid construction, they aren’t allowed in carry-on luggage. Many travelers don’t realize this and attempt to bring them through security, only to be stopped. If you’re traveling with bowling gear, check the pins along with your bowling ball to avoid any issues. Otherwise, you might have to leave it behind or pay an unexpected checked baggage fee at the last minute.
Magic 8 Balls
This classic fortune-telling toy contains liquid inside, which automatically makes it a no-go for carry-on luggage. The liquid volume exceeds the 3.4-ounce limit, and since it isn’t in a transparent container, it can't go into your liquids bag. Travelers often think TSA agents won’t notice or won’t care, but the moment it goes through the X-ray machine, it’s an instant red flag. If you want to bring one home, pack it in checked baggage. Otherwise, you’ll have to leave your future-seeking friend behind at security.
Canned Foods
TSA technically allows canned foods, but they often cause problems at security. Cans are opaque, making it difficult for X-ray machines to determine their contents. Some also contain liquids exceeding TSA’s limit, leading to confiscation. Items like soups, sauces, or even canned fruit may be considered too risky. Even solid foods in cans can be flagged for additional screening. If you must bring canned goods, pack them in your checked luggage. Otherwise, be prepared for security delays and possibly having to toss that special tin of imported delicacies.
Cast-Iron Cookware
Cast-iron skillets are heavy, solid, and could easily be used as a weapon, which is why TSA won’t let you carry them onto a plane. Some travelers think that just because it's cookware, it should be allowed, but these pans raise red flags every time. Cast iron is also dense, making it difficult for X-ray scanners to see through, which often leads to additional screening. If you’re traveling with a beloved skillet, check it in your luggage. Otherwise, you’ll have to part ways with it at security.
Golf Clubs

Many travelers assume sports equipment is fine for carry-on, but golf clubs are explicitly prohibited. TSA considers them potential weapons, and they’re too large to fit in overhead bins. Some travelers try to get away with carrying just a single club, thinking it won’t be an issue, but even that won’t make it past security. If you’re planning a golf trip, use a proper travel case and check your clubs. Otherwise, be prepared to rent equipment at your destination or leave your lucky putter behind.
Camping Stoves
Camping stoves themselves aren’t banned, but if they’ve been used with fuel, they become a problem. Even if completely empty, any trace of residual fuel is considered hazardous, which means TSA will likely confiscate it. Some travelers try cleaning them thoroughly, but unless you can prove there’s no fuel residue, they might not get through. If you must bring one, ensure it’s brand new or completely disassembled and dry. Otherwise, it’s best to check it or rent one at your destination.
Cremated Remains
Bringing a loved one’s ashes through security is allowed, but it often leads to heart-wrenching issues. TSA permits cremated remains in carry-ons, but they must be in a container that can be scanned. If the urn is made of metal or another opaque material, security agents won’t be able to confirm its contents, and they legally cannot open it. Many travelers arrive with urns that are non-scannable, resulting in missed flights or, worse, having to leave the remains behind. Always use a TSA-compliant container and check airline policies before traveling with ashes.
Foam Toy Swords or Guns
Even if they’re made of foam or plastic, toy weapons often cause trouble at security. TSA has strict rules about anything resembling a weapon, and officers err on the side of caution. A foam sword or realistic-looking toy gun could be mistaken for a real weapon at a glance, leading to delays or confiscation. While some smaller, obviously fake toys might be allowed, it’s up to TSA’s discretion. If you’re unsure, pack them in your checked luggage to avoid unnecessary hassles at security.
Jars of Peanut Butter
Peanut butter may seem like a solid food, but according to TSA, it’s classified as a liquid or gel. Since you can’t bring more than 3.4 ounces, any full-sized jar will be confiscated. Many travelers don’t realize this until security pulls them aside, leading to an inconvenient repack or a surrendered snack. If you really need to travel with peanut butter, pack it in checked luggage or portion out a small amount in a TSA-approved container. Otherwise, you’ll have to part ways with your peanut butter at the checkpoint.
Surge Protectors with Extension Cords
While regular power strips are typically allowed, surge protectors and extension cords often get flagged for additional screening. These devices can interfere with security scans, and some international airports don’t permit them at all. Travelers who pack bulky surge protectors in their carry-ons may face delays while TSA inspects their bags. If you need one for your trip, consider packing it in your checked bag or opting for a smaller, travel-friendly version that won’t cause unnecessary scrutiny.
