Syrris Orb Pilot - Draining (with baffles, 150 RPM)
A video showing how baffles affect the draining of a 20 L Syrris Orb Pilot vessel. The draining vortex forms only as the reaction mixture nears the end of the glass baffles. The start of the video is sped up, then resumes normal speed (plus a short section of slow motion).
