The world’s first mind reading tee shirt is back!


A few years ago we created the world’s first mind reading tee shirt. They were only available for a very limited period of time.  Well, the good news is that they have just relaunched and are available for the next 4 days.  Here is a video about it and the links. Enjoy!

and the video showing this ground-breaking invention in action is here:

How to keep your New Years Resolutions


new-year-s-resolutionsIt’s that time of the year again. Right now millions of people will be making their New Years Resolutions in the hope of creating a new and improved version of themselves.  I am all for it. However, my work shows that only about 1 in 10 people will make their dreams a reality. Why? Because we often don’t know how to change our habits.

In 59 Seconds  I describe a large-scale study that I carried out into the techniques used by people who managed to make change stick.  Here are my 10 top tips, and a little video….

1) Make only one resolution, your chances of success are greater when you channel energy into changing just one aspect of your behaviour.

2) Don’t wait until New Year’s Eve to think about your resolution and instead take some time out a few days before and reflect upon what you really want to achieve.

3) Avoid previous resolutions; deciding to re-visit a past resolution sets you up for frustration and disappointment.

4) Don’t run with the crowd and go with the usual resolutions.  Instead think about what you really want out of life.

5) Break your goal into a series of steps, focusing on creating sub-goals that are concrete, measurable, and time-based.

6) Tell your friends and family about your goals, thus increasing the fear of failure and eliciting support.

7) Regularly remind yourself of the benefits associated with achieving your goals by creating a checklist of how life would be better once you obtain your aim.

8) Give yourself a small reward whenever you achieve a sub-goal, thus maintaining motivation and a sense of progress.

9) Make your plans and progress concrete by keeping a handwritten journal, completing a computer spreadsheet or covering a notice board with graphs or pictures.

10) Expect to revert to your old habits from time to time. Treat any failure as a temporary set-back rather than a reason to give up altogether.

Oh, and if you want to utilise the power of visualisation….

The Transparent Man: A new Quirkology video


Magician Robert Harbin performing his Zig Zag illusion

The lovely folks at Google Making & Science recently asked me whether there was a science-based project that I would love to make happen.

A few weeks before, magic consultant David Britland had drawn my attention to a little-known optical illusion from the 1920s called ‘The Transparent Man’.

The illusion was described in a book written by magician Robert Harbin, and involved just a few sheets of glass and a light. According to Harbin, if everything was arranged in a certain way, a person would appear transparent. It’s an amazing idea, yet no-one had actually built the illusion to see if it worked.

When I looked at the plans, I realised that Harbin’s illusion used the same general idea that’s currently employed by physicists trying to make objects invisible! I contacted the world’s leading expert on invisibility – Professor Ulf Leonhardt – and asked if he would like to be involved in the project.

Ulf was amazingly generous and recorded an interview about this little-known optical illusion, his research into invisibility, and how Harbin’s illusion was years ahead of its time. In addition, magician Scott Penrose (President of The Magic Circle and a huge fan of Harbin) kindly agreed to be interviewed about Harbin’s most famous creation – the Zig Zag Lady.

The illusion took a long time to get right because it is a bit of an optical nightmare, but eventually the Quirkology Ninja and I managed to pull it off.

Here is the short documentary showing the illusion……

And here are the related interviews by Ulf and Scott….

Loads of people were kind enough to help with the project, and so my thanks go to…Professor Caroline Watt, David Britland, Professor Ulf Leonhardt, Joe Pavlo (I still have no idea how you did that), Mat White, Scott Penrose, Darren Martin, The Magic Circle, Jim Steinmeyer, Cameron Watt, Peter Lamont, Helen Keen, Simon Gage, and Sarah Angliss.

We have just launched a Quirkology Mind Games set!



For the past year I have been working with the good folks at Marvin’s Magic to create a Quirkology box of goodies. The exciting news is that today we are launching Mind Games at the QED conference and online everywhere.

