And you thought that the velcro on your jacket was impressive. These Velcro fasteners were made by German engineers and can withstand 35 tons of force. Needless to say, these aren’t for your clothes. One side has spikes and the other has steel brushes, so it’s just like real velcro. It can also withstand heat of up to 800 degrees Celsius.

And if you tear these Velcro strips vertically, where it’s stronger, it can hold up to 7 tons. We aren’t sure how much of this stuff it actually takes to support that much weight, but it’s pretty amazing anyway. Especially when you consider that just like everyday Velcro, it can be opened up without specialized tools and used again.
