Railway Track Illusion

This marvellous effect is based on an optical illusion first described by Joseph Jastrow in 1891.

Provided are:

A) Two quality wooden train tracks

B) Detailed sheet of instructions.

C) Sheet with 2 Pair (4) Printed Railway Track Sections.

Once the principle is understood, many other similar objects can be used to replicate/demonstrate this effect.

e.g. In my shows, I often use coloured pieces of cardboard and invite a spectator to rub the cardboard and demonstrate how it can stretch and shrink with ease!!
