And Now: AutoFrost Puts the Icing on the Cake

How’s this for a sweet new invention: five students from Franklin W. Olin College of Engineering have built a cake-decorating robot for a class project.

Called AutoFrost, the machine combines electronic sensors, computer programming, and precise mechanics with delicious gooey confections. Just doodle your design on a basic Microsoft Paint-like program, hit the button that says, “I’m ready to design an amazing cake,” and watch the frosting begin.

And Now: How to Melt a Rock Using Sunlight

Don’t try this at home, kids.

In this amazing clip, Jem Stansfield, the host of BBC’s Bang Goes the Theory (sort of a UK version of Mythbusters), visits the Solar Furnace Research Facility in Southern France. There a researcher demonstrates the power of intensely concentrated sunlight, using a special furnace that can reach temperatures of 3,500 degrees C (that’s about 6,332° F), and even melt solid rock!

The Physics of Football

NBC and the National Science Foundation have done it again. That’s right – the team that brought you the Science of the Olympic Winter Games has produced a new series of videos, and this time they’ll be “tackling” even more fun physics, math, and engineering concepts.

The Science of NFL Football, a new 10-part series, covers topics like vectors, projectiles, Newton’s Laws of Motion, and the Pythagorean Theorem. The production crew even went to some teams’ training camps, and filmed interviews with former and current NFL players and coaches. Our favorites after the jump.

Blast from the Past: A Vintage Engineering Video on Differential Gears

Ever wonder how cars can make turns without skidding? Well, you have engineers to thank – more specifically, those who invented the differential (a device which allows the wheels of a car to turn at different speeds).

This vintage engineering tutorial, made by the General Motors, clearly and engagingly explains how differential gears work. Posted on YouTube last year, it has now received close to a million views – not bad for something made in 1937!
