Your answer is. Thanks M Ordway. Draw three houses in a horizontal row. Draw three utilities suppliers beneath them: Gas, Water, Electicity. You should now have six points or boxes on your sheet of paper or flip chart. The challenge is to connect each house to each utility supplier without any of the nine connection lines crossing.
Think of a number between 1 and Multiply it by 9. If you have two digits add them together. Subtract 5. Think of a country that begins with that letter. Think of an animal that begins with the second letter of that country. Thanks R Corovic. Do this sum in your head: Start with 1, Add Add 2, Add 1, You need just a few grains of salt.
Make a tiny pile of salt on a flat surface and balance the egg on the pile. Then carefully blow away the excess salt, leaving just the few grains actually supporting the egg. Obviously this needs preparing in advance - if pressed to repeat the trick, place the egg down hard enough to break the shell, which will also enable it to balance. You can prepare a banana so that when someone removes the skin the banana inside is already sliced:. You need just a clean pin. To make each slice, insert the pin through the banana skin, but not so deep as to enter the skin on the other side.
Move the pin sideways in a see-saw motion, using the entry point of the skin as a pivot. Replace the banana in the fruit bowl. A more sophisticated method is as follows: Use a needle and thread rather than a pin. The aim is to thread a loop around the banana under the skin for each slice required.
Consider the banana skin to be composed of several angled facets. Insert the needle at one facet join where you wish to slice it, and bring it out at the next, so that the thread runs under the skin. Re-insert the needle in the same hole and go along to the next join and so on. Eventually bring the needle out of the original hole. There is now a loop of thread all around the banana under the skin. Hold both ends and pull gently. The banana is sliced through using the cheese-wire principle. Repeat the process for each slice.
Thanks Michael Green. If you haven't guessed yet here's the answer and a few more details. Six friends visited their local club to play at a pool tournament. There were no other prizes. None of the friends won a single game. Adapted from a puzzle from Alex Sallustio, thanks. Write down any three-digit number, with different first and last digits.
Reverse it. Subtract the smaller number from the larger one. Write down the answer. Reverse it including the zero at the beginning if less than a hundred. Add together both numbers. Your final answer is. This fantastic lateral thinking puzzle makes a great quick warm-up. It will also win you a fortune in pubs and bars the world over. It is essential you practice this before using it in front of an audience. The challenge is simply to balance 14 nails on one single nail which is fixed upright in a block of wood.
The nails must all be the same size - any length provided they have flat heads. The suggested scenario is that due to a last-minute hitch where you are exhibiting your products nails , you your team have just say three to fifteen minutes to devise a way of displaying all 14 nails using only the single fixed nail as a support. None of the other 14 nails can touch anything other than the other loose nails and the fixed nail.
Teams of three are good for this game as it's high-involvement, trail and error, and hands-on; more than five per team will cause people to be left out. Issue each team with fourteen nails and a block of wood with the fifteenth nail hammered into position.
Different types and lengths of nails may change the number of nails required, but there must always be an odd number including the fixed nail. Thanks to John Rivers for this great puzzle. This is an old fairground game, but can you calculate the mathematical chances of winning with a single go? To win, you must toss a 1 inch diameter coin onto a chequered board comprising 2 inch diameter squares; the coin must come to rest entirely inside a square, not overlapping any other square. Thanks DC Answer.
Everyone's seen this shape before, but there's more to it than first seems. The Necker Cube provides a fascinating demonstration of how the brain works on a sub-conscious level whether we want it to or not. Stare at it for a few seconds and it will flip into its alternative perspective. Wait and it will flip back again. It's unlikely you'll be able consciously to change the perspective that your brain chooses to see, although blinking might trigger the brain to 'refresh' the image.
How do you stick a knitting needle through both sides of an inflated balloon without the balloon bursting? This works on MSExcel 97 if you can still get hold of a copy. Start program. Press F5.

