A team of students from the Harbin Engineering University have created a small paper bridge able to sustain more than 25 times its own weight.

The young undergraduates spent an entire month designing and building the bridge, and finally presented it to the world,on November 7. Now, building a paper bridge model doesn’t sound that remarkable, especially when the builders are attending an engineering institute, but their creation is much more than a simple paper model. The 3.8-meter-long, 1.2 meter-tall bridge weighs just 58 kilograms, but it is able to sustain up to 1,500 kilograms, and the group of 11 students proved it by standing on the bridge at the same time.
