Ở Vũ Hán thì sợ rồi

các nhà khoa học ở đại học khcn vũ hán, china phát minh ra toilet siêu trơn trượt...
Scientists at Huazhong University of Science and Technology in Wuhan, China, have created a new type of ultra-slippery (siêu trơn) toilet bowl, making it impossible for anything to stick to it. The new toilet bowl design could eventually (cuối cùng) replace porcelain (sứ) and ceramic (gốm) toilet bowls if they scaled it up.

Humans have relied on porcelain and ceramic for their toilet bowls for centuries. While it seems unlikely we’ll see that material replaced completely anytime soon, if this ultra-slippery toilet bowl that scientists have made takes off, it could give us a new material to rely on.

The ultra-slippering toilet bowl was designed to be a 3D-printed item, and as a video featured by New Scientist shows, almost nothing can stick to the bowl. Even more intriguing (thú vị), the researchers found that the toilet bowl remained slippery, even after being used multiple times and rubbed down with sandpaper (giấy nhám).

One of the biggest advantages to having an ultra-slipper toilet bowl isn’t just its cleanliness. If nothing sticks to the bowl, then that means we could also see reduced water usage for flushing the toilet when using this type of material.

The researchers call it an abrasion-resistant super-slippery flush toilet (ARSFT), and it is made using materials that easily repel complex fluids and viscoelastic (nhớt đàn hồi) solids
