Note that the number in parentheses beside each fluid or each ball material is the specific gravity. The specific gravity is the ratio of the density of that material to the density of water. Hence, the specific gravity of water is 1. The specific gravity of olive oil being 0.92 means that olive oil has a density that is 92% of that of water. Aluminum, on the other hand, has a density of 2.7 times that of water.
Here are the values the simulation has for the viscosities - note how different they are. The units are pascal seconds (Pa s).
Olive oil: 0.08
And the mythical fluid “None” has a viscosity of zero and a density of zero. Just don’t tell Aristotle.
