A video shows a device automatically sorting hundreds of small balls by color.
In January 2018, the Anonymous Facebook page shared a video that seemingly showed a simple machine automatically sorting hundreds of small balls by color along with a request for someone to explain how the device worked:
Some viewers theorized that the video (which can be viewed in full below) was actually upside down and and showed colored balls in separate containers falling and mixing together through the machine. Others suggested that the device actually sorted the balls by size, not color.
The truth, however, is that this machine doesn’t exist. The viral video is a computer simulation that was originally posted to Reddit by “the_humeister.” The Redditor explained that he created this simulation of a “Galton board” (a device used to demonstrate a mathematical theorem) with Blender, an open-source 3D computer graphics software.
They originally ran the simulation with all white balls. When the objects all settled, they assigned each ball a color and ran the program again. Or as the_humesiter explained:
Run the simulation. Color the balls afterwards. Render from the beginning.
Here’s the original video of the “somewhat flawed Galton Box”:
A similar video has also made the social media rounds:

Most Snopes assignments begin when readers ask us, “Is this true?” Those tips launch our fact-checkers on sprints across a vast range of political, scientific, legal, historical, and visual information. We investigate as thoroughly and quickly as possible and relay what we learn. Then another question arrives, and the race starts again.
We do this work every day at no cost to you, but it is far from free to produce, and we cannot afford to slow down. To ensure Snopes endures — and grows to serve more readers — we need a different kind of tip: We need your financial support.
Support Snopes so we continue to pursue the facts — for you and anyone searching for answers.
