Video of the week – Prince Rupert’s Drops

By / December 18, 2008

Again, we  present another beloved classroom demonstration in materials science. This one is a non-intuitive display of surface tension, residual stress, interior tension, potential energy and tempered glass. To create a Prince Rupert drop, molten glass is dropped into cold water. The glass rapidly forms into teardrop shape with a extended, fine tail. The material…

Video of the week – Oodles of Oobleck

By / December 3, 2008

Today we feature a classic experiment/weird experience in materials science, rheology, shear stress, strain rate, non-Newtonian fluid mechanics – and gooey fun: the Oobleck Run, AKA (with a great deal of hyperbole) Walking on Water. This video was prepared for the Discovery Channel’s great new series, Time Warp. The science behind this has significant implications,…

Helping ‘off-the-grid’ people see the light

By / October 30, 2008

A fascinating story is unfolding in Mbita, Kenya, where OSRAM – one of the world’s two leading lighting firms – is embarking on a program to improve the environment and the lives of more than 175,000 Kenya fishermen who live “off-the-grid,” in a remote area of the world with no access to electricity. These fishermen are…

Video of the week: ICE-T program at Hocking College (Ohio)

By / October 15, 2008

This is a good example of a student-made film about a materials program. This one is about the Industrial Ceramics Engineering Technology program at the college located in southern Ohio. They review slip development, glazing, heat treatment and burners, strength testing and microscopy. According to the students, ICE-T is hot!
