mind blowing!

this is great!
i love how you put "the smallest sized particle a surgical mask blocks out"
right next to "the largest virus", and the virus is still smaller
but some things feel off, like how a hummingbird egg is roughly the same size as a coffee bean? is it really that small?
and the saguaro cactus is huge in relation to the person and plane..
