Walking On Eggs - Sick Science!

The phrase "walking on eggshells" is an idiom that is often used to describe a situation in which people must tread lightly around a sensitive topic for fear of offending someone or creating a volatile situation. Literally walking on eggshells would require exceptional caution, incredible skill, and a sense of self-control that would be nothing short of amazing. But what if eggs were really much stronger than most of us imagine? What if nature's design of the incredible edible egg was so perfect that the thin, white outer coating of an egg was strong enough to withstand the weight of your body? Wake the kids! Phone the neighbors! It's time for the Walking on Eggshells challenge.


 

Eureka! Episode 14 - The Screw and The Wheel

This program provides examples and definitions of a screw and a wheel; a screw is simply a twisted inclined plane; a wheel is simply a circular lever, whose fulcrum has become an axle.

The Human Body is the Ultimate Physics Laboratory

The Tyndall Lecture by Dr Kevin McGuigan: 'The Human Body is the Ultimate Physics Laboratory' toured Ireland from 20 January - 12 February 2009.  We explore how the same physical principles determine the size of an aneurysm, the characteristic tone of flatulence or the curvature of a David Beckham free-kick.

Using the latest images, movies and demonstrations we see why perspiration is much more socially acceptable compared the cooling methods used by other animal species. A forensic examination of road traffic collisions and the injuries they produce reveal that the physical cause for these is often closely related to one of the roles played by saliva!

Hinged Stick and a Falling Ball

Two wood boards are connected by a hinge. A small cup is mounted near one end of the upper board with a tee for a ball on the end. The board is lifted to a certain height, and when released the ball ends up in the plastic cup. This shows that the board has moved farther than the ball in the same period of time.
