Thank you!!

She's too cute to be a chemistry teacher. I'd be too distracted to pay attention to chemistry.

And I love her pronunciation of water, not meant in a disrespect hurtful manner but a "I legitimately enjoyed hearing it" manner. I'm from Michigan and would not dream of making fun of anyone's accent as ours is ridiculous. I mean we call soda "pop" and think euchre is a "fun" card game.

So I have learned.

Yeah whoever edits these videos does such an amazing job, it’s really world class! Can’t give enough props to whoever that is!! 🫠

Yeah,Duck Bumps😊

@@Trav_is_Newman , yea, I see how it is. :)

Does the sound of cotton in medicine bottles trigger it for you? I know someone that has this phobia.

She sounded a little drunk to me also

haha...Close...NJ!

Honestly....not even a little bit.

I literally paused the video and rewound when I heard wooder.

​@@rob9176looked high AF, like just smoked with Snoop high!

The cover they did became a hit song to be precise ;-)

Mine was 1980, same reactions (pun intended) and conclusion!

@@steveh8724 I like your retort. Thanks.

So you say

Wonderful! Thank you 🧪💜🧪

Thank you!

Thanks!

I used to hear this pronunciation when visiting Pennsylvania.

Thank you for watching!! And the same to you!

Yes, any vinegar with a higher concentration (greater percentage) of acetic acid would require less to be add which reduces the amount of time needed to evaporate any excess water. And yes, there are much more cost effective sources of alcohol that will also work. I always try to use the ethanol because it does burn a little cleaner. Some rubbing alcohols are made with denatured methanol or ethanol and are much less expensive. I just couldn't find any at my local stores currently.

Remember the fumes from some alcohols may be toxic

@@dauman1442 Nope.

Wonderful! Thank you!

Same for me, although my daughter is currently only 6 months old 😛(so she won't be doing any experiments like this with daddy for some years, of course)

Thanks!

Ironically she hates that show lol

Thank you!

Thank you for watching!

Only two? I’ve gotten four although this is the first I’ve watched

Thank you! Hopefully, for everyone's sake...it just stays as cool chemistry to know.

That is accurate 👍

Yes it would!

@@ChemCampwithMrsNewmanwould I be able to dissolves a salt throughout the gel so the flame is always coloured or would that change the chemical reaction?

You should be able to mix it in once the gel forms. You probably can even just sprinkle in over the top before igniting the gel too.

Wow, thank you!!

Dow Corning sold the brand name but included a poison pill so you can easily tell the difference between the old borosilicate glass and the new cheap stuff. Upper case "PYREX" is the legacy good stuff. Lower case "pyrex" is NOT.

Good to know. Gotta gave Pyrex for experimenting 👍

@@ralphwaters8905Thank you for the info, explains why my new Pyrex measuring cup broke heating up water in the microwave!

​@@ralphwaters8905american houshold pyrex have never been borosilica. Labware pyrex are always borosilica through

@@aggese - "Never" is a pretty broad statement. Check out en.wikipedia.org/wiki/Borosilicate_glass

Yes it is 🏕️ Thank you for watching!

Thank you!!

You're welcome! And thank you!

Thank you!

Thank you! Glad you learned something new & enjoyed.

Have fun and be safe! Thank you for watching!

Thank you very much!

Thank you!!

Thank you!

Wow, thanks!

Excellent observation skills! I am from NJ. Thank you!

Thank you!

And thank you too!

Thank you too!!

Thank you for watching!! And I'm just east of Philly in NJ.

I never heard her accent before either. It does not sound very "Philly" to me. Maybe I am confusing "Philly Ghetto" for Philly metro accents. But sure is a unique accent. Being a Central Midwestern, I have no accent. We are the only English speaking culture on earth that actually pronounces words phonetically correctly.

Hope you enjoy! Be safe.

Hi yes I did try it and it worked just great thank you for the tip god bless

Thanks for the advice! I wasn't wearing a mic so we will have to figure out the issue.

Thank you!

Yes. If you can find a vinegar solution with a higher percentage of acetic acid you will need less of it (the smell will be much more potent though). Ethanol is a much safer alcohol to work with and this is why I prefer using it. Some rubbing alcohols are actually made with denatured ethanol and are much cheaper. Unfortunately, I have not been able to find any locally lately and that is the only reason I used the ethanol.

Thank you! I'm not certain about lifespan/storage life. Usually I would make these with students in lab and we would use them to make s'mores to learn about limiting reactants. So we would use them right away. If you are going to store it for a period of time I would be sure to use an air tight container to prevent any evaporation of the alcohol.

Thank you! Great point. I tried to make that clear by stating to continue with chemistry instead of food. I'll endeavor to be more obvious with my precautions in the future. I appreciate the input!

Thank you!!

haha...thank you! My mom actually got it for me.

Thank you!

haha...very glad you got a good laugh. I'm a little south of Boston though. NJ.

Awesome! I hope you enjoy trying it out. Also, you will need a filter of some type (even just a paper coffee filter) if you are using eggshells. Only the calcium carbonate will dissolve so you will need to remove the other stuff prior to heating to drive off the excess water.

Using isopropyl alcohol will also work. Ethanol just burns the cleanest and safest which is why I prefer to work with it. Denatured ethanol is also inexpensive, I just wasn't able to find any locally.

Glad you liked it! Thank you!!

Chemistry makes me happy!

Not gonna lie…I’ve been waiting a while for someone to give that one some love! 🫶😂

Thank you! Close...NJ. What possibly could've given it away?

