I built your dumb childhood inventions 

The OpenSauce.live roster for panels/workshops is actually ridiculous: Michael Reeves BackyardScientist Mark Rober NerdForge Jabrils CodeMiko William Osman Jake Laser Unnecessary Inventions I Did A Thing Electroboom CNC Kitchen Emily the Engineer Estefannie Code Bullet Evan and Katelyn Tom Stanton The Hacksmith Peter Sripol Jesus I'm not typing out all these names just go to OpenSauce.live

Saying "Just like Michael Jackson" feels too real after you stole a baby

I'm shocked the ceiling didn't just completely tear out

As an Australian you have no idea how welcome the invention of safety boots is. Finally, I can walk on my front porch without fear of falling into the sky. You have changed my life. Thank you, from the top of my heart.

The most impressive thing about this dude is the fact that he still has all of his appendages. 😂

Its weird as hell imagining Code Bullet as like, a dude with a human face. Somebody should make a TV helmet for him to spare the world of that lol

we need to get Audrey some riot gear body armor just for the danger of being around Allen.

dude, whoever did your ceiling drywall needs a BIG raise

imagine being his neighbor and seein this shit every day. Lucky bastards.

I love how Kevin just casually owns everything ever.

Only Alan would have weeds growing out of fake grass.

You should try making gloves that let you shoot out force lightning, like how Palpatine does it

If you really think about it his man can gather all of his tech that he has made all over the years and become a real life super villain

The fact the ceiling shoes actually worked is genuinely impressive

Awesome irresponsible projects! Love them! For the laser sword you should have used a retroreflector! See you at Open Sauce!

1 - I can't believe them upside down boots worked 2 - I'm surprised that didn't rip a huge chunk of your ceiling down. Respect to you and the builders 😂

I love how every second science tech youtuber is a real life mad scientist, it's just so authentic. Who else have you seen stealing a baby to use as a random ideas generator?

I love how all his neighbors have nice yards and he just has 4 foot weeds everywhere

Bro, after all you’ve done for the snakes, you shouldn’t be stressing over new invention ideas. You’re already a living legend ❤

4:06 goofy ahhhh fall😂😂😂😂

imagine breaking into a home and you just hear "babe, grab me my laser gun." i did not know that those were even a thing. that seems like an amazing self defense tool. light speed incapacitation to the eyes.

Damn, the CGI for Chainsaw Man season 2 is looking crazy good 😳

CONGRATULATIONS ON 2 MILLION SUBS!!🥳🥳🥳

stealing a child purely to make decisions for you is the most in-character thing ever

The ceiling shoes would probably work really, really well with some sort of brace that prevented your legs from dropping too far down, something that forces your leg to stay relatively straight up. Not regarding to bloodflow problems, of course.

You clearly needed a builder from Australia for upside walking.

The lawn mower boot is something straight out of something I would have expected I did a thing to make

Let's give a round of applause to the drywall that was holding him up. Very well-built ceiling

Dude had so much trust in that ceiling paint

This is peak science. I love the use of couch cushion safety pads.

I'm so happy you have friends like the backdoor scientist to help you with these projects

him: sidesteps his grass to death

bro just casually made the single best invention with the first one

the reason why the mirror thing didn't work with Kevin's laser is because it uses an infrared wavelength, and regular mirrors act like non-reflective objects for them. For IR light, you need a gold or gold plated mirror.

3:23 Props to the camera man for using his physic powers to walk on the ceiling with him without the suction boots!

When BackyardScientist pulls something off, it's got to be extreme but he keeps blowing my mind

I love your concrete safety protocols. New subscriber here and I just appreciate your safety-first approach!

Dammit Allen you’re genuinely one of the coolest creators out there. Don’t go hurting yourself for our entertainment.

We are in the renaissance of sketchy RU-vidr engineering and I'm here for it.

I love how some of these are built like a toddler made them and planned them

can u just appreciate how a baby is lying down on the counter top 3:56

So am I the only one who noticed Allens design for his Lightsaber is really freaking similar to that of a Beam Katana from No More Heroes? i'm sure Travis would be proud

6:41 back door scientist got me 😂😂

@Allen Pan the part where you are on the ceiling is the hardest I have ever laughed in my entire life

FOR A SECOND I THOUGHT HE WASHED IT WITH A HOSE LOL 13:29

ProTip: For the laser sword, don't use a mirror. Use a "retro-reflector". Retroreflectors always reflect the light(or radar) back to their source. It's how street signs and bicycle reflectors work internally. :)

I'm surprised the ceiling could hold your weight for so long

Man Allen is soooo lucky that ceiling is built to code. Here in Missouri there would have been soooo much more coming down with him.

Warning label on the laptop pretty well sums up the internet. Glad you're in the hole with us, Allen.

Allen looks 150% more Asian when turned upside down 3:17

The suction boots could’ve been a whole video, props to you for doing more than the bare minimum!

As soon as you put your weight on the ceiling I knew you were gonna crack the sheet rock up there. Surprisingly it wasn't too bad

I've ran out of video ideas.... becomes the first man to walk upside down on the ceiling! Impressive!

