So what if the last two aren't a whole number? My brain won't allow me to remember a number specific trick if it's only applicable a portion of the time. For example, 9 finger trick works every time.

You should do this as a series with the other divisiblty rules - the kids “learn this” but don’t really understand. Your videos would be way more fun than “teaching” them to the kids 🤩😂

the divisibility of any exponent of 2 is if 2^n you check the last n digits

Does this work for any other number? like if the last two numbers are divisible by 7, the whole number is aswell? If not, what makes 4 special?

There are many divisibility rules. Some are obvious, others not.
Obvious: 1, 2, 5, 10
Not obvious...
