A Bit Difficult To See,

but all of the items pictures below have one thing in common, 

they all failed, from bicycles to electric face masks, all failures, so a good place to start if you are designing something new I would guess, and to see these epic fails there is a museum that houses them,

 located in Helsinborg, Sweden it is the Museum of Failure, the museum prides itself in providing a unique insight in to why products fail, I wish the museum every success, it would be a shame if it failed!