Now I know why it takes CodeBullet so long to post, he is hanging out with you geniuses.

God bless Audrey for putting up with your antics

allen designed and printed a whole part to avoid drilling one hole in a plunger

I like how the suction shoes and the grapple plunger were just lesser versions of what J laser already made with his Spider-Man stuff

8:10 What the hell, CodeBullet? I didn't expect to ever see this crossover what.

I definitely saw the laser burning right through the mirrors coming. Many research grade mirrors would be damaged by that welding laser.

Damnnnn those ceiling shoes worked perfectly, honestly easier walking upside down then up a wall 😂😂

2:44 this whole entire thing, up till when he falls, is probably like a baby learning how to walk. And what they are thinking

Jesus Christ the lawnmower boots have got to be the most anxiety inducing invention that I have ever witnessed

all Allen needed to do was add a shaky light to the laser sword and he'd be a leather jacket away from being Travis Touchdown.

"I found this plunger from a cartoon, and then- urm- hammered a THING onto it to pull some.. STRING through." "It's, I- ugrh- I got tired of.. filming.... things.."

The Belle Delphine RU-vid in the background at 0:51 cracked me up

Ai can have someone who sounds just like a person who can look just like you that can find all of your info, no nothing to worry about here, which is why its good to laugh at your videos that first part was hilarious!!

I love the ongoing joke of him just stealing everything

Allen does it again 😀

POV 12:20 You told the barber a little off the top

dude walked on the ceiling like a cartoon character.. broke what i thought was impossible alright i love sceince

Wait till you research the thickness of drywall, and how it's only held on by a screw every few feet. That will terrify you!! Great work those are amazing.

I’m sure your neighbors are glad one of your video ideas finally included a landscaping invention. 😂

Child:Mum I want chainsaw man Mum:we have chainsaw man at home Chainsaw man at home: 11:19

This man’s trust in dry wall is unreal

6:10 this is absolutely incredible to see the photons pushing the balloon away what an amazing accidental demonstration of physics 🤣

Allan lives in such a cool community where people not only let you borrow suction cups, but let you borrow you their cars and babies too

im amazed there was so little damage to the dry wall ceiling

Hey never mind about the North conarmer. I had idea use to make one for your hands where you could grab on duty walls for your feet on and have a separate 1 for the hand you're. Like turn one eats off at a time the walk up.

I mean Allen technically isn't wrong when he is referring a baby to a neural network. After all, the brain is just the sum of almost a hundred billion neurons

Ok so we've got: Ceiling climbing shoes powered by angry cows. A lightsaber but the blade acts like a wet noodle that cuts things and will blind you instantly. A pair of -ankle remover- weedeater shoes. Neat! 😁

Those suction shoes were actually a great idea. But I think the ceiling wasn't perfect. Suction cups work better on smooth materials, like tiles, than on rough ones, like plaster. I suggest trying these out in different rooms.

Honestly, i was waiting for the drywall to break with those suction shoes lol

8:50 wow One of you guys finally pulled off a decent explaination of what opensauce is.

12:30, does him saying myth confirmed mean he already knows what the test looks like on a human skull?

Neighbors: “Everyone come back inside, quick! It’s that inventor guy again-he’s got a plunger, now!”

This guy is just stealing everything and I'm all for it Love your stuff

A cool idea for the lawnmower boots is to add a leafblower to the sticks to move the debris out of the way

All these inventions are all so good that they deserve their own video.

When I was a kid I drew out a blue print for my invention called the frosterwave basically it’s a microwave that freezes things or cools them down to whatever temp you’d like. It looks like a microwave but it uses liquid nitrogen to cool things or freezes things! 😃

Honestly the laser sword idea is basicslly just Travis Touchdown's laser katana from No More Heroes

10:15 note to self: plungers don't make accurate projectiles

6:45 the boys casually making futuristic energy blasters

I thought that the whole panel of ceiling drywall would be coming down rather than just that little chunk. Honestly surprised he didn't mess up the walls too.

my childhood invention was combining scooter with bicycle basicly you took of front wheel from bicycle and attached the bicycle with just rear wheel directly to back of the scooter it worked very well one dude had to padle on bicycle and other dude was sitting on handlebars and used scooter to steer (as scooter i mean the one with no motor)

For the "laser sword", when using the first laser: 1. Need a stronger pole for holding the mirror at the top, antenna has too much flex. 2. At the top and bottom use a faceted mirror "cup" that redirects any beams coming into them into the center. 3. Offset the laser emitter slightly off of the bottom cup so laser doesn't get redirected into laser head. By doing this you should be able to get an "infinity mirror" type setup between the two "cups" and any movement in the beam should be redirected towards center of "cup" before being sent to the other cup.

I remember on myth busters they did a vacuum suction cup setup but it was waaay bulkier and didnt work nearly as well. Im sure a lot of their movie myths would be cool to back back and try with new tech.

The first idea only made me think "how strong is his sheetrock," then his sheetrock broke

You're a legend for putting the sponsor segment at the end of the video.

Chainsaw boots: The new way to mow your lawn.

3:35 Bro became morty
