  • - You wanna see it kicking back in normal conditions

  • and you wanna test it in not-so-normal conditions

  • until that's not kickback, you wanna give it all

  • of the edge cases so it know what's going on.

  • - [Destin] Why are you smiling, why are you smiling?

  • (laughing)

  • - I think we should test the edge cases.

  • - I normally say, "Hey, it's me Destin,

  • "welcome back to Smarter Every Day,"

  • but there's nothin' smart about this.

  • So here's the deal, this is a rocket saw

  • and I wanna say I'm sorry but I'm totally not.

  • Here's the deal, here's how we got here.

  • So in the last video, we explained

  • how we had incorporated machine learning

  • into power tools in order to keep them

  • from hurting you, right?

  • So the way you work with a machine learning algorithm

  • is you get a really big fancy computer

  • and you start to sort events out

  • like data collection events.

  • In our case, normal use of a saw

  • so we see like a normal thing that happens with a saw,

  • we put it in the normal bucket, right?

  • But as we see these things that are dangerous,

  • we would put those over here in the dangerous pile

  • and if you do this enough, eventually the computer

  • can sort between dangerous events and normal events.

  • You can't test everything in the world,

  • okay so you come up with all these really weird things

  • and you do your best to like sort 'em out

  • but eventually you get to the edge cases

  • and you have to make a decision

  • like as a human, where do these things go?

  • One of those things we thought about was a rocket saw.

  • Obviously the rocket saw's gonna go

  • in the danger pile and we're not actually gonna

  • collect data on this shot but we thought

  • about a rocket saw and once you realize

  • you're smart enough to make a rocket saw--

  • So we got a rocket powered saw

  • and we're gonna see what happens.

  • I think it's just gonna stop back there.

  • I don't think it's gonna make it this far, do you?

  • - [Man] Yeah, no bets buddy.

  • - [Destin] Four rockets, we got two Fs and two Ds.

  • - If only we had five.

  • - [Destin] If only we had fire.

  • And you've got it all wired up, ready to go, right?

  • - [Man] Yeah.

  • - [Destin] This GoPro lookin' back at the blade

  • is gonna be nice.

  • Like the GoPro should see the engagement of the teeth

  • and stuff, this is so dumb, I love it.

  • (saw running)

  • I think it makes--

  • (laughing)

  • Alright, you're tall, you gotta turn that beast on.

  • So it's ready to fire, right?

  • You've got the thing wired up, right?

  • - Right. - Okay.

  • This is one of the more noble things

  • I've ever done in my life.

  • Now would be an excellent time

  • to make a prediction on what you think

  • this thing is gonna do to the wood.

  • Also, the very first video I ever uploaded

  • to this channel, called, "How to Light

  • "a Bonfire with Rockets," cringe-worthy.

  • It's like the first video ever made.

  • It also involves shooting a rocket

  • from this exact same tree.

  • (beeping)

  • (saw running)

  • Alright, lemme go arm the high-speed camera.

  • - [Man] Oh my god.

  • (laughing)

  • (saw running)

  • Three, two, holy crap, one.

  • (rocket whizzing)

  • One!

  • (rocket whizzing)

  • (laughing)

  • What happened?

  • Holy crap.

  • - [Destin] Get the GoPro before it catches on fire.

  • - [Man] If it's still there.

  • - [Destin] Oh, it's still there.

  • - [Man] Is it still there? - Oh!

  • (laughing)

  • Totally survived.

  • - [Man] It bounced up. - [Destin] Yeah I don't even

  • think, like it didn't even try.

  • It didn't even try. - [Man] It just rolled on it.

  • - [Man 2] We got it man. - [Destin] Did we, dude?

  • We totally did, oh!

  • (laughing)

  • (slow motion rocket whizzing)

  • That's a thing you can do with friends.

  • - [Man] On a Friday night. - Who needs drugs when

  • you can do stuff like this, right?

  • Let's zoom in closer and see if the saw blade

  • does what you thought it would do.

  • (laughing)

  • Oh my goodness, my heart.

  • Oh it just dinged the screen?

  • Who cares, did you see what we just did with that?

  • (laughing)

  • This episode of Smarter Every Day

  • is sponsored by Casper Mattress and Prince Rupert and I

  • are going to unbox a Casper Mattress for you.

  • No, come here.

  • (meowing)

  • This mattress is called The Wave.

  • The Wave is designed specifically for the needs

  • of side sleepers like my wife and I.

  • The whole deal here is that it has

  • a perforated breathable memory foam

  • to keep your spine aligned during the night

  • and keep you cool because it's breathable.

  • As you press on something, the amount of squish

  • is a function of the elasticity of the material.

  • The fancy thing they've done with The Wave

  • is they've varied the elasticity

  • from the head to the foot of the bed

  • so you get more elasticity around the shoulder areas

  • cause most people's shoulders are wider than their hips

  • so it aligns your spine as you sleep

  • on your side which is a big stinkin' deal

  • because my wife is a side sleeper.

  • First two nights with Casper Wave, what do you think?

  • - I like it, I like it.

  • Am I supposed to look at the camera

  • or am I supposed to look at you?

  • - [Destin] Does it matter?

  • You wanted a side sleepin' mattress,

  • does it do what you need?

  • - I did want one, it does what I need, absolutely.

  • - All Wave purchases come with a free

  • in-home set-up and a hundred night trial.

  • If you don't like it, let 'em know,

  • they'll come get it, no questions asked.

  • Their pillows are also awesome by the way,

  • we've got the soft layer on the outside

  • and a firm layer on the inside

  • so each side of the pillow feels like

  • the cool side of the pillow.

  • They didn't ask me to talk about the pillows,

  • I asked them if I could talk about their pillows.

  • You can get 50 dollars off a core mattress

  • or a hundred dollars off The Wave mattress

  • which is ideal for side sleeping

  • if you go to Casper.com/smarter

  • use the promo code smarter at checkout,

  • you're gonna get a better night's sleep,

  • they have engineers workin' on this stuff.

  • You're still here which means you understand.

  • We're both winnin' here, my whole life

  • led up to this moment to make the rocket saw.

  • Your whole life led up to watching this video,

  • we're all winners.

  • Thanks.

  • There was a smart reason that

  • we got to that point, I promise.

  • - I think we yelled, "For science!" several times.

  • - Yeah, that's how that works.

  • Alright, well, you're getting smarter every day.

  • Have a good one, thanks for watchin'.

- You wanna see it kicking back in normal conditions
