A recent spate of viral videos, the most recent of which showed a man filming himself in the act of putting a spinning tube inside a tube exchangers cylinder and spinning it in a spinning loop at the same time, has taken to social media to encourage viewers to try their hand at making one themselves.
The videos were uploaded to YouTube and Twitter in the weeks following a deadly cyclone hit southern Japan, killing at least 15 people and injuring hundreds more.
As of Thursday afternoon, the video was still showing up on YouTube and Twitpic, the platforms for sharing video on the internet.
The YouTube video is an excerpt of an earlier video posted on January 5, 2016, which featured a man in a similar position using a tube-shaped apparatus to put a spinning cycle in place inside a cyclone-shaped tube exchange, also known as a spiral tube.
In the first clip, the man, identified as Junichi Nakagawa, holds a cylindrical tube with a wheel in place and spins it inside a circular tube in the center.
The video shows a spinning centrifugal device being used to spin the tube inside the exchanger.
The device is spinning at about 2,000 revolutions per minute, which is about 1,000 times the speed of sound.
The second clip shows Nakagawas colleague, who was filmed on January 10, 2016.
In the clip, Nakagwa uses a spinning apparatus to get the tube out of the centrifugal machine, which he then uses to get it into a spinning circular tube, which then is spun in a circular loop.
After the tube is in place, the cylinder is spun and the cyclone cycle is set to spin for several minutes.
The two videos have been shared more than 50,000 time on the video sharing site.
The latest video appears to show a more advanced version of the same setup, which Nakagas colleague uses to create a spinning cylinder, which can then be used to create the cyclones spinning in the background.
Nakagawa told reporters he had not seen the video before.
He said he would not try it himself, and said he believed his colleague had made it himself.
