Question: what happens if you bring a vacum cleaner into space and turn it on

That’s such a cool question! You might have some fun if you turned a vacuum on in space; because there’s no gravity to hold the vacuum to the floor, the spinning fan would spin the vacuum and spin you too! This wouldn’t last very long though as the vacuum would not be able to suck in cold air to keep it’s parts cool and will overheat. So if you want to clean the moon you might want to bring a brush and dustpan instead 🙂
