No, it's not flubber from the movie with robin Williams, a greatly unappreciated scientific masterpiece.

This slime is truly a groundbreaking discovery and creation that could change the future of robotics, medicine, and humanity.

Yes, the future of humanity may be impacted by a magnetic turd.

Okay, in all seriousness, what exactly is it?

And why is it significant?

Well, we use robots for all sorts of purposes but they aren't exactly known for their dexterity and nuanced touch,

which is why this robot simply learning how to peel a banana without smashing it to bits was a huge breakthrough just this year.

Miniature robots have also been created to navigate tight spaces, like these tiny objects coded with a magnetic spray,

making the delivery of pills to a very specific part of the body a possibility.

And the rise of nanobots has even opened the potential for microscopic machines that could be deployed inside the human body and act to identify or even destroy cancer in the future.

But robots combining the ability for tight or tiny navigation and physical manipulation together are super rare.

On the one hand, you have elastomer-based soft body robots that are great for gentle manipulation in sensitive environments but are limited in their deform ability or how small they can get.

And on the other hand, you have fluid-based soft body robots which are really good at fitting into small spaces but are limited by their unstable shape.

This is where our slime robot comes in.

The slime is made up of a polymer called polyvinyl alcohol and borax, which can actually be created fairly simply.

What you end up with is a slimy blobby-like substance that can act like both a liquid and a solid.

This behavior is called visco elasticity and it's kind of like when you mix together water and cornstarch and make oobleck, the non-newtonian substance whose viscosity changes under pressure.

If you smack it or touch it really quickly, it acts like a solid, but if handled slowly and gently, it acts like a liquid.

The same is true of this slime, but what gives it its unique ability to move are tiny particles of neodymium magnets.

Neodymium can create powerful permanent magnets that are super useful when you need a low magnet mass or volume.

And in this case, because the slime is so small, the researchers wanted to use tiny magnets with high power.

And these magnetic particles within the slime can be manipulated in order to make it travel, rotate, or form different shapes.

I'm quite interesting using the magnetic field to drive, you know, this kind of tiny device inside the body.

The main advantage is that the magnetic field is not that harmful to the tissue, to the body.

Okay, so we've got a magnetic slime robot on our hands.

But what exactly is it for?

Like, what can it actually do?

Right now, the biggest focus by its creators seems to be in the medical field, though it's certainly not limited to just that.

Because of the slimes ability to navigate tiny spaces and be manipulated, it could be useful in the digestive system.

For example, if you or a child swallowed something toxic, like a small battery,

the slime could be deployed to wrap around a toxic object and help prevent toxic electrolytes from leaking out.

Much like other miniature soft body robots, it could be used to assist minimally invasive surgery or even targeted drug delivery.

The slime is able to navigate channels as small as 1.5 millimeters, which is tiny, like this tiny, so small.

They are proven to work on multiple surfaces and substrates in complex environments, from plastic to glass, silicone, water, metal and paper.

Ultimately, the slime is extremely versatile, which is rare for conventional liquid based robots.

It can stretch up to seven times its original length.

And unlike other soft body robots, this slime doesn't require a pre designed shape and can be reconfigured in situ.

The magnetic slime can grasp multiple target objects simultaneously and even extend tentacles in three directions.

I consider it more like a surgical tool because it's larger and you can apply a much stronger force on the object,

because you can put more magnetic material inside of the slime in comparison with those nanobots.

The truth be told, the functional use is still really hypothetical and in its fundamental research stage where scientists are just trying to understand its material properties.

It could be used as an electrical conductor to connect electrodes and hard to reach places or in motion sensing of the human body for wearable devices.

Electronic devices often fail because of partial disconnection, whether from environmental factors or scratches by sharp objects.

And this slime could help prepare those.

The slime is even self-healing, bringing itself back together after being chopped apart.

This is because of the hydrogen bonds between the bori ions and OH groups,

which can occur spontaneously without the help of external sources, and after healing it maintains its physical integrity and electrical capabilities.

The researchers even did a series of tests with LED light bulbs, showing the slime self-healing between a circuit and the lights coming back to full strength.

The true possibilities are just beginning to be explored as it's essentially a new type of material, and that will likely be the focus of future experiments with the slime.

Of course it's important to remember that the slime does not have any form of sentience or autonomy as it's completely controlled by human manipulation, at least for now.

And in its current state, the magnetic particles themselves are actually toxic, but protective layers of silica have been tested for hypothetical use in humans to keep it safe.

In the future, we hope that we can realize some kind of autonomous control and also the device can have some intelligence.

Basically, a slime robot should know how to deform, how to behave, how to manipulate, or interact with environment.

So, really, I mean we have two parts.

One is from the engineering point of view, the other is its application for medicine.

At the end of the day, it's another really creative and cool step in robot creation and manipulation that will likely bear even more fruit for future research and more creations.

Speaking of creations and creativity, I want to thank today's sponsor Skillshare, who's giving 30% off a yearlong skill share membership for anyone who clicks are link in the description or uses our code, ASAPSCIENCE30.

You want to improve your skills? Skillshare gotcha.

You want to develop new ones? Skillshare got you covered there too.

You all know how much we love using Skillshare here at ASAP Science, and I know you will too.

Of course, I recently learned so much from this called Find Your Style. Five exercises to unlock your creative identity by AndyJ. Pizza. Yes, Pizza.

The course helps you find your personal artistic identity through exploration, whether it's art, podcasting, speaking, or any place where you want to develop a strong sense of self and point of view.

How do you know your own taste? What makes something good?

These are questions that I often ask myself and even struggle with.

So it's nice to hear them processed out loud and have the ability to work through them.

It's just one of the thousands of inspiring classes you can take to invest in your personal growth, whether you're wanting to make a career pivot or just expand already existing resources from technical classes on photography and animation to personal and spiritual growth to plant care, Skillshare has it all.

Even though science can often feel very straight-lined or like a narrow way of thinking, it's been shown time and time again that some of the best and most celebrated scientists are people who expanded their horizons and other creative interests beyond science.

So, I highly recommend you to try that out yourself too.
