K40 Laser vs. Starlite Super Insulator / Testing what Recipe really works

Hey can you try the recipe that everyone tries: cornstarch whatever amount you
want but the baking soda needs to be 10% of the cornstarch. Then Elmer’s glue mixing to a putty or dough consistency. Then try your laser. This would really help and be awesome!!
Thank you!!

someone take a damn plasma torch to it already

I am going to "experiment" using oil-based primer for the liquid, with borax and baking soda., and see what happens! ;- )

What if you could use this as a protection against shaped charges for military equipment and vehicles

Also what is the temperature of the laser?

What is the strobe thingy on your desk... looks cool and where do I get one? Great video!

impressive well designed & documented tests. impressive performing mixture too.

A little backround to this. If you look at the Structur of starch woodglue and backingsoda and do a binding energy comparison, you ll see that basically all binding energys are close together and that a huge amount of gasses are produced. in my oppinion 4 to 5 mol per mol of material. My theorem is that this stabilises the temperatur of the carbon enough to not just form layered carbon(graphene) but a interconnected multilayered carbon foram which makes it really really hard for oxygene to attack the carbon efficently. To this it appears that the Na+ that is sourced by the baking soda will form a connective salt between carbon structures plus it doubles as victim for aporoaching oxigen. And evenfurthermore at really high temps not even Oxigene should beable to harm the carbon layer anymore sinde the temp is so high that the binding energys will just be brocken instantaniuosly even between co2 and cc which in turn releases c+ gas and depending on what structure this means that you basically will have a last resort insulating c+ gaslayer forming i guess.
In essence you can take the second disk as a series of carbon structure systems forming Graphene buckyballs carbonnanotubes which all have a high ressiliance to oxigen and in the end you recive atomised carbon+(plasma) which as soon as it is cold enough forms co2 which is visible as the nice orrange flame at the end of your burn.

Have you done time till penetration with your laser? care to tell us how long it took your laser to penetrate?

You could put a paper under the black bread to check if it penetrated or not. Not sure why you were trying so hard to find that hole in the black bread

If you any equipment to produce radiation, Can you test it if its like radiation-resistant. Or maybe just microwave and see if it holds up?

Ask yourself ...historically he was a hairdresser...the use of asbestos was common in the air dryers and masking clay etc + your binders Poly Vinyl Alcohol, Silicates, boron, bicarbonates/limestone etc common off the shelf stuff....my theory why he never disclosed formula was the negative press on asbestos that was evolving in that time period...BTW which he blew in the face of everyone of his customers that required a hair dryer so plenty of friable asbestos available from those broken tools of the tinkers trade.

how about crushing up the carbonized bread and adding that to the mix, then shooting it with a gun?

Will StarLite work as a heat barrier as well as it does with using a flame heat. try using it with a non flame heat like a header wrap or a stove pipe?

i will buy your starlite recipe for 1 trillion dollar. zimbabwe dollar ...... call me if you interested

i think the real differnce between the starlite and the carbonbread is that starlite works some sort of reactive (builds new shielding with the backingsoda)

Sciiiiiiiiiiiiiiieeeeeeeeeeeeennnnnnnnnnnncccccceee Prrrrrrrrrrrrrooooooooooooooooooooooooooooojjjjjjjjjjjjjjjjjjeeeeeeeeeeeecccccccccctttttttttttt!!!!

Could you make a crucible out of Starlite?

厉害！！！

NASA had done the research on the original Starlite material even w/o knowing the exact formula itself - they got the working principle.
So it shouldn't be a surprise that they use Carbon-Carbon foam for the Solar/Thermal-shield for the Parker Solar probe. According to the guys working on the project that shield is taking about 1300 degrees Celsius on the sunny-side :) and lets only 300 reach the back-side.
I guess even better insulation could be reached, with more material, but as all things launched in space. weight is also important factor.

The most common industrial cutting method is Oxy / Acetylene for steel. It would be interesting to see if a few hundred micron (equivalent to primer plus 2 coats of paint) of starlight can prevent or inhibit oxy cutting of steel plate.

So only can handle heat? How about a bullet ?????

Will starlite rot through time or can last indefinitely? if it last long it will be super interesting

Great work, thanks, but do you really have to have this so loud and so annoying music blasting during the tests!!!

You literally copied NightHawkInLight's intro

use Perlite and Sodium Silicate. That should handle heat very well... Sodium Bicarbonate is optional, but worth a try.

Use a real laser 40w Chinese laser will be about 20w. use a real laser 600w to 2kw laser like cutting high carbon steels including diamonds.

This was a very nice experiment! I wish my laser was still working. I have tried replacing the corn starch with flour and the PVA glue with a DIY flour/sugar glue. My initial results are promising. I still used baking soda in every experiment. I'd love to subject my samples to a laser like that. Very informative!

