The holiday season is upon us and you know what that means?
It's time for another Maker's Secret Santa.
And it's our biggest one yet with 12 different makers.
We've got Kids Invent Stuff
James Rooten, Estefannie Allen Pan, Thea Ulrich.
Look Mum No Computer, me, Colin Furze, Zila Foxlin, Jen Mel and Katie from Tested
Becky Stern and This old Tony, it's going to be an exciting one.
Whose gifts are you most excited for?
Last year, we made an epic led sign for Kids Invent Stuff.
And before that, our first Secret Santa, we made the red nuclear
microphone for all the makers involved.
This year, our Secret Santa recipient is a newcomer to the group Thea Ulrich.
And if you're not already subscribed to her, you're missing out.
He is a bad-ass maker, steam educator, artist, welder, circus, performer,
lover of fire, and more... she's even toyed with a few, Make It Real style
projects in collaboration with Kyle Hill.
Plus just this summer, she glitter bomb the glitter bomber himself, Mark Rober.
With so many talents and interests.
How are we going to make her a gift?
Well, I think it's going to need fire for one, probably some welding,
though I'm a little nervous and she's a way better than I am.
It should also demonstrate some educational concepts since we're both STEAM educators
and it should enable creative expression in a fun way.
I think I have the perfect idea.
Have you ever heard of a Ruben's tube?
Now, I learned about these back in college.
It's essentially a very long propane burner, almost like a barbecue,
but it has a speaker inside of it.
And since sound is actually a pressure wave.
When you play sound inside of the tube, it actually creates a differential
in the pressure for the gas, which changes the amount of fire that comes
out of the pipe, which basically means you're creating a fire equalizer.
Normally you install the speaker inside the tube, but the issue with this is
the sound usually becomes muffled.
So if you're trying to play music, you can barely hear it.
Luckily, I found these small metal Bluetooth speakers that
actually have a base diaphragm in the bottom and a speaker on top.
This means if we attach a tube to the outside edge, we can have crystal
clear audio coming out of the speaker and the base diaphragm will cause the
pressure waves in the pipe to give us a Ruben's tube.
To make sure my idea works.
I actually prototyped a brass Rubens tube.
I chose brass because the holes you have to drill are very small
and brass is very easy to machine.
I have attached to my speaker to the end.
I've got my inlet on the back, filled with propane, and now as soon as I pair
the speaker, turn on the gas and light the fire, we're going to see some magic.
That is pretty cool.
As you can see, when the bass drops in the song, the flames get really
big and that's because the sound wave is creating so much pressure.
It's actually pushing the gas out of the holes faster.
Sometimes the flames go out and then they relight.
Coming back? Ready for the base in 3, 2, 1.
Dancing fire.
This portion of the video is sponsored by Google Pixel 6.
We've put a lot of time and effort into our projects and videos.
And I think that's evidenced on screen, but the one thing that probably isn't as
obvious is the amount of effort that goes into making the thumbnail for each video.
Thumbnails are very important.
We need to grab your attention with a single image.
The pixel six is a really cool device.
We love the awesome features that allow us to capture our creative ideas.
It's actually quickly become our go-to device for capturing thumbnails.
For us, capturing the moment is our main focus and the Magic Eraser tool lets
us quickly and easily remove unwanted distractions from the background.
This way, your focus is right where you want it every time.
On top of that, the Face Unblur tool and Motion Mode are lifesavers.
The Pixel 6 camera simply captures action shots, other phones just can't.
The Pixel 6 lets me, be me.
And of course let's not forget.
It's a great phone.
Today's video is all about connecting and sharing with friends regardless
of where we might be geographically.
This is the fastest pixel ever. Pair it with T-Mobile and you have the fastest
Pixel ever on the fastest 5g network.
So this season, why not treat yourself, check out the
Google Pixel 6 on the Google store today.
Thanks Google Pixel 6 for sponsoring a portion of today's video.
Now back to our regular content.
Since Thea and I are both steam educators, I'm going
to try and combine all five topics of STEAM into this gift.
For science, we're using sound pressure to change the flow of gas to create the effect.
For technology, you know I'm going to use some of my awesome
CNC equipment to help manufacture it.
For engineering I'll be designing it first on the computer using Computer Aided Design.
For art.
Well, I'm going to make this Ruben's too like no Rubens tube before...
a stainless steel monolith of fire.
Finally, we have mathematics.. when playing a known frequency through the Rubens tube,
we can create a standing wave effect and using this calculation, we can actually
calculate the speed of gas flow inside of the tube.
Pretty cool right?
Now I've actually already thrown together a quick design in CAD
and I think it looks pretty good, but it is kind of boring.
How can we make it a bit cooler?
I think we should do something that kind of lets people know what it does.
So I'm thinking of probably look really cool.
If we put a wave form on the front since Ruben's tube is
basically a fire equalizer.
Now, should the wave form be of some famous music riff or
maybe just something on the nose.
Like saying Thea's name...Thea Ulrich.
That looks pretty good.
I'm a gosh darn artist!
Now, unfortunately there's no real easy way to decode a wave form.
So no one's actually ever going to know that this wave form says Thea Ulrich.
