USE TURBOMODE/TURBOWARP
This attempt at thermal energy is the best i got. IRL, when two molecules smack into each other, they bounce off each other at the same incident angle(assuming they have the same mass). It's like they teleport through each other to the other side(for frictionless places), which is what this simulation does. It also makes an interesting/realistic effect of when two molecules are at low relative speeds and touch, they stay together, I guess its like the creation of bonds?
