I have a friend in office who posts some amazing facts on his white board. I have always marveled at some of the crazy facts he knows. Here is one:

1. A rye plant’s root is around 400 miles (650km) long. That is just unbelievable!!!

Here are a couple that somebody else had told me.

2. A crocodile’s digestive juices are so strong that they can digest a nail !! That is why it does not matter that they cannot chew – or for that matter even move their tongue!!!

3. That thing we call “paper money”? – it is not made of paper. Most currency bills in this world are made from – get this – cotton!!! (sometimes a mix of linen and cotton)

Here is one for you to guess and then perhaps Google.

There is only one mammal in this world that cannot jump. Can you guess which one? (BTW, regardless of what that movie title would have you believe, “white men” is NOT the answer 🙂 )

After flying to San Francisco on Monday, flying back to Atlanta on Tuesday and then to DC on Wednesday, I have no doubt that I will sleep off on tomorrow’s (Thursday) early morning flight. So, I figured I might as well post the puzzle tonight and go to sleep.

Pardon the picture – I put it quickly on my iPad app. But here is how it goes.

Six coins are arranged in two rows like in the picture on the left. In three sliding moves, you have to get the circular arrangement on the right. The rules are – (*) you can slide only one coin at a time (*) you cannot “push” other coins away when you move a coin – and of course no lifting the coin off the surface either (*) here is the interesting one – when you move a coin, you have to make sure that when you leave it in its new position, it has to touch two other coins.
