Three Viscoelastic Effects
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)

| Now i know the thing i noticed playing with liquid soap is the Kaye Effect he | Ogaitnas900 |
| The second one looked like somebody blowing glass | ShastaPuppies |
| Some liquid fudge does the kaye effect. | Asdam12 |
| Viscoelastic fluids are a subclass of a so-called non-Newtonian fluids. | psidot |
| The liquid one uses has to be a so-called viscoelastic fluid. This means the fluid has both viscous and elastic properties and falls within the larger class of fluids known as non-Newtonian. A really viscous liquid alone (i.e. it is not elastic or "springy"), such as honey, will not exhibit any of the 3 effects shown as the behaviour of honey is essentially like that of water in that both are Newtonian fluids(i.e. the viscosity of the fluid does not change regardless of the force acting on it). | psidot |
| cool they kept getting more and more interesting | flamesmage |
| In europe, we just call it 'dreft' for doing the fucking dishes?? Now get started... | Brain0damaged |
| oooh, green spunk! | DJPaddy643 |
| beautiful | OurGreedIsOurDisasta |
| looks tasty | Spartan400 |
| it's almost alive :p | iceandsteele |
| ???? fuckin chet | patricotkd1 |
| douchebag | Sourpencil |
| cool! It's interesting to note that you pretty much see all of these effects in honey. | kitsune17717 |
| were u get that shit | timtima724 |
| As far as i know, starch + water makes a non-newtonian fluid. Ketchup is a thixotropic fluid, as well as toothpaste (u can squeeze it out on ur brush and it retains barrel-like shape), basically they keep their shape for some time. | anisakel |
| ok, what is the first one, is it just that it gets a larger stream when leaving the syringe? | jared1412 |
| Calm down. I just wanted to know if there was an actual product name for it, or he made it himself. | SatanOfTheAngels |
| it says at the begining, jesus christ theres always a dumb ass that asks 'ooo! whats he using in this experiment' when it clearly says in the videos...! | 03cammd79 |
| Anybody know what exactly he's using in this video? | SatanOfTheAngels |
| I'm no physicist, and I really wish to learn more about stuff like this, but does that make this a non-newtonian fluid? | SatanOfTheAngels |
| ... and since it is harder, the goo bounces off in the way that it does. But you will notice that the goo ends up resting (slowly) on another part of the goo pond and then very easily mixes in with the pond. I hope this makes sense. Basically this stuff could be liquid in a cup, but then if you threw it at someone or something it as if it were a stone (extreme example). | dootodoot |
| Hi all, I am not sure if anyone has explained it, but I will offer my explanation. This is demonstration of viscoelastic materials, whose elasticity (springiness) change when they are under a force of some kind. A non viscoelastic material would maintain the same elasticity when under any force (basically). So for example, in the last demonstration, the stream of goo entering the pond of goo is hitting the pond pretter fast and hard, causing that part of the pond to harden (less elastic)... | dootodoot |
| does any really viscous liquid do the same things? and is it surface tension or cohesion that causes the second effect | ANT31887 |
