It’s the Friday Puzzle!

A friend of mine has 10 sheep, and they insist on standing in a circular pen like this…..

However, it turns out that all of the sheep don’t like one another, and so have also insisted that they are protected from each other by a wall.  The problem is that sheep pen walls are circular, and my friend can only afford three of them.  How can you draw three circles on the illustration to ensure that each of the sheep has its own space, protected from the others?

As ever, please do NOT post your answers, but feel free to say if you have solved it and how long it took.

Can you explain this ghost photo?

A few days ago I received this photo apparently containing a ghost. The person wrote (I have paraphrased this a bit):

“This photo was taken at my home. My daughter was standing. We were playing “Pin the tail on the donkey”. I had just spun her. I was standing in front of her taking the photo, my sister is in the background sitting on the other couch and our dog is standing next to my daughter. There was no one sitting there (on the couch). You will see the image of my deceased boyfriend clearly sitting on the sofa and later surrounding my daughter. Please let me know what you think.”

Any ideas?

It’s the Friday Puzzle!

If you happen to be up at the Edinburgh Festival then I am talking about the psychology of luck (it being Friday 13th) today at 6pm.  Details here.

Impossible but true illusion

First, it would be great if you can spare 2 mins to take part in a new study on the psychology of presentations.  All you have to do is click here, and feel free to encourage friends and family.  Many thanks.

Second, here is an amazing illusion by Akiyoshi Kitaoka. The background to the orange wave appears different to the background behind the purple wave, but both backgrounds are actually white!

Let’s all play word association

Today is Sigmund Freud’s birthday.  To celebrate, let’s all get those repressed thoughts out in the open by playing a huge game of word association.  I am going to start by giving you a word….


….now, the first person to comment has to write the first word that comes into their head when they think of the word ‘forest’.  Then, the next person to comment looks at what the first person has written, and produces an association for that word (and, if you want, say why you think the word popped into your mind).

Let’s get hundreds of comments going and see where it all leads……

It’s the Friday Puzzle!

The Essential Magic Conference has now uploaded all of the videos from all of the sessions, and you can watch them for just $75.  It’s a bargain, go for it!  OK, to the puzzle…..

Yesterday I saw a drinks machine that had three selections – Tea, Coffee or Random (Tea or Coffee).  However, the machine was wired up wrongly so that each button does not give what it claims. If each drink costs 50p, what is the minimum that you have to put into the machine to work out which button gives which selection?

As ever, please do NOT post your answers, but do say whether you have solved it and how long it took.

See you Monday!
