Can you solve this?

Lateral Thinking Puzzle No. 1

You are in a two-storey house where DOWNSTAIRS, there are three light switches.

Each switch controls one of three light-bulbs located UPSTAIRS, but you don't know which switch controls which light. (As you might expect, you cannot see the light-bulbs from downstairs!)

What can you do so that you need to go upstairs just ONCE to determine which switch controls which light?

You haven't said whether there's someone else in the house! In which case, you switch on one light and send them up to see which room it's in. Then you can switch a second light on and go upstairs yourself!

I'm afraid you're completely alone in this house but your answer does demonstrate lateral thinking! Keep going!

Beattie Oh no, I'm supposed to be gardening - oh dear!

Turn on one switch when it’s dark. Go outside and check which light is on upstairs. Do it again. This way you shouldn’t need to go upstairs even once if you’ve remembered the switch order.

I suspect this is not the answer you are looking for!

Top line has hard lines.
Bottom line has curved lines.

Well done on 'CROSSROADS'!

Now it's your turn to come up with a puzzle! (Oh, didn't I tell you that was in the rules? Silly me!)

Very perceptive but I do like your answer to the lights puzzle!

The more correct procedure may be carried-out at any time of the day (you don't have to wait for darkness or go tramping around outside, it might be raining!)

With regard to the Observation Puzzle No. 1, CORRECT!

Your prize is for you to submit a puzzle!

Go and enjoy your gardening in the sunshine! The puzzles will still be here when you've finished!

Found this one in a Christmas cracker!

What might you expect to find in a bottle with the label:

'H-I-J-K-L-M-N-O' ?

Pure water Beattie (Or H2O)

Light bulb - just turn two on at once!

Won’t be setting any quizzes (rule breaker), but will enjoy trying to answer them. ?

No, that won’t work.

Switch on #1 and #2, leave #3 off
After a few minutes, switch off #2
Go upstairs
The bulb for #1 will be on
The other 2 will be off, but #2 will be warm to the touch. Don't burn yourself :-)

yggdrasil You've just beaten me to it - I thought the same!

Correct! Did you buy the same box of crackers as me?

That's the answer!

Since incandescent lamps (e.g. tungsten) have an efficacy of around 2-3% only, as light sources they make better heaters!

Anyone in the mood for another brain teaser?

In the film, 'Die Hard - With A Vengeance', Bruce Willis's and Samuel L Jackson's characters are given riddles to solve by bad guy, Jeremy Irons.

Many of the riddles are not worthy of mention here except perhaps, the one where they have to measure precisely 4 gallons of water using just two containers, one of 3-gallons and the other of 5-gallons capacity!

The solution offered in the film seems rushed and a bit ambiguous, so I wouldn't bother watching it right now! (And in any case, that would be cheating, wouldn't it?)

But I can tell you that there are two methods of achieving the 4-gallon goal!

Over to you!

Here is today's puzzle.

It's another Observational or Gestalt (if you prefer) problem!

And something else for you to think about whilst the above puzzles are being worked-on by your sub-conscious mind:

Imagine you are having a telephone conversation with someone who never seen or experienced any of the following:

a banana
a magic-wand
a Toby jug
a die (as in dice)
an elephant

The object of this exercise centres on how descriptive you can be using words/speech only such that the person to whom you are speaking will recognise the item beyond all reasonable doubt, when they see it.

Naturally, there is no one correct answer for this exercise, but it may generate some interesting responses on the forum!

Feel free to suggest other items to be described!

Fill the 5 gallon container and pour it into the 3 gallon. This will leave 2 gallons which you then pour into whatever you are supposed to be measuring 4 gallons into. Then do the same again.
