Your toilet flush might be spraying invisible particles into the air. In one experiment, engineers used lasers to capture what happens when a toilet flushes. They discovered that the flush creates a powerful jet of air traveling faster than 2 meters per second, launching tiny droplets nearly 5 feet into the air in just 8 seconds. Even more disturbing? A minute after flushing, tiny particles were still lingering in the air above the toilet. So, the next time you flush, remember: what you can't see might not stay where you think it does. #research #Science #technology ##Environment #sciencefacts
