So, this past Friday night, Viv and I thought we'd give it a try.
For those of you that don't know. A non-newtonian fluid is a fluid whose viscosity is not a single constant value, meaning that the relation between sheer stress and strain rate in non-linear.
Basically, in regards to our activity, our fluid acted like a solid when struck or abrupt force was applied. When left alone or little force was given it acted as a liquid. Check out this wiki entry if you're interested in more information.
Just in case any parents are interested in trying this, just know this:
- it's definitely a fun and easy activity to do at home,
- It's non-toxic,
- can be very messy, and
- skip the food coloring. Viv and Pxian's hands will be green for the next week.
The recipe we used was from this blog.
Here's the video from our experience.
