So you�re Bored??

When he returns in the evening he gets into the lift and if he is alone he gets off at the fifth floor and walks up the stairs to the tenth floor. However if there is someone in the lift with him he travels to the tenth floor. Why? Also: A car is driving along the motorway at a constant speed when one of the wheels falls off. Assuming there is no rolling resistance from the road why does the wheel over take the car?

First one, the man is a midget and can't reach the 10th floor button.

2nd, it was a reliant robin drive wheel?

Ok People here's another Brian Teaser for you:

You are given 5 bags. There are 10 Coins in each of the bags. In four of the bags, the Coins each weigh 10 grams.  In the remaining bag,  each Coin weighs only 9 grams. All the bags and Coins look identical. You must  find out which bag has the lighter Coins.

The problem is that all the bags look identical and all the Coins look identical. You can use a scale, but it has to be a single-tray scale, not a two-tray balance scale.  Also, you may use the scale only once.

How can you find out which bag has the lighter Coins?

Puzzlers............Begin

Must have been a freudian slip...............

That's using the scales 5 times

regarding the overtaking loose wheel - was the car reversing and the wheel went the forwards direction?

it gets whacked by a big artic and bounced forwards past the car

Try these on for size.......

Slice the square into 4 identical sections that each have a caterpiller and a leaf, except one - she's on a  diet again!

Slice the rectangle into two sections so that you could make a square 8x8 without any holes.

Enjoy

right then!
motorway...
wheel off...
overtake...

The wheel came off, landed on/in a car in the overtaking lane

Trying to work out if it is necessarily a road wheel.

You need to stop the leak long enough to allow the rescue service to arrive, Scare off the shark and tow you back to shore. The boat captain, tries to radio the coast guard and asks you to stop the leak, he tells you that in his years of sailing the boat, he knows that the weight of 4 Gallons of water on top of the marine Ply is enough to slow the leak without breaking the glass. <span style="font-weight: bold;">The Challenge...</span> Try to make 4 Gallons, exactly, in one of the containers in order to slow the leak.

My son came up with this solution, is it correct also?

You fill the small bottle with 3 gallons and empty it into the large one,
then refill the 3gal bottle. Pour as much as poss of the 3gal bottle into
the large one and you are left with 5gallons in the large bottle and 1gallon
in the small bottle. Then pour away the contents of the large bottle and
pour in the gallon from the 3g bottle into it. Then you refill the 3g
bottle and pour that in too.

Voila - 4 gallons in the large bottle!
