The Surprising Genius of Sewing Machines

- Can you explain how
a sewing machine works?

There&amp;#39;s that little
needle that&amp;#39;s moving up

Because the needle is
never actually going fully

So in order to invent the
sewing machine, we first had

It&amp;#39;s one of these things that
almost no one thinks about,

Every piece of clothing you&amp;#39;ve ever put

on virtually was made by a sewing machine.

So in this video, I&amp;#39;m going to explain

And I promise when you
find out, you will find it

at the end of the show.

- The foot pedal is right
in front of your right foot.

You can gently rest it. It
doesn&amp;#39;t need a lot of pressure.

So easy does it, and you
should be able to start going.

of fabric together, this
is how I would do it.

and there are more sophisticated
stitches you could do.

But if you&amp;#39;re trying to mechanize
any hand stitch, you run

through the fabric, you have
to release it on one side

This is almost impossible
for a machine to do,

So in order to invent the
sewing machine, we first needed

to come up with a totally
new way of sewing.

In 2016, researchers found a
needle in a cave in Siberia

that dates back to about 50,000 years ago.

that homo sapiens didn&amp;#39;t
live in that cave.

It was inhabited by the
Denisovans, a now extinct species

So sewing isn&amp;#39;t just a homo sapien thing,

But in other regards, it
looks like any modern needle,

and an eye on the other
end for the thread.

Needles have remained basically unchanged

Artifacts from caves in
France, ancient Egypt, Greece,

India, China, and Japan,
all look about the same.

We&amp;#39;re not exactly sure what motivated him,

some believe he was trying
to invent a sewing machine,

of flipping the needle
over twice every stitch.

But what he created was
a needle that was sharp

on both sides, so you
could pass the needle back

and forth through the fabric
without flipping it over.

He patented his invention, a
needle for ornamenting fabrics,

But the two-sided needle
delivered an unexpected benefit

used by all sewing
machines up until this day.

It moved the eye of the
needle next to the sharp tip.

into the fabric, the thread
does go below the fabric,

but when I pull it out, the
thread also gets pulled out.

So it seems like we&amp;#39;ve achieved nothing.

We need to find a way to tangle the thread

when it&amp;#39;s at the bottom of the stitch

And luckily, there are
two ways of doing this.

If you can keep a loop of
thread underneath the fabric,

as I pull the needle out, well
then, I can move the fabric
