Did You Know? You Can Bring Water Through TSA—but You'll Need the Right Bottle
Staying properly hydrated in the summer can already be difficult, but the Transportation Security Administration (TSA)'s strict rules surrounding liquids can make it even harder to keep your thirst quenched while traveling. Bottled water at the airport can cost a pretty penny, and since all carry-on liquids must adhere to the 3-1-1 rule—that is, every one person only gets one bag containing liquids, and those liquids must be in bottles of 3.4 ounces or less—sneaking in a fresh bottle of Evian is clearly out of the question.
However, we've recently discovered a genius way to get around this rule and get water through airport security: And it's so simple, you might be angry you didn't think of it sooner. You can sneak H2O through security by just freezing it. That's right—you can bring in a full bottle of water through TSA, so long as it's frozen solid. 'Frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening,' a U.S. TSA spokesperson previously shared with CNN.
Keep scrolling for eight reusable water bottles you can safely use to get frozen water through TSA, plus our tips on how to get frozen water through TSA hassle-free. Ahead, you'll find squishy, foldable silicone bottles, durable, brand-name plastic bottles, and even water bottles that perform double-duty as facial misters—all starting at $13 at Amazon.
You should only freeze water in food-grade, BPA-free plastic or silicone reusable water bottles, and you should aim to fill them only two-thirds of the way full with water before freezing, to prevent the bottle from breaking.
This is because when water freezes, it expands. If you fill your water bottle to the top, it will have no room to expand and may crack or damage even the most durable, flexible plastic water bottles.
We hate to be the bearer of bad news, but we strongly don't recommend freezing your beloved Stanley insulated bottle (sorry!). Metal, insulated, and glass water bottles can become deformed or even shatter due to the frozen water expanding inside, regardless of how full it is, which is why many popular brands like Owala and Camelbak warn against freezing their insulated, glass, or steel bottles.
Unfortunately, if your water thaws before you make it through TSA, you'll likely be asked to dump it out. For this security checkpoint hack to work, the water in your water bottle must be fully frozen into a solid state.
'If frozen liquid items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 liquids requirements,' that aforementioned TSA spokesperson shared with CNN. Considering most water bottles far exceed the 3.4-ounce liquid cutoff, you'll probably have to say 'sayonara' to your not-so-frozen carry-on water.
Now that you know how to master this packing hack, it's time to find the perfect water bottle for your next trip. Keep scrolling to explore the top-rated options at Amazon that will make great travel companions this summer.

TSA Calls Out Traveler for Attempting to Bring Fuel-Filled Camp Stove Through Security: ‘Let This Be a Learning Moment'
A plane passenger tried going through security at Pensacola International Airport in Florida with a fuel-filled camp stove in their carry-on bag TSA poked fun at the situation in a Facebook message this week, reminding all travelers that stoves with attached propane tanks are not allowed through security "Camp stoves are allowed in carry-on or checked bags only if they are empty of all fuel and cleaned so that no fuel vapors or residue remain," according to TSA guidelinesTSA has issued a PSA after a passenger tried finessing a fuel-filled camp stove past security. The Transportation Security Administration poked fun at the incident in a post shared to its official Facebook page on Wednesday, June 11. The friendly reminder detailed the passenger's attempt at bringing the cooking device in their carry-on bag while traveling through Pensacola International Airport (PNS). 'Listen, friends, we love watching cooking shows as much as you do, but any top chef has to know that you cannot bring a stove with a propane tank attached through airport security in your carry-on bag,' TSA wrote in the social media post. The agency gave a shoutout to the team working at PNS for finding the stove as it made its way through standard checkpoint security on Monday, June 9. 'This one was hard to miss, but great job by our team at Pensacola International Airport (PNS) for discovering this during standard checkpoint screening on Monday, and educating the passenger on the regulations we have around prohibited items" TSA wrote in the post. 'The passenger said he was unaware that stoves and propane tanks couldn't be carried on a plane, so let this be a learning moment for everyone… propane tanks cannot and do not belong in either your carry-on or checked bags,' the post continued. Included in the post was a photo of the red camping stove discovered by the TSA team. Camp stoves are allowed on flights, but only if they are packed according to TSA's guidelines, which prohibit any fuel being brought along. 'Camp stoves are allowed in carry-on or checked bags only if they are empty of all fuel and cleaned so that no fuel vapors or residue remain. Please wrap cords and layer items in bags so officers can get a clear view of the items,' a statement on TSA's website reads.

