Sequence of photographs of a tubeless siphon of a 1% aqueous PEO solution at a suction speed of 0.052cm/s. (a) The siphon is loaded with 4% by volume of 850 µm resin particles. All the mixture is cleaned from the beaker. (b) When there are no particles, a puddle of fluid is left in the beaker. The same container is used in case (a) and (b); the initial volume of the fluid-particle mixture in (a) is equal to the initial volume of the fluid in (b).