@ChemCampwithMrsNewman Wooder instead of Water. I still say it that way after moving to the Harrisburg area 12 years ago. Side note: The Philly pronunciation of water gave the FBI profiler the procedural idea to investigate and catch the Unibomber. That's why we should embrace it.

It’s actually spelled “wooder”, check your facts! W love from new jersey 😂 thanks for watching 🙏

Yes, I apparently pronounce it a little funny. Who knew!

Yes, once the gel is ignited, only the alcohol is burning. But instead of being able to move freely it is contained within the gel. Which makes it much safer to burn. Alcohols have extremely low viscosities, so if they spill they spread very quickly which is a major problem if it is already burning. I also believe being contained in the gel allows for an extended burn time. This is simply the chemistry behind what is found inside a can of Sterno which has the ability to burn safely for hours and is very popular for heating food at catered events.

Calcium sulfate in chalk won’t dissolve/react being the salt of a strong acid being mixed with a weak acid-so creating sulfuric acid is not a favorable reaction. The calcium sulfate should remain insoluble. You should just be able to decant (with enough time) or filter any calcium sulfate off before concentrating the calcium acetate if better purity desired.

In preparing for this video, my wife actually ran several trials and finally found something that worked well for her so yeah make sure it’s the right stuff

Some chalks do, especially if they are sidewalk chalks. Old fashion white chalkboard chalk however, should be calcium carbonate. At least Crayola's seems to be.

@@ChemCampwithMrsNewman I had tried commenting, and asking a question - a week or so ago; only to find that my comment/question was not at all visible when checking while logged out of youtube. When logged in: my comment/question was cut by about 50%. Crazy..... Anyway, I'll try again: Can the boiling down process be avoided by using 10% (acetic acid) - by using a diluted amount of "Harris" 30% vinegar?

Some bottles of rubbing alcohol are made with denatured ethanol at much more friendly price point. I was not able to find any at any of my local store and I do prefer using ethanol to the others.

Because it dries your skin out really bad. But I didn't know it was unsafe to touch, more like, "Overly-CYA legal warning on a not-really-dangerous" substance. Of course, if it's burning at the time, the gel will stick to you and continue burning, and while it's a neat party trick to put alcohol on your hand and light it up, burning alcohol gel gets really hot.

Interesting, thanks! Roughly how many % of the total heating energy does the calcium acetate account for?

I haven't really stored it before. We usually make it in lab and use it to learn about limiting reactants. I think it can be, as long as it is in an extremely air tight container to prevent evaporation of the alcohol.

If you are going to cook directly over the flame, I would be sure to use ethanol because it burns the cleanest and shouldn't have any affect on the taste. If you are heating the food in pan over the flame then methanol is safe to use (even some of the Sterno products list methanol as an ingredient). If you have real sensitive skin, touching the gel might cause a slight irritation. But with all chemicals it is best to try to limit exposure and be sure to wash your hands thoroughly after use.

If you use high alcohol content, like 99% rubbing alcohol, it will burn very clean.

I'm thinking that would work just fine, although I'm also thinking you're going to really smell the acid.

​@@MMuraseofSandvich Yes, you would want to do this in a well ventilated area, and with eye protection. 30% acetic acid is serious stuff, and needs to be handled in a safe manner. This would save a lot of time boiling the mixture down to reduce the water content. Seeing that you boiled the 5% vinegar mixture down around 50% of its original volume, and 30% vinegar is 6x more concentrated, I wonder if you totally eliminate the need to boil down the mixture using the 30% vinegar - you would be introducing less than 1/6 the volume of water, since you could reduce the amount of vinegar required for the reaction to 35ml, instead of the 200ml required using 5% vinegar.

Yes, 30% vinegar should do exactly this if you have it available. I just had 5%. And it does require the extra safety precautions. Hope it works well for you!

@@ChemCampwithMrsNewman It would be much appreciated if you could do an update video using the 30% vinegar, and see if this would eliminate the need to boil down the mixture. This would save a lot of time and energy if it works that way. You may still need to add some water with the 30%, because it may be too strong - there does need to be some water left over for the entire process to work. As far as obtaining the 30% vinegar, this is a very common item in Home Depot and hardware stores, because it is commonly used for heavy duty cleaning, so it is readily available.

I wish I could tell you. I tried a few different ways and none work. I'm beginning to think that this is bs. I've seen several videos before this one so I'm not singling out this one. This one evaporated the water after adding the calcium unlike the others so I will try that. I have gotten a tiny amount but to get enough to fill one can, it would be much cheaper and far less time consuming to go buy a case of them.

Did you add wudder?

Honestly, it took me a few days of trying this experiment to get it to work prior to filming the video (it really irked me that I couldn't figure it out so I kept trying). I found that using the correct the ratio of calcium carbonate to vinegar to be critical. If you are using 25 grams of calcium carbonate and 5% acetic acid (household vinegar) you will need to add at least 500 ml of vinegar to react completely. The solution should go clear when all of the calcium carbonate has reacted. Then heating gently to drive of the water and to create the saturated calcium acetate solution will take a lot of time due to the volume of vinegar used. The solution should become cloudy again when you've driven off enough of the water. If the solution has too much water remaining it won't form the gel. You may also need to increase the amount of alcohol used because you've started with a lot more of the calcium carbonate. Hope this helps!

Apparently that is how I pronounce H2O. Didn't even realize until this video.

I found the ratios for this have to be just so. The heating becomes important in creating a saturated solution of the calcium acetate. If there is too much water left it will not form a gel with the alcohol.
