Hints / Solution 1. Forget about the wooden block. 2. Arrange the nails in a symmetrical pattern. 3. The first nail goes in this direction. • The second nail goes downwards like this. • Continue the symmetrical pattern • leaving one nail spare. • The last nail goes in the opposite • direction to the first. • Finally, holding both ends, • carefully lift up all the nails and place on the single nail. You will need to get the ‘feel’ for the balance point. Created by Mr Lafferty www.mathsrevision.com
