How to Do an experiment showing three viscoelastic effects

Check out how you can create three viscolastic effects with this how to video. A dyed polyvinyl solution crossed linked with sodium tetraborate in solution is found to exhibit the following three different viscoelatic effects:

1. The Barus Effect (extrudate swell)

2. The Weissenberg Effect (rod-climbing)

3. The Kaye Effect (liquid leaping lanyards)

These are great experiments to do with your kids. Watch this how to video and you can demonstrate three viscoelastic effects at home.
