I thought of an integer between 1 and 100.

How many yes-no questions do you need me to answer so you find this number if you don't want to rely on luck?

What if you have to send me the full list of your questions first? How many questions will you need then?

How long is your list of yes-no questions if you know that I will forget to answer one of the questions?

(You will see which question is unanswered in my reply.)

I think this is a nice & playful way to introduce children to binary (and hint on error-correcting codes).

I swear I didn't know what @3blue1brown was working on
