I love how this man either makes things that seem like they would be fun toys, or makes things that are obviously weapons designed for war crimes

I happen to have extremely specific expertise on this as R&D chemist at a candy factory, so here's a recipe for the ideal candy gun syrup: Add sugar, corn syrup, and water in ratio 60:30:10, melt, mix together, and then boil it down without stirring until it hits 150*C, heavy bottom pot is best. Once it hits 150*C, mix in 3% by weight glycerin, then go do your shenanigans with it. It will be way less viscous, won't make the icicles, won't burn, and turn into way more and longer strings. The reason for doing these things is classified/arcane knowledge. Oh also be sure to empty the pot of any syrup when you're done. If you let a thick layer solidify in there it is *hell* getting it out.

I gotta figure out how to make Mark Rober to fire me

the plants across the garage have definitely suffered a lot of abuse

who knew making a cotton candy gun was rocket science

Dude, you don't have to rush your videos. Every second is solid gold and I wouldn't mind at all if you made them a little longer. This was too cool.

Ok props for the awesome lady at the fair who when asked to open a cotton candy vending machine was just like "yeah sure"

Honestly I feel like the biggest achievement you have done here is fulfilled an ants life long dream your back yard is going to have such a thriving colony after this experiment.

I love how this man takes one of the least threatening sugary treats and makes it into a terrifying weapon.

One time I was at a mall and I saw that cotton candy robot and it was making weird looking flowers and just dumping them in the back of itself over and over again. We decided it would probably start a fire if too much got in there so we took one and it seemed to stop auto firing cotton candy 😂

Only a backyard scientist could weaponize projectile cotton candy

I was surprised after the pouring worked so well that you didn't build a gravity fed tank that just poured the sugar infront of the nozel when you opened a valve. Though the cotten candy cannon with the fire extinguisher was my personal favourite. Like a party popper but with molten sugar and cotten candy instead of confetti 😅

Infusing sugar with Prime and spraying it all over the grass? You're practically inviting ants to get superpowers. Some unfortunate soul will end up being bitten and transformed into a *real* Antman. Not just some guy that can change size, but someone with a super-strong exoskeleton complete with six legs and sudden cravings for picnic leftovers.

let's have a minute of silence for the poor plants in the alleyway which have been through a lot over the years

on 5:30 he literally made a edible web shooter😂

2:47 "Wow, You don't know how many times it took for me to get that right" That was great!

This reminds me of a couple decades ago when I discovered you could shoot hot glue from a hot glue gun into an air compressor stream and send glue spider webs everywhere. :)

3:35 "I didn't make cotton candy, I made an afterburner" best thing I've heard in a while

5:42 Allen Pan is far more than Mark Rober's assistant!

I just wanna point out, 8:25 he is wearing gloves. I work at a steel foundry pouring 2800 degree steel and we use the same gloves lol. (For working after the steel is poured, when we are pouring it we put on the big silver suits).

6:40 congrats! you made an annular booster! its the next step in better carburation over a down leg booster which is kind of similar to you just pouring the molten sugar into the air stream really cool how you gout to the same spot.

02:39 Unfortunate bystander chosen for execution for a fun sugar shooting machine 😀.

"You won't hear anything. Hopefully you'll just see cotton candy." Okay do I at least get a blindfold.

This man casually said "I'm gonna use my jet engine i made last year" this guy's one bad day away from being a super villain😂

after seeing the leaf blower work i had an idea ideal gas law says going from high pressure to low pressure results in cooling. if you put short to wide nozzle after the compressor but before the hot sugar, it should keep the air warm enough to keep the sugar from turning solid without loosing too much kinetic throwing energy. Also your sugar injection system should be on the top so the sugar falls into the air stream. Instead of venturi or internal pressure, use a physical piston and gasket compression instead. This keeps air from escaping the cylinder instead of the more viscus sugar. work on different designs for the injection plate, as the civ seemed to have success with lots of nearby holes in an array rather than a single row of small holes you seem to be designing towards. Doing it this way also should let you put a "butt fusion" heater assembly mounted to the gun to heat the sugar while in use, instead of rushing to mount a hot sugar to the gun before use

The backyard scientist once again emerges from his florida abode. This is freaking awesome!

9:10 Even stickier that those times about 4 years ago, when you made human-sized glue traps?

4:51 Hey, it's my giant keyboard!

1:48 “Look at that! It’s twerking! It’s twerking! It’s twerking, no!” -TheBackyardScientist

rocket powered cotton candy is possibly the greatest idea of all time

A tank with a gravity feed would and a decent valve probably work just as well as just pouring it into the stream. And it would give you the added advatages of being able to use both hands for holding the device, and have a perfectly controllable flow of sugar. Basically; instead of trying to fight gravity, use it.

The Open Sauce line-up looks amazing. It's great to see people like Evan & Katelyn attending. I really wish I didn't live so far away.

Instead of melting all the sugar at once, I’d use some sort of heating element to melt the sugar just before it comes out of the tube, and then blast it with air to cool it down again

Ants from far and wide are still telling tales about the legendary promised land where everything is covered in sugar.

I would suggest trying to build something more closely related to a large airbrush, except rather than attaching the cup directly to the nozzle, you suspend the cup above and out in front of the nozzle on a bracket Inside the cup would be one or more heating elements to heat the sugar for you (Instead of heating it beforehand and having to act quickly), with a valve to open and close it, letting gravity do all the work.

I like how it basically turned into one of those spiderweb guns for movie sets.

If you want an ant infestation in your backyard, this is how you do it.

The man, the myth, the legend.

