The base of this pattern is a traditional reverse cascade, (siteswap 3 in siteswap notation), with an extra "mess" added by crossing and uncrossing arms.
Cascade impactor Cascade impactor A cascade impactor measures the reach range of a particulate substance as it moves through an opening with the use of aerosol. Cascade impactors are strictly measurement-related devices. In addition to measuring the range of substances moved through an opening by aerosol, the impactor can also be used to determine the particle size of the distributed substance. A cascade impactor collects its samples in a graduated manner. This allows the user to identify the sizes of the substance particles as the particles are distributed from the propellant aerosol source.When the aerosol substance is distributed into the cascade impactor,
