Chrissy Teigen tested TSA guidelines by live tweeting her attempt to bring cold gravy onto a plane

• Chrissy Teigen tried to take cold gravy onto a plane, and asked Twitter whether it would be allowed.
• The TSA guidelines are a bit confusing when it comes to food, and the gravy was so thick it didn't move when the container was held upside down.
• Teigen found that cold gravy is allowed if she mixed it with her mashed potatoes.
• "The general rule of thumb is that if you can spill it, spread it, spray it, pump it or pour it, then it should go into a checked bag," A TSA spokesperson told USA Today.

When it comes to taking anything remotely liquid through a TSA checkpoint, it's best to just leave it at home when you're in doubt. But Chrissy Teigen couldn't help herself.

The TV host, model, cookbook author, and frequent flier thought her homecooked gravy was simply too good to leave behind. She posted a video on Twitter to play a unique game of "Will It Fly?" with her fans on a recent trip.

The gravy was very cold by the time she and her entourage got to the airport, so it was thickened to the point where her assistant could hold the container almost completely upside down without it spilling. Is it a liquid at this point? That's really up for the TSA to the decide.

While liquids, creams, and gels are prohibited by the TSA in containers larger than 3.4 ounces, the rules can get fuzzy when it comes to food. It's pretty much a given that water and other drinks have to be thrown out, though sometimes you can find a loophole by freezing your liquidy foods before going through security.

Some people on Twitter responded to her tweet that she should have frozen her beloved gravy, and some suggested putting it in a diaper, which is ... creative, if disgusting.

Put to the TSA test, the gravy passed inspection. Not because Teigen is a celebrity, but because she used a very clever TSA hack: mixing it with mashed potatoes.

Of course, it's possible that Teigen got lucky with a very understanding TSA agent. Jenny Burke, a TSA spokeswoman, told USA Today, "The general rule of thumb is that if you can spill it, spread it, spray it, pump it or pour it, then it should go into a checked bag."

The TSA also has special rules for certain types of food, including gravy which should be checked if it is in quantities above 3.4 ounces. But, who only wants 3.4 ounces of gravy? There are no specific guidelines for mashed potatoes, however, other foods of similar consistencies generally are allowed in checked bags unless they're under 3.4 ounces as well.

Ultimately, it's up to the TSA agent whether something is allowed through.

And if you're wondering whether all this fuss is really worth it for a little gravy, you clearly haven't had much gravy in your life. According to Teigen, the sauce was a copycat recipe of Popeye's famous cajun gravy.

But we can go ahead and add this to the list of the weirdest things that are apparently okay to bring on a plane with you.

Honestly, we'd be tempted to eat those mashed potatoes as soon as we got on the plane, even if they are ice cold.
