Welcome back to Trivia Waves, where we broadcast the most jaw-dropping facts to ignite your curiosity! Today, we’re floating into the sky with a science tidbit that’ll blow your mind: did you know a cloud once weighed more than a million pounds? Tune in as we uncover the surprising weight of something that looks so light and fluffy.

Clouds might seem weightless as they drift across the sky, but they’re actually made of tiny water droplets or ice crystals—trillions of them. Scientists estimate that an average cumulus cloud (the puffy white ones you see on a sunny day) spans about a cubic kilometer and contains around 0.5 grams of water per cubic meter. When you do the math, that adds up to roughly 1.1 million pounds of water! That’s the weight of about 100 elephants, all floating above your head.

This mind-boggling fact was calculated by the U.S. Geological Survey to help people understand the water cycle. Even more incredible? When those clouds turn into rain, all that weight comes crashing down—yet the cloud stays aloft thanks to updrafts and the tiny size of the droplets. It’s a perfect reminder of how nature can defy our expectations, and we’re loving every second of it here at Trivia Waves.
