Where can I get or how do i create a viscous fluid demo like in the beta promo?

I noticed in the blog promo there was this:

We’re also rolling out a new trigger module, which allows you to modify particle properties inside a list of colliders. In its simplest form you can destroy particles when they touch the colliders by using a custom scripting callback, and it’s possible to modify all particle properties. This can be seen in the viscous volume effect below.

I've looked at the particle emmitter and it all looks the same. Is there an example of how I can create a scene similar to the one in the beta promo vid?
