Much taller than those trees,
Up and up it goes,
Still it never grows?

This is a classy optical illusion puzzle. What more you can find except bricks in the image below?

I was speeding and ran through a stop sign, yet two traffic officers who were there do nothing about it.

why?

I ask Joseph to pick any 5 cards out of a deck with no Jokers.

He can inspect then shuffle the deck before picking any five cards. He picks out 5 cards then hands them to me (Jack can't see any of this). I look at the cards and I pick 1 card out and give it back to Joseph. I then arrange the other four cards in a special way, and give those 4 cards all face down, and in a neat pile, to Jack.

Jack looks at the 4 cards i gave him, and says out loud which card Joseph is holding (suit and number). How?

The solution uses pure logic, not sleight of hand. All Jack needs to know is the order of the cards and what is on their face, nothing more.

Sherlock Holmes was challenged to make a pre-drawn line smaller without erasing it. He did it in fractions of seconds. How?

When I divide it by 5, the remainder is 4.
When I divide it by 6, the remainder is 5.
