Hard Candy Chemistry! 

Would be watchable if some "artiste" wannabee hadn't been allowed to inflict their ultra-cuteness on it...

Wow. Makes me understand a bit more. I made candy from isomalt but poured it directly into my mold and the next day they look like they are melted.

Thanks now I do actually understand it more!

very nice video!! I really did not know how to make hard candy as yoy did, thank you!!!

I luv how the candy came out the rollers

I want to do this at home!

I guess it would be better if the flavoring is added during the boiling process

What will be the difference, with or without adding corn syrup?

You can also get the color and flavor with Kool Aid powder.

This video is the most UN scientific candy making video I've found. What kind of pan? What kind of thermometer? Ingredient AMOUNTS? I give you a C- Doctor Hartel.

what kind of acid is that?

after it has hardened to the glass state, can it be heated again to soften or melt it?

Thank you Richard. Do you have some website you can recommend where good, but second hand (less expansive) mould machines and probably a small tumbler barrel can be purchased? A lot of people are using silicone moulds lately.... do you think this would avoid having to tumble the candy to get rid of the sharp edges? Also, I have been looking into copper pots... I have read that actually cooking in copper pots that do not have a stainless steel barrier between the cooper and the food is bad... is this true? I must say I agree with other people here... the teeth chomping down on every cut... is quite annoying... Not intended to be a rude comment though!

Why use liquid glucose? I don't know different corn syrup and liquid glucose.

How to make hard candy for last with 2 year expiration date? without melted affect?

Measurements? Social distancing. Good a time as any to try this.

Why does my sugar turn golden color as it’s cooking. I keep it on a low heat but at 160 degrees it starts to turn color?

I hope you can help me, is there anyway I can reserve hard candy and a craft project?

Tumble the candy in powdered sugar (icing sugar).

well citric acid is commonly used in candy making to make it sour, so yea, acid

I want to ask you about making candy....how do you make candy hard? I make a candy of liquid glucose but it is melted.....so can you tell me what do I do to make the candy hard?

🙏🏾Thanks

Nice !!!

What can I use and when to give it more shelf life and stop from melting ?

Can one use sugarcane juice,instead of crystal sugar?

@googolplexbyte Yeah, they should've used SI units.

Please I need this machine.help me sir how should I buy ?

why did you not evenly disperse the flavoring and coloring?

i need your help were can i purchase on line the spray to harden the sugar piece so it dont get sticky please send me the link thank you so much keep up the good work

Is that an induction cook top? If o, I need to cook candy to a hard crack (300 degrees), how would I utilize the induction? It usually takes about an hour to reach 300 degrees so that the water boils out. If the induction unit is cooking faster, how will I know if it has achieved the hard crack needed for hard candy? Thank for your assistance!

Where can I get copper pans like that

Where can these machines be purchased? I've looked all over the web but can seem to find any for sale.

Yummy!!!

Sir what is tha amount to be taken and its ingredients done?

ACID? He said ACID? :O

Whts the ingredients count??

why did you add acid??? Really wanna know that one.

Quick question - would Hollywood effects sugar glass be made this way?

Why acid?

can I get measurements for the ingredients?

Weights or measures of the ingredients ?? Also was that Citric acid ?

Where can I get one of those mold crank

Corn syrup isn't that a product of Corn ?

hello~~~ y my candy still sticky when i finished....

Ingredients please

Once the candy is done, how do you keep them from sticking to each other?

Candy doesn’t make sense fun. Science just makes candy boring.

He added "acid". >.>

He seems nice

i need those gloves.

not scientific at all, didnt explain what the stages are best for, didn't say if it was citric or ascorbic acid, and your candy is way too wet. its gonna be sticky and soft. can already tell by the look of it when it dropped on the sheet tray. a real candy maker rather than some phd would have done a much better job. go watch them.

Cool, but the chomping teeth are very irritating!

which acid is added during cooling

Can you use food coloring?

yum

wat acid is that?

from GTIIT

WTF is Fahrenheit?

Great video, interesting science. The tooth-chomping animation was distracting and annoying, though. Can't win 'em all?

Ok.

amazing a chemist who doesn't give a shit about Stoichiometry, why you didn't tell the maximum amount of water to crystallize?

STOP! You've made 200 times more hard candy than anyone wants to eat!

Ambiguous very unprofessional

chomp! lol

Sound effects are absolutely idiotic.
