Difficult to give a hint without giving it away...

concentrate on:

"no cracks, doors, windows, or vents"

or if I rearrange it as:

"no doors, windows, vents, or cracks"

There is only 1 way to use 7 plus or minus signs in between the digits 1-9, in order, to make the following correct:

1 +2 +3 - 4 +5 + 6 +78 + 9 = 100

What is the way to do it with ONLY 3 plus or minus signs?

This is a bit more up my street Rod.

123 - 45 - 67 + 89 = 100

:bounce:

Will refrain from posting my new one until tomorrow some point.

I think Div's needs to stand - got me scratchin' my head at the moment.

I assume all open - so nothing to stop smells getting to you. :?:

Correct - there ARE no doors, windows or vents - just spaces where they should be.

DOH!!!!!!

DOH!!!!!!

as you can probably tell - I prefer the more logical type puzzles.

Still... good one Div!

Old one I know.

Using

a tap

a three pint container and

a five pint container,

can you measure exactly 4 pints?

[Div]

OK:

1. Fill the 3-pint container and empty it into the 5-pint container.

2. Fill the 3-pint container again and fill the 5-pint container.

This leaves you with 1-pint in the 3-pint container.

3. Empty the 5-pint container.

4. Now empty the 3-pint container (which only contains 1-pint) into the 5-pint container.

5. Fill up the 3-pint container again and add it to the 1 pint that's already in the 5-pint container, giving you 4 pints.

Ok, here's one that get's me in stiches - especially if you tell it whilst slightly tipsey!:

If the day before two days after the day before tomorrow is Monday, what day is today?

[Matthew_McNally]

Friday?

or at least it is on the day I posted this.

[Div]

To be honest I don't actually know the answer - However I do not think that today's day is the correct answer.

You are imprisoned in a prison cell.

This cell is fifty foot tall - but is on top of a 105 foot tower.

You have managed to get the bars off the windows - but still have to worry about that drop!

Luckly, in the ceiling of your fifty foot tall cell are two rings, about a foot apart.

Fifty foot of rope hangs from each of these rings.

Now, the confinement in prison has weakened your bones - so you really can't fall more thana few feet without risking serious injury.

But luckly there is nothing wrong with your climbing ability. :smilegrin:

Armed only with your trusty pocket knife, how can manage to cut enough rope to allow you to safely descend from the tower?

[Rodders_UK]

Cut down one of the ropes and hang it over your shoulder.

Climb down the other rope until you are standing on top of the tower.

Then cut that rope as high as you can reach.

Tie the two ropes that you know have together.

Tie the newly joined rope to the tower.

Climb down the rope.

Sorry Rod - but the ropes are hanging from a fifty foot high ceiling.

Will look at revising puzzle to make sure this is clear.

[Rodders_UK]

okay okay, so you do as I said AFTER you've climbed up one rope to cut the other rope down from the top

still don't think that will cut it Rod - sorry.

You get 50 foot over your shoulder and climb down?

Then cut the next rope as high as you can reach - say 10 feet?

This gives you sixty feet, and you are facing a 105 foot drop!

;)

[Div]

OK - I think I got this one nailed - You unthread it and weave the rope into an overly elaborate parachute?