Cooking 'Business Class' dining,' wrote one Facebook user. 'The food I prepare on that mini stove tastes so much better than airline food,' wrote another user. Read the original article on People

TSA scolds passenger for attempting to bring bizarre item on board plane: ‘Learning moment'
Ahead of Father's Day weekend, the Transportation Security Administration (TSA) has taken to social media to issue light-hearted warnings and guidance about all manner of airplane-averse goods — improperly packed jerky, meat marinades in excess of 3.4 oz, and pocketknives, among other items. However, when a passenger tried to bring a camping stove — complete with fuel — through a security screening in Pensacola International Airport, the agency got serious in a Facebook post. 'This one was hard to miss, but great job by our team at Pensacola International Airport (PNS) for discovering this during standard checkpoint screening on Monday, and educating the passenger on the regulations we have around prohibited items,' TSA wrote in response to the incident. According to the agency, the passenger 'said he was unaware that stoves and propane tanks couldn't be carried on a plane.' Who would have guessed that combustible fuels and airplanes don't mix? These skeptical commenters. 'He knew! If you have to bring travel-size shampoo, you know. Good catch by TSA,' applauded one user, while another agreed: 'A propane tank?!? Someone is sorely lacking in common sense!' 'This is truly a weird carry-on,' said one bothered reader. Luckily, determined campers are allowed to bring clean stoves, provided they're completely empty of fuel, the agency clarified. Several know-it-all passengers tried to come to this Florida man's defence. 'Those use Butane. FYI. But thanks for keeping me safe from small appliances,' said one sarcastic camping expert. However, many viewers simply didn't care about this distinction. 'Love the comments that it's butane, not propane. Who cares? It is flammable and shouldn't be on a plane. Rampant stupidity,' one staunch reply read. 'One brain cell,' another decreed. This incident is the latest in a string of several other recent strange airport security happenings — with one high-profile example being Ellen Pompeo's fancy sunflower seeds. Many passengers opt to bring their own snacks to the airport to save time and avoid the exorbitant costs of limited terminal restaurants, but for the convenience of both the agency and travelers, TSA provides airport-goers with a comprehensive list of food items that are travel-friendly. While the overall consensus on the wild camping item the Florida passenger brought was harsh, this commenter saw the humor in the situation and cut the offending traveler some slack: 'Oh, come on, TSA, be considerate. The food I prepare on that mini stove tastes so much better than airline food.'

Caitlyn Jenner Sends Urgent 12-Word Message From Israel
Prominent U.S. figures like Caitlyn Jenner and Scott Jennings are in Israel amid the country's strikes against Iran, and Jenner had an urgent 12-word message for daughter Kylie Jenner. It won't be easy for either Jenner or Jennings, who are on separate trips, to leave, as the Ben-Gurion airport in Tel Aviv has now closed due to the unrest. "I spoke with my daughter Kylie, and she urged me to stay safe. I reassured her," Caitlyn Jenner said on Israeli television, according to Daily Mail. Jenner told Kylie: "Don't worry, I'll keep myself safe, and they'll take care of me." Jenner has posted photos on X showing scenes from Israel. "My heart is here, with the beautiful people, in @Israel." Jenner posted on X on June 12. The State of Israel's official site also posted photos of Jenner in Israel on X, writing, "@Caitlyn_Jenner at the Western Wall in our capital Jerusalem." Jenner, who was in Israel to appear at a pride parade, also gave interviews to Israeli television. Jennings, the CNN commentator, was also in Israel when the attacks ensued. "Definitely not getting out today. Lol," Jennings told the Daily Mail on June 13 "from his hotel in Tiberius, on the shore of the Sea of Galilee." Daily Mail described Jennings and Jenner as being "stuck" inside Israel. It's true they wouldn't be able to fly out of the country if they wanted to. "Notice to the General Public. Due to the current special security situation, all flights to and from Ben Gurion Airport (LLBG) are canceled until further notice. Please be advised: Do not travel to the airport," the Tel Aviv airport in Israel wrote on its website on June 12 and 13. Jennings posted a video of what he presumes were Iran "missile attacks" in response to Israel's attacks on Iran. "Just recorded this over my hotel on Sea of Galilee in Israel - and then a minute later heard a BOOM. this is looking south. Hearing booms in distance. Iran missile attacks I presume," he wrote on X on June 13. Jennings voiced support for Israel on X, writing, "We are in a fight for Western civilization around the world. As I type this from Israel, it's abundantly clear they are in a fight for their very survival as a nation."Caitlyn Jenner Sends Urgent 12-Word Message From Israel first appeared on Men's Journal on Jun 13, 2025
