    Good one. All 15 solutions are good even if some riddle might have other answers. The only miss here is in the bonus.
    To drive to the video's conclusion we have to assume too much, specially as if all 3 men act as no-brain automaton. So there are only that much situations where 3 men placed like in the picture will bring the middle one to work harder than each of the others. In practice the deduction in the video is improbable. If the man in the middle works harder, he will tire faster and so try to diminish his effort which leads to the other to work harder than the middle one... and back and forth in this balance they will finish by work equally hard... if the workload is supported long enough. In fact, the real work done by each will be proportionate to his own real capacity of work after a balancing back and forth the effort between all three men assuming there is enough time of work to allowed the equilibrium to be reached.

    Hi, I just want to point out in the ice bucket question that I think you might be confusing some school students. At 32 degrees Fahrenheit the water is "turning" into ice, not at 25 F. The script implies that water freezes at 25 F. Twenty-one million subscribers, such as myself, are counting on you folks! (put happy face imoji here LOL!) I always enjoy it when you produce a "can you guess" segment such as this one. Cheers!

    You'r not in a shower unless the water is running. You can go into the shower booth, but it's not a shower unless the water is running. You can't go out into the rain on a clear day either. Same principle.

    1st I kinda guessed it, I thought the girl didn't even light the candle. 2nd guessed it. 3rd I don't know about farrenheit temperatures but the only idea I had was correct so I guessed it. 4th I overlooked the simple math but I did eventually guess it. 5th I first understood it wrong and though only one person must see the apple but then I read it again and guessed it. 6th guessed it right away. 7th didn't guess because I forgot I have to read the whole thing if I get stuck. 8th guessed it. 9th didn't guess. 10th I almost got it but too late. 11th guessed it was light but didn't guess he bought a candle and matches so I count it as half a point. 12th guessed it. 13th guessed it. 14. even though it was simple I didn't guess it. 15th also didn't guess, I'm not into cars. BONUS I didn't know the physics of it but the middle man was the one I guessed. So 9.5/15 +1 points, not bad for my age (13)
