What is dust? And where does it all come from?
Everything in our homes gathers dust. But what exactly is it? Where does it come from, and why does it keep coming back? Is it from outside? Is it fibres from our clothes and cells from our skin?
Yes, but it’s a lot more than that.
People from all around Australia have been sending their dust to Macquarie University’s program. Instead of emptying the vacuum cleaner into the bin, they package it up and we analyse it. As a result, we are getting to know the secrets of your dust! In total, 35 countries are part of this program.
