For sure!

Being a science graduate myself, I’m familiar with the physics of such a size difference. What I like about writing, especially in a universe with a supernatural bent, is that we can take a lot of those rules and bend them.

Sam’s size alone would be difficult to maintain for such a long lifespan. They should have higher metabolisms, age quicker, eat a lot more for the energy needed for this. Falling would do less damage, it’s like when you drop an elephant, it splats, when you drop a mouse, it bounces. (ffs who comes up with these experiment ideas; protect the elephants)

Especially in the extra tiny Jacob AU we do step back from those rules. He won’t have to worry about the water sticking to him that much. Sam can hurt his wrist when he falls just like Dean can, and they can (mostly) communicate normally.

(Jacob has some issues talking to Dean in the horror story, as we’ll soon see. He is too smol even with our lenient rules.)

We did have a previous ask come in about this like a year ago, so if you want to read some more into our thoughts, check it out here!

Sam is not at a scale where this would be a problem. He might be much smaller than a regular human, but like a mouse, he’s a small mammal that would drink the water. Mice are smaller than Sam and are able to drink water without an issue, as we can see by their survival for millennia. 

The surface tension of the water (what makes it ‘sticky’), is not too strong for them to drink. The same goes for Sam’s people. The smallest living mammal is barely 2.5 inches long at its longest, and these shrews do not choke on water when they drink. If we go smaller than an inch for scale, perhaps the cohesion of water might begin to be an issue for survival, but my fics never go down to this scale.

Another factor in any gt story is ‘suspension of disbelief,’ a term embraced by all science fiction writers. Certain parts of gt are not supportable in the real world, no matter how much we wish it so.
