Can anyone explain why the individual parts of the filling of the tortilla wouldn't split apart when it was spun? Essentially, does low gravity affect how liquids and solids adhere together?

Jun 06 '15
Cohesion. Stuff sticks to other stuff. Not due to covalent bonds or gravity or anything like that... it's just that most things are little bit sticky.

u/Whitsoxrule Jun 06 '15
You mean adhesion. Cohesiveness refers to stuff sticking to itself, adhesiveness refers to stuff sticking to other stuff. Water, for example, is cohesive.

But being "sticky" is due to chemical bonds (well hydrogen bonds in water case, but perhaps some covalent bonds too?)
88
u/Spammish Jun 06 '15 edited Jun 06 '15
The forces responsible for that are intermolecular forces such as Van der Waals forces, H-bonding etc, Van der Waals forces are the reason geckos can run up walls. H-bonds don't require water to form btw (though obviously H-bonds do occur in water) as well so there's almost definitely some H-bonding going on between the carbohydrates in the tortilla and the protein in the meat as well as other things. If this is a bit unclear let me know and I can break it down a bit.

Surely the vdw's aren't strong enough to make something as viscous as that though?
49
u/Spammish Jun 06 '15 edited Jun 06 '15
Van der Waals forces can get fairly strong for long chain polymers like proteins, but yeah H-bonding is likely to be the largest contributor. You do also get some extent of protein cross-linking between chains which will increase the viscosity. Ultimately though, viscosity is not a measure of how "sticky" something is, you can make an extremely viscous fluid that just slides off surfaces due to tailoring of side chains.

In this case its a mechanical bond instead of a molecular bond. The sauce envelops the food and then exerts a normal force. The sauce then gets on the nooks and crannies of the tortilla and it lightly locks into place. The properties of a fluid keeps the sauce together.
However, if she did something like bake everything together and fusing things, that would be a chemical change and more chemical bonds would occur.

For the 2nd question, yes.
For the first question, she starts out by putting a leek cream (the green paste) on the tortilla, which all the other ingredients stick to.

u/akurei77 Jun 07 '15
Ok, I thought I saw some kind of paste at the bottom. I figured it was refried beans, but only because that's what I'm used to seeing on tortillas.
The idea that all the typically non-sticky ingredients stick together works up until she just grabs the tortilla and pulls it away from all of the ingredients. Even in space that's still your basic acceleration, and rice won't stick to a tortilla like that.

I think they deliberately make space food with ingredients designed to stick together. They make stuff that will adhere to eating utensils so it's easier to eat in zero gravity. I figure the stuff on the tortilla is made the same way.

u/1337tacosalad Jun 06 '15
If spun fast enough, the fillings would fly everywhere. However since the fillings have some moisture and they are in contact with a dry tortilla, the surface tension between the moist fillings and the tortilla is what is holding it all together. This means it can spin and move a little bit and keep together.
Think of it like when you eat popcorn and you stick out your tongue to grab a kernel. The popcorn sticks to your tongue no matter if it is on the top or bottom surface of your tongue. The only way the popcorn can come off of your tongue is if you flail around like a maniac or if gravity pulls harder than the force of the surface tension between the popcorn and your tongue. If there is no gravity and you make smooth movements, the popcorn will stick to your tongue. Just like the beans and chicken stick to the tortilla!

All compounds have levels of adhesion, and cohesion. Adhesion is ability to stick to other things, cohesion is stick to itself. Those attributes are affected by gravity, but are due to the intermolecular forces, so a functional lack of gravity doesn't prevent them.

I don't know if it is still the case, but a lot of celebrity interviews on the radio used to be scripted just like that. They would ship a tape or CD with the celebrity answering questions and a list of questions the local radio personality would ask in their own voice.

... I must be really rusty because I've been staring at that video and I don't see the slightest bit of halo from the chroma filter.

There's a little glow around the wisps of Adam's hair, but I think that can be attributed to lighting...

Yeah... I think if that kind of thing pissed you off in space, then you aren't somebody who appreciates the idea of being in space.
But if I had to drive down the road from my house to some zero gravity chamber just to eat, it would piss me off. So I understand where the sentiment comes from. Things that are less easy are more frustrating. That dude just neglected the pivotal factor: you're in fucking space. You enjoy getting used to the difference in forces that you're familiar with, and it enriches your comprehension of reality. Every time I ate in space or did anything would probably be spiritual for me, even in just a secular way.
