The Silly Putty Ball has just bounced. |
|
|
| Abstract |
The familiar and fun properties of the complex fluid called Silly Putty or Tricky Putty are explored in a video developed by stage one students (first year university students).
|
 |
| Portable |
This is a portable demonstration that can be taken to schools.
|
|
| Principles Illustrated |
Silly Putty or Trick Putty is made of long chain molecules that can slide past each other on a long time scale but not on a short time scale. The result is that silly putty bounces off another lump of silly putty if thrown at it but sticks to another lump if left in contact for a second or two. Other similar properties are shown in the video.

| Notes |
Complex fluids are all around us and are very important in our technology. A number of world-class research programs in the MacDiarmid Institute involve complex fluids.