So why don't we put her logo on the side and that's going to be really
easy to do because her logo is actually in the shape of a triangle
And there you have it.
The finished design, I think it looks pretty.
And as you can see, I've got my propane tank hidden underneath.
So the neat thing is when you look at this, you'll have no idea that
it's capable of making music or fire, which I think is pretty neat.
It's time to manufacture it.
We're going to have to laser cut some pieces, and then we're going to have to
CNC those holes into that pipe.
Let's get started.
for this Rubens' tube to work.
We need really small holes drilled into the stainless steel pipe.
I hope this works.
Oh, that looks pretty good.
We've got all the parts made and they are looking great.
I had all the laser cut parts polished in a nice and shiny and
bringing out that stainless steel.
So let's do a test fit.
And it looks pretty awesome since the test fit worked, it's time
to actually weld it together.
And the first step will be adding these black backer plate.
To the backs of each of my stainless steel plates to give us a nice crisp
outline for our laser cut wave form.
But that looks really good.
Yeah.
Now we just have to tack weld the entire thing together.
So the tricky part now is I need to put the tube in, straighten this
up, tack weld the rest in place.
Then I can put some more actual seam welds in to make it nice and strong.
But I'm not too sure how well placing the tubes getting in is going to go.
So...let's see what happens.
We've got that all welded up and it's definitely not going anywhere,
but unfortunately, since I'm not a great welder, there's tons of color
change and the stainless, which technically means I didn't do a good
job welding, but I already knew that maybe Thea can teach me sometime.
Luckily, we can use the power of chemistry to hopefully remove
any of this discoloration.
So we're going to be using sine called electrochemical polishing
and how that works is we use this nice little chemical here.
We run power through this grounded, to the other end and hypothetically.
Too much power.
That kind of worked.
It got rid of most of the color, but it actually left the burn marks
behind, which kind of makes sense.
It's not really a fix-all.
Which means we're up to the buffing wheel.
There we go.
Going to use some contacts cement to
Hopefully permanently install these speakers.
It's important we get a really good seal when we glue these speakers in, because
we don't want any gas getting out.
I've used a copious amount of rubber cement, and I'm really
hoping this works...feels pretty snug.
Hopefully that works.
And now we wait..
While I was working on Thea's gift, my gift showed up in the mail.
And this is the biggest secret Santa gift I've seen yet.
Contents: can easily be sliced, use lightsabers or blades cautiously..
some weight to it.
It feels squishy.
Alright. Let's see.
Got me worried.
Okay.
It's pink.
What the heck is it is just a giant yoga mat.
What
is it?
A couch.
Oh, there's that?
There's a cookie tin in there too.
This is a couch.
This is most certainly a couch and cookies for the Hacksmith team.
Take one.
You're the Hacksmith team.
I mean, maybe I should just read the card.
It does appear to be a couch backpack.
So.
I guess I'll put it on.
It is a portable sofa.
Then the sofa unfolds, it straps to your back, lightweight and
very comfortable invented by Sofia.
Merry Christmas Hacksmith crew.
Here's the thing from us to you.
We noticed you all work too hard.
Now here's the present and a card. To help you chill when
Things get stacked. A portable sofa for your back.
Designed by Sophia who's 10 years old
and engineered by us to bend a fold. Just strap it on and you're away then sit and clip and chill all day.
Happy Secret Santa!
That is ridiculous, but awesome!
Let's try it out.
I don't want to full send it.
This is a concrete floor.
Okay.
Step one.
Where using straps. Step two, put sofa on back using straps.
Step three, walk around wearing a sofa.
Step four, sit down when tired.
Step five secure sofa with side clips.
Oh, can you, can you clip that for me?
Yeah, there we go.
Oh, wow.
Now I can actually lean back.
There's straps.
Is this the one Charles ran into the Cyber truck? Ben get over here.
Fits three people comfortably.
Oh boy, here we go.
Yeah, Merry.. and we got some chocolates.
Oh right you're allergic to chocolate.
That's my portable sofa.
That way, when I'm tired, I can just sit down.
I gotta say this is probably the most unique gift I've ever got.
So here's to get the kids invent stuff and Sophia for inventing such
a useful invention, going to go far kid.
So I came back last night to see if it worked, but the glue didn't hold.
So I actually ended up JB welding, the speakers in place, which
is why we're clamped like this.
But JB weld should have cured, feels pretty strong...thread on a bottle of propane.
Grab my handy-dandy mini saber, open up the propane.
I think we want about a one inch flame.
Now we can go ahead and.
turn on our speakers.
So we got a steady flame.
We can lift this up very gently, hide the propane tank inside.
Ooh.
Now let's, uh, let's play some music.
Here comes the base.
Fire equalizer.
I going to show you one more thing here.
So now we can do a frequency generator.
So we adjust it very carefully.
See, I can make that wave, move back and forth.
Well, there we go.
See,
We're literally seeing.
basically a wave form.
I think that works pretty good.
Should probably make an instruction manual for it though.
Cause, uh, it's not the, not the most intuitive thing to use, which
is part of the design too, because when you look at it, I don't think
anyone's gonna think it makes fire.
Until you light it on fire, which is the best thing about fire.
You never expect it.
There we go.
Well Thea,
I hope you like your Secret Santa gift.
