text: As the Weber number increases, the drop deformation upon impact also increases. The drop deformation pattern can be split up into regimes based on the Weber number.
  * At We << 1, there is not significant deformation.
  * For We on the order of 1, the drop experiences significant deformation, and flattens somewhat on the surface.
  * When We ~ 4, waves form on the drop.
  * When We ~ 18, satellite droplet(s) break off of the drop, which is now an elongated vertical column.
  * For large We (for which the magnitude depends on the specific surface structure), many satellite drops break off during spreading and/or retraction of the drop.
