I thought there was a relatively good explanation for ice spikes having to do with the volumetric expansion of water as it transitions phases from liquid to solid. Basically as an ice cube freezes there is a shell formed over the top surface and under the right circumstances it forms from the outside edges in leaving a hole, but then instead of the hole closing over ice starts forming downward into the bulk of the cube, pushing liquid water out of the hole which is then frozen into a protrusion
Even so, each individual button needs to be connected to that PCB separately, and will only have the function of what it says on the button, or possibly a couple hidden functions through programming.
Touch screens are essentially one connection for infinite buttons with different screens and menus.
As hugin said, the best way to wash oils off your hands is with other oils. Pour a little bit of whatever cooking oil you have on your hands and make sure to thoroughly spread it on your hands, like in between your fingers and under your nails, then wash with hot water and soap. The capsaicin oils will mix with the cooking oils, dilute, and be more noticeable to remove. This also works for poison ivy oils and pine sap
One of the things I've read about why things are the way they are is a comparison to probabilities, the thought is that similar to how there is one and only one way to roll a bunch of dice and have them come up all ones, there would be one and only one way for there to be "nothing" in the universe given the existence of any energy because of how many different ways energy can exist it's much more probable that you get a jumbled pile of all kinds of different things.
Now as for the question of "where did all this energy come from" you have to realize that even the vacuum of space contains energy of some level and the 'visible universe ' that is all of the matter that interacts with electromagnetic fields only accounts for a tiny fraction of the total energy we can detect so it's likely that the energies that make up our matter and universe came from "somewhere else" ... but then where did that energy come from and then it's turtles all the way down
When my dogs are asleep and clearly dreaming they'll make little noises and twitches like they're running and barking in the dream and little bits of it make it to the surface
I want to add Adventure Time to the good list. There definitely are some episodes that feel "lol random" but there's a longer story arc that's actually really deeply explored
Wife and I have been watching Foundation. season 1 felt really good but season 2 has continued to have moments that make us go "Wait what? That's not how that works." Or "You're just going to say/do that without any further explanation?"

The dude who can freeze time (framed as him imagining) isn't the one adding dildo shaped shampoo to women's grocery carts to see if they'll buy it when the get to the checkout. He just uses his time powers to, ahem, artistically admire women's naked bodies when they're grocery shopping and unaware they're being the subject of his drawing
The lights are also so others can see you, not so relevant when you're really out away from civilization but there are many laws that require headlights to be on when windshield wipers are used
While this does prevent the oxidation of the molten weld metal it doesn't prevent discoloration from the vapor deposition on and around the weld, or slight oxidation from the hot metal as it exits the shielding gas cloud. Paper is less prone to this kind of oxidation but even welding on a vacuum can still produce some discoloration from the vaporized material