The set is crammed full of jaw-dropping illusions, surprising science stunts, and bets that you will always win. And all with a quirky twist. Within a few moments of opening the box you will appear to move objects with the power of your mind, transform anyone into a zombie, defy gravity and lots lots more. The box contains everything you need to astound your friends and family, and even has a specially filmed Quirkology DVD. Have fun!

Available at Amazon UK UK here.
Available in the UK, US, Europe and Canada here.

With huge thanks to Marvin’s Magic, Water Closet Press and QED.

A little pile of (mostly unwanted) things.


jastrowjA few days ago I visited the Joseph Jastrow archive at the David M. Rubenstein Library (Duke University, North Carolina).

Jastrow is one of my favourite psychologists, and I have frequently been inspired by his work. Born in 1863, he built America’s first psychology laboratory at the University of Wisconsin and investigated several intriguing topics, including dreams of the blind, optical illusions, and the psychology of magic. His work laid the foundations for modern-day psychology and two of his illusions – ‘Duck/Rabbit’ and ‘Boomerangs’ – still appear in most psychology textbooks.  Jastrow was also passionate about popularizing science and regularly gave public lectures, wrote newspaper articles, and broadcast on the radio.


I visited the archive in the hope of learning something new about his life and work. The staff were very friendly, and kindly allowed me to look through all the great man’s letters, scrapbooks and photographs.

The letters provided a fascinating glimpse into Jastrow’s personal life. In one box I found a letter from Jastrow containing a light-hearted description of himself – ‘Will wear any kind of clothes and eat anything…Is a good deal of a nuisance but doesn’t mind being told so’.  In another box I came across a small card tucked inside a diary.  Jastrow had created a clever little joke about Hitler and typed it up – I suspect no-one had seen the joke for over 50 years.


And then I came across the final letter in the archive.  At first, I didn’t understand what I was looking at.  The letter was dated 1944, contained a short list of Jastrow’s possessions, and asked recipients if they were interested in any of the objects. ‘A wool coat’ (‘English worsted, navy blue’), ‘4 pairs of spectacles’ (‘Can any one use the rims?’), ‘a curious collection of hand-made collar pins’,  ‘a signet ring’ (‘Unsentimental though I pretend to be, I should rather like to keep it’).  And then the penny dropped. Jastrow had just died.


In life he investigated the dreams of Helen Keller, was a personal friend of Harry Houdini, and created a complex psychological profile of Adolf Hitler. In death Jastrow was reduced to a little pile of (mostly unwanted) things.

Feeling somewhat sad, I started to look through the photographs in the archive. Once again, it was the final item that caught my eye. Right at the back of the last box was a wonderful photograph of Jastrow sitting by a radio microphone. I have never seen the image before and I think this is the first time it has been made public. I love the photograph because Jastrow looks so relaxed, absorbed and happy. He is doing what he loved to do, and did so well.  Sitting there resplendent in his spectacles, collar pin and signet ring.


The whole episode felt like a momento mori – a brief but striking reminder of the importance of enjoying life because soon we will all be reduced to a small pile of (mostly unwanted) things.

And that’s what I learned in the Jastrow archive.

A new Beuchet chair illusion


I have always been a huge fan of the Beuchet chair illusion. Created by psychologist Jean Beuchet in the 1960s, this wonderful illusion is used all over the world to make people appear to be tiny.


There is, however, one small problem from a practical perspective. The illusion involves building a large chair back and seat, and a carefully crafted chair base.  When I was working on items for the Quirkology exhibition I wondered whether it might be possible to create a much simpler, and more portable, version of the illusion.

After endless trial and error I realised that the same effect could be created with a small cut out of a chair and a piece of cloth!

Here is my chair in action and a reveal showing the size of the chair. It took a huge amount of time to create just the right shape of chair, but the illusion works well, can be made for just a few pounds, and is ultra-portable.


And here I am using the illusion whilst being interviewed about the exhibition on STV news…


I have used it several times and if you want to re-create the piece for a project, feel free to get in touch!
