2006  Shear thickening:  "Walking on Water  "El Hormiguero (Spanish for "The Anthill") is a Spanish television program with a live audience focusing on comedy, science, and politics running since September 2006. It is hosted and produced by screenwriter Pablo Motos and airs on Cuatro, a Spanish television station. Recurring guests on the show include Luis Piedrahita, Raquel Martos, Flipy (the scientist), and puppet ants Trancas and Barrancas.. . .The show achieved some international attention in 2006 for having people walk across a swimming pool filled with a non-Newtonian fluid, an oobleck of cornstarch and water that was mixed in a cement truck. This experiment was performed in an October, 2006 episode of the show and was repeated with a new batch of oobleck on the Christmas Eve special episode due to its popularity." From en.wikipedia.org/wiki/El_Hormiguero, accessed 30Nov07


The first day of CM4650 Polymer Rheology class we watch this film:  Rheological Behavior of Fluids.  This film is one of 26+ films made by the National Committee for Fluid Mechanics Films.  Although made in the 1950s and 1960s, these films are still terrific at showing fluid behavior.

2007  The MIT National Committee for Fluid Mechanics Films (NCFMF) are now on the web!  They are available streaming and for purchase download.  The notes are there also in pdf form.

18 Feb 2009  Corn starch/water on an audio speaker.  There is a very interesting video at this link of oobleck dancing on an audio speaker:

Introduction to the study of fluid motion (1961, 25 minutes)  http://youtu.be/EIuU9Q8CGDk
The first in a widely used series of films on fluid mechanics, produced at IIHR under the direction of Hunter Rouse.
This introductory program, designed to orient engineering students, shows examples of flow phenomena from a host of everyday experiences. Empirical solutions by means of scale models are illustrated. The significance of the Euler, Froude, Reynolds, and Mach numbers as similitude parameters is illustrated.
Dr. Hunter Rouse served as Director of IIHR from 1944 to 1966. During this time, he was instrumental in strengthening IIHRs fundamental research emphasis and in developing teaching programs for hydraulic engineers. Through his writings, research, and global travels, he established IIHR as an internationally acclaimed innovative research and teaching laboratory.

Fundamental Principles of flow (23 min) http://youtu.be/2yojeSNzWiM
Second in the series, this video departs from the essential generality of the first by explicitly illustrating, through experi ment and animation, the basic concepts and physical relation ships that are involved in the analysis of fluid motion. The concepts of velocity, acceleration, circulation, and vorticity are introduced, and the use of integral equations of motion is demonstrated by a simple example.

Fluid Motion in a gravitational field (24 min) http://youtu.be/-xoyLhiEOus
In this third video of the series, which proceeds from the intro ductory and the basic material presented in the first two videos, emphasis is laid upon the action of gravity. Principles of wave propagation are illustrated, including aspects of gen eration, celerity, reflection, stability, and reduction to steadiness by relative motion. Simulation of comparable phenomena in the atmosphere and the ocean is considered.

Characteristics of laminar and turbulent flow (26 min) http://youtu.be/eIHVh3cIujU
The fourth video deals with the effect of viscosity. Dye, smoke, suspended particles, and hydrogen-bubbles are used to reveal the velocity field.
Various combinations of Couette and plane Poiseuille flow introduce the principles of lubrication. Axisymmetric Poiseuille flow and development of the flow around an elliptic cylinder are related to variation in the Reynolds number, and the growth of the boundary layer along a flat plate is shown.
Instability in boundary layers and pipe flow is shown to lead to turbulence. The eddy viscosity and apparent stress are intro duced by hotwire-anemometer indications. The processes of turbulence production, turbulent mixing, and turbulence decay are considered.

Form, drag, lift, and propulsion (24 min) http://youtu.be/4q5ffroIMMc
In the fifth video of the series, emphasis is laid upon the role of boundary-layer separation in modifying the flow pattern and producing longitudinal and lateral components of force on a moving body. Various conditions of separation and methods of separation control are first illustrated. Attention is then given to the distribution of pressure around typical body profiles and its relation to the resulting drag. The concept of circulation introduced in the second film is developed to explain the forces on rotating bodies and the forced vibration of cylin dri cal bodies. Structural failure of unstable sections is demonstrated.

Effects of fluid compressibility (17 min) http://youtu.be/SIehBPHL3cA
The last in the six-video series makes extensive use of the analogy between gravity and sound waves and illustrates, through laboratory demonstrations and animation, the con cepts of wave celerity, shock waves and surges, wave reflec tion and water hammer.
Two-dimensional waves are produced by flow past a point source at various speeds relative to the wave celerity to illus trate the effect of changing Mach number, and the principle is applied to flow at curved and abrupt wall deflections. Axisymmetric and three-dimensional wave patterns are then portrayed using color Schlieren pictures.
