The sticky nips we used in daily life are usually kinds of combination of plastic hooks and wool mat. The hooks will be able to catch on floss automatically when they are ranged on a semi-sticky film clip and affixed with brushes on the other side. Now, scientists have invented ”Velcro” – a kind of sticky nips based on the improvement of plastic products, which greatly augments the load-bearing and heat capacity of sticky nips. Amazingly, Velcro of one square meter size can hold up to 7 tons and withstand heat at about 800 degree Celsius.