9:05 that’s what she said

I made a tiny one for blowing “spider webs” onto a display before, but definitely nothing to this scale, this is awesome. I used the more brute force method of flame heating the connection X-p didnt last long, but made a cool diorama (using weaker air from a compressed air can may have also helped)

YOUR MOM IS MY SCIENCE TEACHER

He worked so hard on prototyping this and then just breezed through it like it was no big deal. ❤

Would love to see a longer version with all those other things that you tried, love the content

2:04 a semen demon

The ultimate ant machine. You want ants? THIS is how you gets ants.

“This is a rocket engine I made (for a video last year)” is not something anyone can say except this man

The sweetest and most dangerous science experiment I've ever seen xD

I haven't finished the video but the part where you were pouring the liquid down and spraying it and then it was finally working reminds me the movie industry figured out a way to spray I think it was like a melted plastic to make artificial cobwebs on everything so maybe you want to kind of look there to get it kind of different idea

4:09 That contact panel got me acting unwise, my oh my. What a gorgeous rear view.

One day in the land of the ants, the sky began to rain down sugar, and all the ants rejoiced.

Kevin's videos are a perfect example of the phrase "that escalated quickly". Start with an air compressor to make a cotton candy launcher, immediate next step? Rocket engine.

4:26 lmao

I know the steps on how to make a cotton candy gun in 5 steps Step 1 : Make molten sugar Step 2 : Put molten sugar into metal container Step 3 : Take 2 large propane stove burners and set them to high, take some high temperature piping connecting them with a stream of compressed air Step 4 : Make a venturi nozzle to fit between the high temperature piping and the molten sugar Step 5 : Activate the compressed air

"I didn't make cotton candy, I made an afterburner" That's probably the first time those words have been spoken in that order

2:19 come

was that rocket league in the background???? 5:49

”I didn’t make cotton candy, I made an afterburner” give me the same vibes as “I came looking for copper and found I gold”

I love how this guy’s not scared by knife missiles and giant bear traps, but is terrified of molten sugar

1:53 my nose at night be like:

7:58 is where the promo ends

this man has inspired me to do a lot. thank you

2:26 the part where he goes completely insane

Surfshark uses old MD5 hash encryption techniques which were cracked decades ago. Now they do intertwine hashes to make some kind of weird semi-hash thing, but still it can easily be cracked. I've actually cracked it myself and It took 2 days, but considering modern encryption techniques take years to decades to crack, I did pretty well! So the point is... Yeah unless you want your data stolen in 2-4 days, DON'T use Surfshark - An Actual Software Engineer

This man gets a good idea and DOES NOT stop until the product is perfect/ exactly what he thought of. He doesn't care about how low the frequency of his uploads is, but the quality of each vid is op.

Can we just appreciate for a second how much time and energy and money gets spent to make these videos. You sir are a legend.

I thought the CIA kidnapped you to make some secret technology for them lol

I swear you will definitely have an ant infestation. I mean literally every insect on the planet gonna be at your house

Me after November 6:10

Always glad to see backyard scientist post! Keep up the good work!

Love the ideas, keep the great work coming

Nobody: Every Florida Man: "I didn't make cotton candy, I made an afterburner..."

"i didn't make cotton candy, i made an afterburner." common mistake, we've all done it

Can't wait to show this to my kids 😊.

You do not disappoint with these uploads!

"I'm actually eating it!" "Well, I just wanted to kiss you." Well, there's a new ship I didn't know existed

I think that “Ididathing” and TheBackyardScientist would have a really fun time together! It would be very nice to see them collab

well im sure the ants are gonna love this

Thank you for all the things you make!

This is the same process like making rockwool. The key is air speed that is actually pretty "sedate" and and the molten sugar needs time to "pre cool" a bit before hitting the air stream. This way you create skin layer that then gets stretched out. This is essentially what you did at the end of the video.

I'm surprised the induction heater didn't make an appearance in this one.

In 50 seconds, you described the Venturi effect much faster, and with more interesting applications than getting my mechanical engineering certs ever did.

"I didn't make Cotton Candy, I made an afterburner" casual problems, you run into....

Mark Rober and TheBackyardScientist seem like a perfect science duo.

3:35 "I didn't make cotton candy, I made an afterburner" Yeah hate it when that happens.

“I didn’t think I would be summoning a demon from the nozzle” is such a hilarious yet worrying line

Sugestion from The Ionizer - Spinning the surgar will allow it to move only when it’s melted keeping it from burning. If you have a cone to bring the liquid to a center and also have some channels to flow . The idea is to fling it out in as narrow and fine as posible to give you thread. You use nozzles at that size will clog. Better experiment would love to help you with is how about a different type of heater. I can explain how a machine works and how useing a wireless way to heat a spinning chamber can work better and be better controled. works can have huge improvements.

Your backyard is about to get swarmed by 2.1million ants

man, a new backyardscientist video feels like christmas because its always a GAD DAMN GIFT

At the beginning it looked like spider man web shooters

This might be your most important and historically significant invention.

"Do you want ants? Because that's how you get ants." - Sun Tzu

The amount of ants this guy must've summoned by doing this would just mind blowing. I seriously could only imagine

10 dollar cotton candy got me

Imagine a kid at a theme park wants cotton candy and someone pulls out this thing

"I didn't make cotton candy, I made an afterburner!" has to be the hardest quote in science RU-vid history.

That cotton candy machine is just sad , I used to love buying it and seeing the guy doing tricks and looked awesome

"Do you want ants? Because that's how you get ants"

A gun that turns things into candy hasn't even been done in video games before lmao

if you want to skip the sponsor it ends at 7:57
