[Mark Rober speaking]
We're about to test the accuracy of this plane I built with Bard, and then we're gonna send it
through that ring of fire. [upbeat music begins] When Google asked me to try out the latest version of Bard, [upbeat music fades out]
I had an idea. I wanted to know if the advanced reasoning and multi-modal capabilities
in the latest version of Bard could master a very specific brand
[people shouting] of slightly chaotic, educational
science content. [toy gun firing] In short, could Bard create
a better Mark Rober video than me, Mark Rober? [bell chimes] [lofi music begins]
Okay, I'm gonna ask Bard for an idea, but first we need to calibrate
this thing's accuracy. [keyboard clicking]
Who is the most handsome science YouTuber? Come on, Bard. [Voice Of Bard]
Mark Rober: American YouTuber, engineer, – inventor and educator.
– I'm blushing [Mark Rober speaking]
Bard, this is like, oh my gosh. Okay, down to business. Some ideas for a [keyboard clicking]
Mark Rober video? [voice of Bard]
Feats of engineering: The world's fastest [sound of ball being hit]
Pickleball racket.

[sound of balloon inflating]
The world's largest balloon pop and the most indestructible [detonation noise]
gingerbread house ever. [explosion sound] [no signal, TV sound]
[lofi music fades out] [Mark Rober speaking]
And so after a long back and forth with Bard, it landed on, no pun intended, making the world's most
accurate paper airplane. Now I've been wanting to
do a paper airplane video on my channel for a while, so getting Bard to just do it
for me seems like a win-win.

But an idea is nothing
without a good story. So I asked Bard for the story structure in a typical Mark Rober video. First step, design. [spray paint hiss]
[upbeat drum music begins] [voice of Bard]
Exploring paper airplane designs. Start by delving
into classic airplane designs. Paper airplane design is an artful blend of creativity [paper cutting sound]
and scientific principles. [voice of Mark Rober]
From the options, I tried the Glider, the Concorde and the rather unusually named Canard. On to step two. [voice of Bard]
Defining accuracy. [voice of Mark Rober]
Bard and I talked about accuracy, wing configuration and how to test the accuracy of the three designs.

[voice of Bard]
Target practice, [plastic cups falling] hoop shots, obstacle courses and the [dart hitting board]
dart board challenge. [voice of Mark Rober]
It was the Glider versus the Concorde versus the Canard. Which of these will be the most accurate and why? [voice of Bard]
The Concorde paper airplane is likely to be [Mark laughs]
the most accurate. [Mark Rober speaking]
I hit the cameraman. I'm so sorry. [Mark Laughs] [voice of Bard]
The glider and [Mark groans]
Canard designs also have potential for good – flight performance,
– Oh man. but they may not be as
efficient as the Concorde. [Mark victoriously shouting] [Mark Rober speaking]
That is a fine example of Aerogami. And yes, Bard taught me that word. Bard called it.

It looks like the
Concorde was the closest. I wouldn't have guessed that. I would've thought Canard. But you know what? [spray paint hissing]
Now that we had our winning design, it was time to take the next step. [voice of Bard]
Optimizing the design. Sure, I can critique the
design of your paper airplane. [voice of Mark Rober]
Okay, so it's saying the wings are too small, the tail is too small,
the paper's too light and that I should use foam board instead.

[music fades out] [voice of Bard]
You need to make it bigger. [voice of Mark Rober]
Okay. Wow. Bard is challenging me, [sound of toy firing]
Mark Rober, [excited crowd shouting]
to make something bigger? It's time to call in the reinforcements. [lofi music begins] [voice of
Bard] Make the wings larger, make the tail larger,
make the folds sharper. By following these steps,
you can improve the stability and control of your airplane. [people laughing] [Mark Rober speaking]
And now for the final step.

[voice of Bard]
The ultimate accuracy test. [Mark Rober speaking]
I asked what a visually appealing and engaging test environment would look like for a Mark Rober experiment, creating the world's
most accurate airplane. "Mark could use-" [voice of Bard]
cones to mark the flight. Use a fog machine to
create a dramatic effect, sparklers to add a touch of… sparkle. Use small fireworks- [Mark Rober speaking]
"to create a grand finale." [lofi music ends]
Bard is bringing the drama. I love it. But then I asked Bard to come
up with just one more twist. [upbeat music fades in]
What's the most extreme and eye-catching way to test the accuracy and
stability of my airplane for a YouTube video? [voice of Bard]
Throw it through a ring of fire.

[Mark Rober speaking]
Challenge accepted. [upbeat music] [metal grinding] [Mark shouting] [plane launching] [Mark laughing] 'Tis but a minor scratch. Oh boy, I have terrible news. Bard, I've got like a six-foot plane here and I'm trying to fly it
through a ring of fire and it kind of stalled out. Do you think it's true
that a localized pocket of hot air would lead
to lower air pressure that would cause my plane to stall? "Yes, it is true that a
localized pocket of hot air could lead to lower air pressure, which could cause your plane to stall. Hot air is less dense than cold air." That actually makes sense. So it rises. "This rising air creates a region
of low pressure below it." That's like exactly what happened there. I think this actually helps. Keep our pressure at max, and then we're just gonna
like dart right into it, as opposed to like a high stall out.
– Here we go.

One, two, three, four, five, six, seven, eight, nine, ten. Full power, baby. 1300, let's go! Three, two, one, hit it! Oh, that's the one! That's it! That's it! That's it! Yeah! Through the ring! Normally it takes like a
year for me to go from idea to a final build like this. This only took us three
weeks thanks to Bard. Massive time saver for
every step of the process. Incredible creative collaborator
right in your pocket. Okay, time to wrap this up. Actually, let's do it this way. [keyboard clicking]
What's a good outro for a Mark Rober video? "Subscribe for more science
experiments and explosions. I'm Mark Rober and I
approve this message." If you enjoy this video,
please give it a thumbs up and a fire extinguisher. [upbeat music fades out].
