The "impossible arrow" illusion by Prof. Kokichi Sugihara seems to break the laws of physics. The arrow always seems to point in one direction when you try to rotate it, but its reflection in a mirror points the other way! Learn about the illusion, how it works, and how to make your own 3D printed impossible arrow at Science Buddies: https://www.sciencebuddies.org/stem-activities/impossible-arrow-illusion?ytid=D54yMlIMN80&ytsrc=description Short version of the video:…
Did you know that a candle flame can jump through the air to light up another candle? It sounds like magic, but it is not! Watch this video and find out how the jumping flame trick works! This is our second entry in the @veritasium Science Communication Contest; it is inspired by the popular "jumping flame" experiment. It was made by Dr. Svenja Lohner, a Science Buddies' staff scientist.

World war 2 is fascinating in that its the first war, when time and time again, technological developments that occurred during the war were critical in determining the outcome of the war.
The first one of these was the german magnetic mine. To say that it rattled the british is kind of an understatement. Churchill said that it 'I fear it may encompass our ruin'.
The story of how it was beaten, in part by luck, and in part by skill, is one of the early and frequently untold stories of…
Have you ever seen a video where it looked like a car's wheels or a helicopter's blades were spinning backwards? This optical illusion is called the wagon wheel effect, named after old movies where it looked like wagon wheels were spinning backwards. This video explains what the wagon wheel effect is and how you can film it yourself at home with a fan or a drill. Written instructions for this fun STEM activity are available on the Science Buddies website:…
