Your house is full of dust because tiny particles are constantly floating around and finding their way into your home.
How Dust Gets In
How Dust Stays In
Now imagine you're inside a room with lots of corners and cracks. The dust floats in the air like little clouds, and when they find a spot to rest, like on your bookshelf or under your bed, they stay there. It's like when you drop a crumb on the floor; ants come crawling out to eat it.
Why You Can’t See Dust
Dust is so tiny that it’s like a group of little invisibility cloaks wearing sunglasses. They’re too small for you to see clearly, but when you shine a light or wipe your table, poof!, the dust becomes visible again, just like magic, but not really.
So next time you see a cloud of dust, remember: it's just a bunch of little travelers having a party on your floor.
Examples
- Your cat shedding hair mixes with the dust from your dryers.
