On the Mystery screen, the blocks have a customDensityProperty that can be used to directly set the density of the block. The range is currently 0-infinity, which exceeds what is pedagogically useful. Extreme densities can also create difficulties for the physics engine (e.g. very dense blocks are difficult to pick up off the ground).
@DianaTavares@jonathanolson and I discussed today, and decided that we should limit the density to something more realistic. A reasonable minimum would be the density of styrofoam, 150 kg/m^3. A reasonable maximum would be something similar to gold (the highest density listed in the table).
The densest naturally occurring element is osmium, with a density of 22590 kg/m^3. I tested in master with 10L block at 23000 kg/m^3 and the performance seemed reasonable. This slightly exceeds the density of gold, but I think it is pedagogically valuable.
For #150

@jonathanolson let's set the range to 150-23000 kg/m^3.
