Hi Benjamin, Sorry no links but thanks for making me aware of this - I had never heard of electrorheological liquids, so read about them on the internet. Very interesting stuff. Rod

Interesting technology. I had to google it also. Good luck in finding a source for small quantities.

yeah pretty neat stuff, gonna be expensive to test my theory though. I did find one place where one could order a liter of the stuff for like 800 US, but I don't need that much. I think they might have…

Apparently you can make your own, with equal parts of corn starch and vegetable oil. https://www.youtube.com/watch?v=esSs6_cEKtM

Sounds like fun!

that would be oobleck, what I am needing is a liquid that changes viscosity when in the presence of an electrical field, the actual name for it is electrorheological fluid, whereas oobleck is just considered a smart fluid due to it changing viscosity based on stress. there is also magnetorheological fluid and i'll let you guess what makes that one change viscosity