The boat will only carry him and one of the things at a time or it will sink. Without the farmer, the dog would kill the chicken, and the chicken would eat the grain. How does he get all three across safely to continue his journey? Take an empty beer bottle and a small coin which is wider than the mouth of the bottle but no wider than the rim a British penny is ideal.
How do you move the coin without moving the bottle, touching or blowing the coin, or using another object to contact the coin and move it? You need some string or cord that's normally impossible to break with bare hands. Cut a ft length. Wrap one end clockwise three or four times around the base of your left thumb to secure it. The loose end should hang from the back of your thumb, not over the front.
Drape a large loop across your left palm so that the loose end hangs over the back of your hand between your left hand thumb and forefinger. Bring the loose end underneath palm and feed it up through the bottom of the 'U' of the loop, from the back to the front. Pull and tighten string, so that the crossing point is in the centre of your palm, keeping left hand firm in a karate-chop position. Wrap the loose end firmly around your right hand. Pull sharply down with right hand, keeping left hand firm.
The string will be cut at crossing point. Left-handers obviously reverse positions. Depending on your strength and confidence you'll be able to cut extremely strong nylon cords this way. The point of the trick is to demonstrate how innovation and positive approach can achieve the seemingly impossible. There is more computing power in a happy birthday sound card than the whole world in Source - Innovations magazine Do not show the audience this preparation Start with a paper rectangle, any size, 9" x 6" is fine.
Make two right-angle cuts to the exact centre on one long side, at 3" and 6". Make one right-angle cut to the exact centre on the other long side at 4. Lay the sheet flat, fold over the central flap making a neat hinge and fold it back. Lift the sheet by the two short sides, with the flap away from you, and twist one of the L-shaped ends degrees half a full turn. Lay the sheet flat again, and fold the flap down both ways to create a hinge.
The flap should now be erect, with half of the cut-away on each side - which looks like an impossible construction. This is what you show your audience. Ask them to explain it. Read out at normal pace the colour of each word, not the word itself, without making a mistake. Anagrams never lie. Particularly good fun if you use work-colleagues' names - and amazing how often really fitting anagrams crop up. An amusing diversion during meeting breaks if you're using online projection equipment.
Anagram finder - online and free - great fun for meetings and training sessions. Try this for yourself. If you do it with a group use a flip chart. Draw a circle. Divide it into two equal parts, answer is obviously one line dissecting across the centre. Next draw an equilateral triangle three sides same length and divide into three equal parts.
Think about it before you read on. Answer is tricky for some - three lines from centre outwards to corners. Next draw a square and divide it into four equal parts easy - two lines dissecting up and across to make four quarters.
Now draw another square. Divide it into five equal parts. The point is to demonstrate how the mind can get 'stuck' in a certain thought pattern. Got it yet? Ask the other person to write down a 4 digit number. On a separate piece of paper write a 5 digit number which you secretly arrive at by putting the number 2 in front of the other person's 4 digit number and then deducting 2 from the five digit figure.
For example if they write , you would write If they write , you write Do not show the other person the number you have written on your piece of paper, instead fold it to conceal the number and give the folded piece of paper to them to keep. Ask them to write another 4 digit number beneath their first number.
You then write a 4 digit number beneath the second four digit number so that the total of the second row and your new third row is eg. NB If their first digit is 9 don't write any number in the thousands column, or it may give a clue as to your method - see example below. Do not explain your choice of numbers to them. Next ask them to write another 4 digit number beneath the three other numbers.
You now write another 4 digit number beneath it using the same rule; ie. You should now have five 4 digit numbers, one above the other. Ask the other person to add all five rows and write the total beneath them. Ask them to look at the number written on the folded piece of paper that you gave them earlier. It will be the same as the total they've just calculated. You can extend the trick to seven rows deduct 3 and put a number 3 in front of the first number , or nine rows deduct 4 and put a number 4 in front of the first number , and so on.
This is the specification for the most incredible, sophisticated planning and communications tool yet invented: It's portable - so light don't even notice it your pocket or brief case. Its life is more than one-hundred times greater than the current best re-chargeable power-packs.
It is extremely durable - if dropped from 50 feet onto concrete it'll be good as new within a minute or two at the longest. It's so intuitive that anyone can use it immediately without training.
You can use it on a plane - even during take off. It uses a remarkable data input method as fast as an experienced qwerty keyboard operator, and yet requires no keyboard skills. It handles graphics as easily as text and can even handle 3-D modelling and complicated calculations. It is compatible with any paper output, even a bus-ticket or a table napkin, and is universally adaptable to any reader format. It is completely wireless, already available all over the world, thanks to a distribution network greater than Microsoft's, and comes in hundreds of model variants to suit all styles and egos - you can even get gold-plated ones.
It costs a fraction of a penny per day over its lifetime, and if you lose it, its inherent unbreakable security will leave no trace of confidential files or personal history. Replacements are no problem because you can afford to keep a couple spare with you all the time.

If anyone can send a photograph of this word on a sign at the Hoover Dam - please email it to me. Very rarely will anyone consider building four triangles in 3D three-dimensional as a pyramid. Answer: slide the middle stick a half-stick-length right or left , then move the top now unconnected stick to the opposite downward corner to make the new shovel.
The puzzle is difficult because most people naturally imagine moving sticks to entirely different positions, and rarely consider shifting a stick only half of its length. A slashed 'equals' sign is the mathematical symbol for 'does not equal'. Given strict application of mathematical rules for the order of calculations - see BODMAS - the above solution can be reduced as follows, because the rules dictate the multiplication be calculated before the addition:.
Becky explains the BODMAS effect: because of order of precedence the multiplication of 8 x 9 occurs first resulting in 72; the other numbers add up to 28, which when added to 72 makes This is a lateral-thinking solution if the question is taken to imply that each digit stands alone, but it's another option, depending on how strictly the question is interpreted.
Again the solution must be employed with the BODMAS sequence for performaing the different calculations, which in this case means multiplication first, then addition, then subtraction. And a further brilliantly simple and elegant suggestion thanks D Jackson. Here below is a fresh approach, and a wonderful example of lateral thinking thanks V Chaves. The validity of the solution depends a broad interpretation of the word 'formula' in the question. It certainly uses very few symbols and the mathematics are difficult to dispute:.
Here are a couple of solutions thanks R Von Der Emden based on a very clever lateral thinking approach:. Read our other blogs in the Impact Lab such as:. How to set up a successful remote workshop.

Here are some examples of matching prompt questions to participants: Your team: Draw a picture of your breakfast and show it in the video. Some of Our Favorite Warm-Up Questions You can also create great warm-ups by asking a good prompt question, giving everyone a moment to think, and then going around and giving each person a bit of time to share their response.
A few of our favorites: What was your first concert? What is something you are really in to right now? The goal is to increase the speed of the transfer over time through the memorization of each participant's name. The game can be played with a set order or randomly.
In Zoom, participants are given a series of pictures that, when placed in proper order, form a sequential set. The goal of the activity is to get participants to line up according to their pictures in the proper sequential order -- without revealing their photos. Each member is given one or two pictures and the team is required to work together to decide in which order participants should line up, but they can only communicate through an oral description of their picture of pictures.
For this game, each participant receives several tokens and moves about the room talking to other participants. Each member asks questions to the others, but no one is permitted to respond "yes" or "no" to the questions.
