We've got 19 billion of them in our bodies.

Here's an individual hair with a little split end there.

The smallest blood vessels are called capillaries we've got 19 billion of them in our bodies.

And then she did something magical for the first time ever, she measured the force of a single gecko hair that allowed her to discover a completely new way to stick to something, something no human has ever known before.

They have hairy little toes, huge numbers of hairs, and each hair has the worst case of split ends possible, 100 to 1,000 nano tips that an animal has on one hair, and 2 billion total, and they don't stick by glue, or by suction, or by velcro.

The distal's a little bit different so let's say this is a cell, and let's say that this is a peritubular capillary right here.

We were fortunate to work with another group at Stanford that built us a special manned sensor, that we were able to measure the force of an individual hair.

In fact, there's the diameter of your hair a gecko has two million of these, and each hair has 100 to 1,000 split ends.

And if you blow that up, and zoom in 900 times, you see there are hairs there, tiny hairs. And if you look carefully, those tiny hairs have striations. And if you zoom in on those 30,000 times, you'll see each hair has split ends.

The smallest branch of the hairs looks like spatulae, and an animal like that has one billion of these nano size split ends, to get very close to the surface. In fact, there's the diameter of your hair a gecko has two million of these, and each hair has 100 to 1,000 split ends.
