Your body contains trillions of cells...
A cell is the basic building block of life - we are all made of cells, but I had NO IDEA it was that many... By the time you're fully grown, your body may contain 28-36 trillion cells.
Cells are specialised to do all the different things a body needs to do - making our muscles and bones to move, layering themselves into the surfaces of our skin, carrying gases through our veins, even making up the veins themselves. Lots of cells, busy keeping us alive.
And our bodies contain TRILLIONS of them.

I'm Eliza, and I'm a scientist and illustrator who loves making the invisible, completely mad bits of science feel like an adventure, especially for kids who feel like science isn't for them.
In a world full of 'Did you know?', 'Fun Facts' and a surge of AI hallucinations, join me on my journey of finding out all sorts of ideas that I DIDN'T know, despite having a PhD in science, so we can imagine what each idea might be like, together.
