We show high-speed video of jets impacting a screen. While water flows through the open surface, non-Newtonian “yield-stress” fluids show distinct and interesting behavior, spreading on the surface as though it were solid if the yield stress is sufficiently high. These complex fluids can flow under high stresses to be extruded as a jet, yet still stick and accumulate on an open surface because they behave like solids under low stresses. This non-Newtonian behavior can be advantageous in several applications, including fire suppression, spray coating, and spray cooling. These videos highlight the interesting properties of this non-Newtonian yield-stress fluid, made from water and 0.1% or 1.0% by weight Carbopol microgel particles.
