It's often been said no idea is too small. Well, except maybe this one.
A Russian man named Nikolai Aldunin makes sculptures. But these aren't your typical sculptures.
They're microscopic... as in, they're so small you need a microscope to see them. And Nikolai has one from 1985.
He uses everything from toothpicks to syringes to superglue to make the sculptures.
But perhaps even more amazing - he says he works between the beats of his heart in order to keep his hands still.
Try that sometime.
The secret, as Nikolai explained to TIME magazine, is this: "You musn't get into a state of worry. Everything that you feel in your soul is transmitted to your hands."
Here's some of his work.
7 camels and 3 palm trees inside the eye of a needle.
A gold AK-47 on a matchstick. It has 34 individual parts.
A likeness of the novelist Leo Tolstoy on a grain of rice.
A bike on a needle.
A tank on the open face of a sliced apple seed.
