A video of a small spider looking for a point above it tries to reach it, raises its front leg to feel the direction of the wind, and eventually weaves some of its threads to use it as an umbrella to climb.
Spiders fly without wings, some of which are replaced by strings to flow into the air. Scientists have long been unaware of how this might happen, but a researcher has now discovered more information about spiders' flight and flight pictures.
Korean researcher Monsoong Cho left one of his small spiders crawling over his hands. The spider quickly moved on a laptop keyboard and then climbed the edge of the screen upward. Eventually, the spider landed with a thread to the finger of Monsoong Cho.
It is said that spiders use this technique when they want to travel a long distance quickly, for example when they do not find food somewhere or when they are threatened to be devoured by their enemies, and this small insect can cut several kilometers at a height and a long distance in the air on the strings.
Since it is difficult for the human eye to see this web spider, humans have not yet learned much about sailing strings, which Monsong intends to change because it is possible for humans to learn much of this smart technology.
So the expert followed the spiders in a laboratory using a wind tunnel. For example, the machine looks like a giant hair dryer. The researcher controls the force of air from the machine and makes the spiders crawling over a stick in front of the tunnel and watching how the spider spins its thread and flies away.
In this way Monsong has already discovered how larger spiders need up to 60 spikes to rise in the air, while smaller spiders need fewer spikes.
