Technically Correct

The TSA is something that shouldn't exist in its current form. They very often fail their audit checks and normalize invading your privacy to an extreme degree like body scanners and pat downs. If water bottles are considered potentially explosive then why dump them on a bin next to a line of people where they can go off? This is low grade security theater that inconveniences passengers at best.

It is allowed.

It's actually stated on the TSA website that frozen liquids are permitted. https://www.tsa.gov/travel/security-screening/whatcanibring/items/ice

The longer they discuss the less it is allowed.

Do you think they get mad if I bring plasma

I've actually done this successfully. TSA agent knocked on it, and said no problem.

If i somehow would be stopped, I'd love to argue what is liquid or not, and what could be liquid if it's just hot enough.

you could freeze H2O2 and blow up something later.

Recently, I'm flying quite a lot, so I must try it, just to see if it works.

I brought frozen fish with ice packs through TSA. The TSA guy was a fisherman and wanted to talk about fishing.

TSA vs Karen, quite a match

Btw, why not water?

So how about a bottle of dry ice?

Dear TSA,

The human body is mostly water. And it's way more than 3 oz.

Came across this video where they were able to take ice through TSA. Your mileage may vary, follow at your own risk.

A friend has been challenged when trying to bring a nordic cheese (from Norway to France). The TSA equivalent said that it could be liquid if hot enough. Yeah... glasses too.

Or just bring an empty bottle through and fill it up at the tap/water fountain?

Lemme Google the freezing temp of whatever explodey juice they think we all have.

Does sunscreen freeze solid at regular freezer temperatures?

It's worked for me

The best kind of correct

What's more, it's technically just a mineral.

I believe the rule limits the actual container size if it contains liquid. Even if you have a nearly empty water bottle or are nursing the last dregs of a full size tube of toothpaste, it gets dumped or thrown out. So technically, if any water has melted at all, it counts.
