Props to the brains behind the velcro, but here’s something from the future – Metaklett, a stell version of velcro that looks a whole lot scarier as well. On one side are sharp spikes, while the other end has jagged steel brushes. The Metaklett is surprisingly powerful, where a square meter of that stuff is able to carry up to 35 metric tons and can withstand heat of up to 800 degrees Celsius without missing a beat. Would be interesting to see how Metaklett is applied in everyday lives, we’re guessing heavy duty industries will definitely find a good and practical use for this, while the rest of us cower and shiver in fear whenever we see those spikes jutting out.
