Particles Floating down a pipe

[cubtronic]

Hi there.

I've like to recreate the following animation showing particles 'floating' down a pipe. Similar to this ( jump to 1:20 ):- 

I have a copy of the Newton plugin and have re-created the assets, but what kinematic values do I need to apply to the scene and the particles? Currently I can only get them to drop and roll down the pipe, but I need them to float and bounce off the walls, yet still follow the path downwards.  Or can anyone else offer an alternative method?

I'm not a Newton user myself - so I'm not sure if this is possible in Newton, others will have to advise on that. However, I think you might be able to get close to this using the native 'foam' effect with a flow map. That effect does take some setup, so you'd certainly need to read the help info:
