Cardboard bike helmet could revolutionize head safety
|
|
|
As highlighted by the cardboard bicycle, cardboard can be a surprisingly versatile manufacturing material in the right hands.
|
Further proof of this comes via the Kranium: a bicycle helmet constructed from cardboard and designed by Royal College of Art student Anirudha Surabhi, which promises to be 15 percent lighter than standard helmets, while absorbing up to three times the impact energy during a collision.
Results showed that Kranium can be fallen continuously up to 5 times but it is not broken instead of “ cooker” used to be damaged
This kind of helmet recently sold in some websites: (http://goo.gl/rMxRB) with price of 129 USD( about 2.7 million dong)
You can watch video on website http://goo.gl/6YBPL to fell what special helmet is Kranium
