Set Gravity to a low value (0.05) so the liquid is almost weightless.
Set the Steps per Frame parameter to 2.
Low values will give you a 'noisy' result which is ideal for explosions. High values (10 or more) tend to smooth out the movement of the liquid. A value of 2 gives a good result, so that's what is used in this tutorial. You can increase it if needed.
The Time Scale is set to 0.7 to slow things down a bit.
Set Surface Tension to 0.05 (as a comparison, the surface tension of water is 0.05 ~0.10).
Wetting is enabled, with the Consumed Liquid option set to 0.1, and the Drying Time to 0.01 seconds.
Wetmap particles are born on the surface of objects which come into contact with the liquid. A Wetmap particle group is created which can be used at render time to drive the options of a material using a Phoenix FD Particle Texture.
Wetmap particles also allow the liquid to stick to the surface of objects when Surface Tension and/or Viscosity is above 0.

From the Output rollout, enable Velocity under Output Grid Channels.
Velocity output is required for rendering with Motion Blur.
