It's not just one of the oldest, it was THE Very First Chewy warehouse. It was in a dire state of decay and I'm honestly surprised they let it limp along as long as they did. It was originally a tank factory, then an ice cream factory, then Chewy bought it. The building has run its course. The Lewisberry facility is awesome and will be absorbing any of the workforce who wish to transfer, nobody will be laid off or demoted.

There are always exceptions. For every rule there is some weird circumstance or extreme condition that breaks it. Our rules are constructed out of convenience because they fit basic circumstances and help us to learn.

When teaching chemistry we tend to teach a bunch of rules and then later teach the exceptions, because it's easier to understand the exceptions after you have the necessary base of knowledge.

Infrared and red laser pointers are direct laser diodes (put current in and light squirts out). Green and blue laser pointers are made by using an infrared laser diode to pump a nonlinear optical crystal which doubles the frequency (halves the wavelength... however you want to say it) to put out photons with a new color. That doubling leaves a gap of wavelengths that are more difficult to access.

It absolutely can and does create a seal strong enough to keep the gas contained. Note the inside of the bottle cap, it has a rubber gasket which is pressed against the lip of the bottle mouth to create a seal. Furthermore, this seal doesn't have to resist as much pressure as you might think, most of the carbon dioxide is dissolved in the liquid, the cap only has to contain the pressure in the small head space enough to shift the equilibrium toward dissolved CO2 over gaseous. Same as with soda bottles.

It's their revenge on you for cutting them. But seriously, it's meant to deter things from eating them. Which of course is one reason we (as humans) eat them, because humans are weird and we sometimes like pain. Kinda like hot peppers, they got spicy to discourage anyone but birds (who can't taste spiciness, and are the best seed spreaders) from eating them. But that kinda backfired in the case of us weirdo humans.
