If you've read my books or been on any of my courses, you'll know that one type of visual aid that tends to go down well with audiences is the use of objects or props to make a point. Two nice examples came my way recently, showing that even something as apparently unpromising as cutting up or brushing items of clothing can be very effective.
In the first one, Dr John Sentamu, Archbishop of York, took off his dog collar during an interview with Andrew Marr, and then proceeded to cut it into small pieces to illustrate what Mugabe was doing to the identity of the Zimbabwean people, ending by promising not to wear it again until Mugabe was gone.
In the second one, Barack Obama dismisses criticism from the Clinton camp by brushing invisible dust from his jacket - and the more he brushed, the more the audience applauded.
You can see both these examples by clicking below - and more on objects as visual aids in my books Lend Me Your Ears: All You Need to Know about Making Speeches and Presentations, London: Vermilion, 2004 & New York: Oxford University Press, 2005, and Speech-making and Presentation Made Easy: Seven Essential Steps to Success, London: Vemilion, 2008.
