You Should Be Using Safari’s Hidden Picture-in-Picture Feature

PiP makes it easier to multitask on your Mac.

Multitasking is essential when using your computer, which is why there are so many productivity features built into your Mac. Hot corners make it easy to quickly run system actions with your mouse, while keyboard shortcuts do the same, but with your keyboard, of course.

There are always new productivity features to discover on MacOS — and there’s one in Safari you should know about.

Picture-in-Picture mode allows you to shrink any video you’re watching in Safari, whether it’s on YouTube or Twitch, and create a floating window you can move around your screen. That way, you can visit other websites and use other applications, while you continue to watch.

There are several ways to enable PiP, which I’ll show you below.

PiP is one of the more underrated features on the Mac. Want to learn more about others? Check out these Command keyboard shortcuts on MacOS and the hidden Hello screensaver. You should also read about 10 Mac tips and tricks you probably didn’t know about.

Safari’s PiP button is hidden in the address bar

If a video is playing in Safari, go to the address bar at the top of the window, right-click the blue audio button on the right of the website address and click Enter Picture in Picture. The video will then automatically move to a floating window.

Enter Picture in Picture Setting in Safari — You can also mute the tab and configure auto-play settings from here.

The floating window playing the video will appear above all other open applications, including Safari, and will snap into any of the four corners of your desktop. You can adjust the size by hovering the mouse over the window’s borders and corners and then clicking and dragging to make it bigger or smaller.

The window also has two buttons: One to pause/play the video and the other to snap the floating window back into the web browser. You can also just close the floating window with the X button on the top left.

There are two other ways to enable Picture in Picture on MacOS

If you don’t see the blue audio button in the address bar or have multiple videos playing in Safari, there are two other ways to use Picture in Picture.

The first is by clicking the PiP button in the video’s playback controls. Not every video player will have the PiP button, so you’re limited in use. The PiP button appears as two rectangles with an arrow pointing from one to the other, but you can also just hover your mouse over the various buttons to find the Open Picture in Picture mode option.

PiP button in YouTube — You’ll find Picture in Picture between the AirPlay and Full Screen buttons on YouTube.

If you don’t see a PiP button, you can right-click the video and see if you get an Enter Picture in Picture option. On YouTube, you have to right-click twice to get the correct menu, but you may only need to right-click once on other websites to find the PiP setting.

Right-click menu in YouTube that has Picture in Picture mode — You can also use this menu to enter full screen and show the video player’s controls.

Yes, This Swimming RoboTurtle Is Adorable. It Also Has an Important Environmental Mission

Beatbot is best known for making pool-cleaning robots, but it was its swimming robot turtle that won our hearts at CES 2026.

Few things in life have made me feel more privileged and awestruck than the opportunity to swim with sea turtles in their natural environment. The way in which these gentle creatures navigate through their underwater world with their deliberate and careful fin strokes is utterly mesmerizing to watch.

It’s a distinctive style of movement — so much so that when I saw Beatbot’s RoboTurtle swim across a water tank on the show floor at CES 2026, I knew that this wasn’t simply just a pool cleaner robot with turtle features tacked on. This was a studied example of biomimicry in action.

The reason for this is that the company’s engineers went on a two-month expedition to study sea turtles in their natural environment, Beatbot’s Eduardo Campo told me as we watched Turtini (the team’s affectionate nickname for RoboTurtle) splash around in its pool. «We did a lot of motion capture, like the things they use in movies, because we need to develop those joints that it has,» he said.

This isn’t RoboTurtle’s first time at CES — it also appeared in 2025 as a static concept. This is the year, however, it’s found its fins, so to speak. Not only can it swim, but it can also respond to hand gestures: I throw it an OK gesture, and it dances in response. But as cute and limber as it is, RoboTurtle is a robot with an important mission.

RoboTurtle is an environmental research tool, built with input from researchers and NGOs, which can go where humans or other machines cannot for fear of disturbing complex and delicate underwater ecosystems, particularly coral reefs. It can move silently and naturally in a way that won’t scare wildlife, monitoring water quality and fish numbers with its built-in camera.

«One of the groups that we’re working with, they want to study the coral reefs in near Indonesia,» said Campo. «There was a very big incident over there with a boat that came up onto a coral reef and it disrupted the environment, [so] they want the least intrusive robot possible.»

The group wants to deploy RoboTurtle for certain periods every year to monitor the recovery of the coral and monitor the fish population, he added. Beatbot is currently training the built-in AI to give RoboTurtle monitoring and recognition skills.

At CES, I watched RoboTurtle paddle about only on the surface of the pool, but it can also dive down up to five meters. However, it needs to resurface to send data and its GPS signal back to base, much like a real turtle that needs to come to the surface to breathe. This also gives it a chance to recharge via the solar panel on its back.

Even though I was impressed with RoboTurtle’s swimming ability, Campo estimates that the Beatbot team is still a year and a half away from perfecting its technique, with the robot ready for full deployment in between three to five years.

CES 2026 is a show where tech with a real purpose feels scarce, so it sure is refreshing to see a company use its expertise to build something designed with a sustainable future in mind. It might be a while until we see RoboTurtle take to the seas, but I’m glad that I got to witness it at this stage of its journey.

These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.
