InformationVideo published by PetTheDamnDog This video shows a strange support effect that seems to defy gravity. Yet the small sticks supporting the weight are arranged to form a kind of hook that grips the table and uses gravity to stay suspended.

InformationVideo published by Physics4Life In this video by Physics4life, meaning physics for life, an experiment shows that a small glass of colored water can break a glass jar if it is connected by a sufficiently thin tube to the roof of the high school where the demonstration takes place. In short, the higher it is, the more pressure there is,...

InformationVideo published by 24gatti In this very short 23-second video, you can see the shock wave in a tunnel bounce several times.

Since their first detection by the James Webb Space Telescope, researchers worldwide have been puzzling over the nature of curious stellar objects nicknamed the "little red dots". Compact, intensely red, and unexpectedly luminous for their era in the history of the universe, these mysterious objects have fueled debates and hypotheses for several...

InformationVideo published by Things made of cardboard This strange sculpture, made of cardboard and strings, is based on the principle of tensegrity. It requires a good distribution of weights and string distances, so that the central string supports all the weight, while the two fasteners on the left of this video block the rotation effect of...

InformationVideo published by Physics Girl In this Physics Girl video, Dianna Cowern explains the scientific phenomenon that shows why, under certain conditions, it is possible not to get burned. The principle is the same as when you put water on a really, really hot pan. If the temperature is high enough, the water no longer touches the surface...
