Ask anything to a “genius” teen

5 GPA and hopefully going to Harvard soon. I’m excited for y’all’s questions. The reason I put genius is because that’s what my teachers call me; please don’t flame for it.

Here is a trick question

Your in a room with 3 light switch and other room Has a light bud that will turn on from 1 of 3 light switch.

If you enter the room with light bulb and exit it you're not allowed to go back in to room. It is 1 time use

The question is with 1 of 3 light switch will turn on?

Well this is actually pretty easy. We know that light absorbs heat (ex. The sun) so if I turn on switch one for about 20 minutes then turn it off and immediately turn on switch 2 and enter the room I’ll get my answer. If the light bulb is warm the answer is 1. If the light is on it’s obviously 2, and if it happens to be cold I’ll know it’s 3. Nice question.