People need to remember that all of the government tests from multiple countries always stated there was almost no visual damage as well as no damage to the material. The only visual damage experienced was from the nuclear bomb tests which left a small burnt mark. So take 10k degrees and have a little bit of this stuff being burnt a little, but still didn't pass through.

Mix thoes two bottles with number 2 let's c what happens

Starlite vs Greek fire.

Strach-lite

I'd be curious about Starlites effect on Cold&its heat disippation capabilities, like if this material disippates heat almost instantly wouldn't it be usefull to use it to cool down surfaces? also what are the insulating properties? COuld it be used to make Fire-proof insulation for homes?

Darth Vader armor.

Being that a laser works by direct friction rather than applying radiant heat, the standard DIY Starlite performed far better than I expected.

Now we know how to defend against laser guns😏

Carbon - a mysterious element

Love your accent man...

Would have been nice to se other comparisons - like metals, plastic, ceramics so as to get a better idea of what actually goes on in this video.

Awesome video and music bro just subscribed

This seems to be perfect to use on leaking exhaust systems and then out a soupcan over it?

It looks like this material can create a lot of graphite foam.
Once you have burned it with the torch,
try to stimulate the burned area with the laser in raster mode.
If you blur it, you get the same area (higher focal point) is bombarded with the laser more times at lower density.
In this case it is not necessary to put much power.

This laser light should stimulate the graphite, to create graphene foam.
That by not creating perfect hexagons, manifests capacitive properties because of the defects it has.

muy bueno saludos de chile

You should've tried longer to see how many 1 min bursts to breach through of it it is truly impenetrable.

Also, the original inventor said "common household materials" but he was a hairdresser right? Maybe what was common for him isn't common for us, some ideas should be tried with what a hairdresser might have at their home.

The guys are selfish prick I'm glad he's gone

Corn starch with water is a non Nutonian fluid it may be the case that constancy of the viscosity, independent of stress, as the difference in temperature creates stress, is the key of that interesting property.

Actually lasers have negative Kelvin temperature. That's why they can heat objects basically infinitely and be used for example to start fusion reactor. Focusing for example sun light, it's not possible to heat object hotter than sun's surface. Thermodynamics laws allow this for lasers because of negative temperature.

What comes to definition of material resisting certain temperature, it needs lots of clarification. Does it mean it's surface temperature can get that hot, or can it resist normal pressured air,heated on such temperature or can it withstand thermal radiation which comes from that temperature.

Plasma in a plasma ball can be several thousands if degree C, but it don't melt or even significantly hear the glass. That's because it's very low pressure.

With starlite, I can pretty much certainly say it can't sustain 10000C surface temperature. No known element or molecule can and it's highly unlikely that such substance exists.

There are many ways which materials can resist high temperatures certain amount of time by sacrificing their material. Basically there need to be a good insulation for example from carbon foam and then cooling from vaporizing substances or endothermic reactions. Vaporizing gases can also reflect or block thermal radiation or laser light.

It is possible to resist intense thermal radiation or laser light infinitely by reflecting them away, but it's not the same as heat resistance.

I know you are a pro at working with materials but I strongly suggest real caution in working with talcum powder. I am not sure that even a very fine mask can fully protect you from that known carcinogen.

Interesting experiments... and nicely documented... but I do have a couple of comments...

1. I suspect that your LASER can deliver MUCH higher temperatures than your estimates (unlike a torch flame it's delivering what amounts to "pure energy", and with foam-like materials, to a material with almost no mass)
2. Note that carbon does BURN in air at high temperatures... and so doesn't hold up to high temperatures for long in the presence of air/oxygen (another video I saw some time ago tested some formulations that "produced a sort of carbon foam with INERT GAS bubbles" - which would protect the carbon from oxygen; this would seem to be a weakness of any formulation with a high percentage of carbon - at least in atmosphere; I would think using some sort of ceramic powder, bonded with glue, might work well - although baking soda is actually quite temperature stable)
3. In order to have commercial applications the material would have to be stable against moisture and some degree of mechanical stress.
4. Note that the absorption spectra of materials with a CO2 LASER is rather different than with other sources of heat (so that would suggest rather different materials to disperse of diffuse rather than absorb the energy from a CO2 LASER than from a flame or frictional heating)

(It seems to me that, with modern materials, some sort of silicone aerogel, with a ceramic coating, would survive extremely well. Alternately, something like a coating of ceramic powder, with a micro-plating of gold on the powder, dusted over a thin layer of heat-conductive metal, would reflect most of the energy at the wavelengths delivered by a CO2 LASER, and would prove almost impossible to heat... but wouldn't necessarily work well at other wavelengths or with direct heat sources like a flame.)
