Recently, it has been a high incidence! Someone was suddenly "slashed" while riding a bicycle? The "culprit" turned out to be a common spring activity...

In March, the spring breeze is like smoke, the temperature rises, and many people start outdoor activities. Flying kites is a common recreational activity during spring outings. Kites fly high in the sky with people's joy, but invisibly leave danger on the ground. The invisible kite line is like a sharp knife, and many people have been cut recently.

According to news reports, on March 22, people in Henan and Jiangsu had their necks cut by kite strings while riding bicycles. On March 23, a man in Sichuan was knocked down by a kite string while riding on a greenway, leaving a large cut on his helmet.

The above cases are shocking. How powerful is the kite string? Let's find out through experiments↓↓↓

The taut kite string is like an "invisible knife"

Most kite strings sold on the market are made of acrylic, polypropylene, nylon and other materials. The diameter of thin strings is only 0.2~0.5 mm, and the diameter of thick strings is 1~3 mm. They look thin and soft, but they have great tensile strength.

If a human body collides with a kite string in rapid motion, the string will become as sharp as a knife, which can cut the skin or even endanger life. In addition, kite strings are mostly white, gray, or translucent, and are almost invisible under light, making them more like invisible blades.

A set of experiments to intuitively feel the power of the kite line:

The bananas and cucumbers were cut in half the moment they crossed the kite string.
