Bicycle Helmet With a Smell
Research scientists at the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany have developed a helmet that will make you think twice about continuing to cycle with a damaged helmet. For maximum protection, safety helmets need to be damage-free, but It is often impossible to know if a helmet is actually flawed after it has been dropped or hit by something. The researchers have used polymers that start to smell if there are any small cracks, and will really stink in the case of any large cracks.
