RapidFIRE: Supersonic car takes shot at speed barrier

August 6, 2013 4:19 pm | by Eric Sorensen, Coordinator of Multimedia Development Videos Comments

The Bloodhound supersonic car is going to take a shot at going supersonic in the summer of 2015, and it is relying on rapid manufacturing to speed past the 1,000 mph speed barrier. The tip is subject to forces as high as 4,915 lbs/ft2. To cope with such loadings, a prototype tip has been designed in titanium and will be bonded to Bloodhound's carbon fiber monocoque body.

DIY Hacks & How Tos: Developing fingerprints with Superglue

August 6, 2013 9:53 am Videos Comments

Fingerprinting is an important element of crime scene investigation. You may have heard that Superglue (cyanoacrylate) can be used to develop fingerprints. But you might not be aware that this technique can easily be performed at home with everyday materials. So in this project, I am going to teach you how to develop fingerprints with the Super Glue fuming method.
