Former screener here: peanut butter is approximately the same density as C4 when viewed on TSA’s X-ray screens. It sets off a false alarm on the automated bomb detection software, and the X-ray can’t see through it. You can hide whatever you want inside a peanut butter jar and it will be hidden from the X-ray operator (within certain size limitations).

They didn’t ban it for no reason.

So are Magic: the Gathering cards, apparently. We got stopped because they found solid, rectangular shapes in our suitcases. Explosives? Nope, just our MtG decks.

I can see that. The coating on the cards and the type of paper stock probably make for a nice organic looking orange brick on the X-ray, like a brick of Semtex

Forgive me for saying so but it sounds like this machine isn't very reliable. If it's routinely mistaking cards for bombs and peanut butter for homemade explosives, that feels like a very high false positive rate to me.

Maybe instead of banning everything in sight, it'd be better to fix the machine?

Because it isn't. It's practically all about theatrics to make people feel safer in a post-9/11 society.

False positives are fine though. Mostly no harm done. False negatives are the concern. I realize the TSA is still not that effective but still.

Not being able to bring peanut butter through TSA is hardly going to affect anybody.

Do your children only eat peanut butter with their fingers? Just make it into sandwiches, put it in crackers, dip the celery in it, or whatever it is you do with peanut butter BEFORE you pack it, and it will cruise through the xray

You could always put it in your checked suitcase. It is quite plausible that the number of people who MUST travel with a jar of peanut butter in their carry on is small enough to not warrant an exception.

Hah! That’s hilariously amazing. New one to me. Edit: after some thought… one reason you can’t have water is because there are explosive components that look very similar to water. But they don’t freeze. So if your water is frozen then it can’t be a liquid component of an ied.

You can freeze all matter if you get it cold enough, and stuff that's liquid in room temperature usually doesn't need to be really cold to be frozen solid. Stuff that looks like water when liquid might not look like water ice when solid though.

Can confirm, I used to live with a guy who smuggled drugs all over the country via US mail just by sticking things inside peanut butter jars.

Eventually got caught, but not because of how he shipped things.

Sluggish0351 t1_jdwyyg2 wrote

This doesn't seem like a good excuse considering that there are devices that can sniff out C4, as it has a very distinct scent. There is literally no reason to believe that peanut butter is C4. If they actually cared about safety they would just invest in tools that identified actual threats instead of just making life harder for people traveling.

Have you never shrink wrapped food before? It’s not all that complicated to package smelly materials so that they can’t be smelled. The X-ray is the device that can detect explosives almost perfectly

Lol I used to work with C4. I have used the tech I am talking about. It can sense the scent of C4 on a person's hands that have been washed numerous times. It can detect it through packaging. C4 literally comes in plastic wrapping and is detected through it.

We travelled to Israel with jar of peanut butter in checked luggage. As it happened, the kids liked the food and we didn’t use it.

When at the airport for our return home, Israel security pulled our bag aside, rummaged through and asked us about the peanut butter. They let it go back in the bag.

I understand your point, but you’re grossly overstating it. Hijacking used to be commonplace in the 70s & 80s. Then 9/11 obviously happened and TSA was obviously created in reaction to that, so there are obviously reasons. Whether those reasons justify the existence of TSA is a different discussion tho

tauntingbob t1_jdx3h36 wrote

The number of airplane hijackings was already in decline during the 90s and processes were already improving at airports around the world. Remembering that the TSA is a purely US production and doesn't represent the world, where most incidents happened. The world's airports have improved their processes and it's improved security a fair bit.

But ultimately the evidence is there, the TSA fails almost every test they're checked against by their own organisation. They're probably the least effective security force in the world, other than to frustrate people, they're good at that.

$8bn a year for an organisation who let through banned materials 70% of the time... https://www.forbes.com/sites/ellistalton/2019/01/28/is-the-tsa-really-necessary/

I mean the reason was entirely security theater.

Locking, reinforced cabin doors and air marshals prevent another 9/11, banning toothpaste does not.

There's zero evidence the TSA has stopped a single terror attack, and on top of that they fail their own internal red team tests 95% of the time

“The agency says peanut butter fits its definition of liquid, which it declares as something with no definite shape that takes the shape of its container.”

That could also define a gas.

But my question is why does peanut butter take the shape of the jar? Is it because it is forced to under pressure during the manufacturing process?

If I scoop out a large portion with a tablespoon, does it fill the spoon like a liquid and the excess run out?

If I scoop out a bunch of it and dump it in a measuring cup, does it uniformly fill the cup by seeking a level like water would?

The TSA is a ridiculous bunch of nitwits.

The rule was always about liquids and gels. Or to be more anal,

>Any liquid, aerosol, gel, cream or paste

https://www.tsa.gov/travel/security-screening/liquids-rule

My understanding is that the "liquid" explosives that airlines are afraid of are often quite viscous and more like gels or putties (or peanut butter) than water.

The TSA media person is just doing a terrible job of explaining the rationale. They could just have said that peanut butter is a paste and that's restricted.

antiquemule t1_jduomrd wrote

Not very helpful. Most gels, pastes and other gloop are non-Newtonian and they do not all behave like peanut butter.

To be precise, it is a yield stress fluid, which means that when pushed a little bit, it acts like a solid, whereas when pushed a lot, it flows like a liquid. The (fuzzily defined) amount of push separating the two states is called the yield stress.

Actually they’re completely right. Also, the bigger issue is that you can mix chemicals in there that make it dangerous or can be distilled into powder later.

Not to agree with or defend their assetry, but if I’m remembering correctly gases are fluids. They aren’t liquid though. All (most?) liquids are fluids, not all fluids are liquids. And maybe peanut butter is like pitch. It just takes forever for it to flow. If they would’ve called it a fluid they may be technically right.

Regardless of if it’s actually a “liquid”, it’s properties are those that security would be looking out for in explosives. So doesn’t sound too stupid to me (since we already have restrictions for liquids in general)

I almost always pack peanut butter, PBJ sandwich, or nuts for plane trips. It's a really great, shelf-stable source of protein and fats which makes it a really great travel food when you can't bring a cooler/ice pack.

Obviously I would keep it sealed if someone on the plane was allergic though. I'm not an AH.

Scutshakes t1_jdt0zb4 wrote

There is a YouTube channel called "What's My Line?", it is a channel that archives and uploads episodes of the old panel show of the same name. The famous John Charles Daly hosts this game show where a celebrity panel interrogates the subject on what their profession is, kind of like a game of 20 questions. Sometimes they blindfold themselves to bring in guest celebrities (like Jack Benny and Groucho Marx) and they have to guess who they are talking to.

My memory is a little hazy as this has been some years, but I believe one person had worked as like a mustard taste tester, or worked in a mustard factory, or was an officiant for mustard marriages. I don't remember. But when the panel asked "Is what you [work with] a liquid or a solid?", the subject looked confused. The famous John Charles Daly, in all his grace, wisdom, and good nature, took the subject in for a private deliberation, and very confidently announced that the mustard was a SOLID OBJECT, which of course derailed the entire subsequent line of questioning to an inevitable failure.

For as much as I respect and love the famous John Charles Daly, I will never forgive him for this, and I've never watched another episode since. Peanut butter, a liquid? Maybe. I admit I am not smart enough to argue for or against this. There are better qualified people for it. But MUSTARD? That I have to shake up and squeeze out of a bottle? That I can easily spread over my bologna sandwich in the back of a limousine? I will never agree to call it a solid. Maybe you do, maybe you will side with the famous John Charles Daly purely on the trust he has built with you. But he's not fooling me, and I'm not afraid to look dumb enough to argue against him.
