In fact you can use your smartphone to change the channel on nearly any TV. In the comments on that post some people talk about how to do it. Basically you need a smartphone with either builtin IR or use a USB-C IR blaster or if your phone has a 3.5mm headphone jack you can also try one of those but I’m not sure if the 3.5mm ones are as commonly supported.

    To act as a fuse, the tab needs to reach 660 degrees celsius, and if the breaker pops, that means the breaker acted as the fuse.

    I can tell you from experience; both occur.

    Such a thin piece of aluminum across 120vac super heats so quickly that it basically vaporizes, faster than the breaker can react. That metal vapor allows an arch to form still passing excess current which is what finally trips the breaker. (standard breakers take time to trip, longer than fuses in many cases; this is intentional design. GFCI breakers are a different story.) Sometimes this arc doesn’t form and the breaker doesn’t trip; but it usually does.

    Once tripped, the vapor has time to dissipate so the short clears and the breaker can be turned back on.

    None of this is advice. Someone asked about dumb pranks I’ve pulled in school. I’m just discussing the past; not making recommendations for the future.
