Thanks to these factors, Youtube, which was founded in 2005, now has a billion users. As Youtube grew, some netizens constantly contrib\-uted to its contents. These people are called youtubers (Youtube+er), and the Pharos would like to introduce you to three youtubers who upload videos that give you knowledge and information.

The Backyard Scientist is a channel that experiments with things that its viewers wonder about, and explains the results with scientific theories.

Other content creaters who experiment do it to prove a scientific fact, but the backyard scientist does it simply to see what happens. His videos are very interesting because he uses excellent equipment like high speed cameras and thermographic cameras, and the experiments generate a lot of smoke and explosions. The explanations about the results are also very well explained. The backyard scientist began experimenting long before his Youtube career started and has had many injuries.
