Residents were left completely confused after hundreds of tiny blue balls suddenly appeared falling from the sky in the Pittsburgh area.
The mysterious objects were perfectly round, about the size of grains of salt, slightly blue and transparent. Even stranger — they didn’t melt, didn’t break apart, and when squeezed open, they contained liquid inside.
At first, many people thought the strange beads looked exactly like the filling found inside silicone desiccant packs, while others feared it could be some kind of chemical substance or environmental hazard.
Photos of the bizarre discovery quickly spread online as users tried to figure out what was really happening.
But the truth turned out to be far less dangerous — and surprisingly ordinary.
After a flood of guesses and theories, the mystery was finally solved. The tiny blue balls were identified as survey markers used as fixed reference points for mapping and trekking.
These small markers are apparently scattered in many areas and often go unnoticed unless someone suddenly spots a large number of them at once.
Now people online say they can’t stop noticing them everywhere after learning what they actually are.
