Make Hot Ice From Vinegar and Baking Soda
Oct 18, · Amazing Science Experiments with Home ScienceIn this video you will see how to make hot ice at home. Sodium acetate or hot ice is an amazing chemical you can. Jan 16, · Making hot ice isn’t difficult, but if you don’t follow the steps correctly, your project will be messed up and you will have to start over. You want to get it right the first time because this experiment takes MASSIVE amounts of vinegar. What you’ll need to make hot ice.
Combine baking soda and vinegar to make sodium acetate, or hot ice! It crystalizes instantly when you pour it, allowing you to create a tower of crystals. Science is so cool! Making hot ice is a simple process, and you probably have everything you need on hand. Step 1: Combine 4 cups of vinegar and 4 tablespoons of baking soda in a pot. Before we did this experiment, I read instructions for hot ice on a few different websites.
I decided to use the amounts given on Playdough to Plato. Step 2: You have now made sodium acetate! As well as carbon dioxide — it was given off in the reaction, which created all that fizzing. Cook your solution over low to medium heat for about an hour. You want to reduce it down to 1 cup or less. Now, the stuff I how to make hot ice online said that crystals would start to form around how to make hot ice edge of the pan. Well, our solution never formed crystals while it was cooking.
Step 3: Pour your sodium acetate into a glass container and put it in the refrigerator for 30 to 45 minutes. We did this, and while it was in the refrigerator, I scraped some of the dried solution off the sides of the pot, hoping that it would work as the crystals needed to start the reaction. But, this experiment is very forgiving!
I left the solution on the counter and came back to it the next day. And we what does rhubarb look like growing never seen any crystals form in the pan. As soon as I poured the solution out of the pan and into a glass jar, the remaining liquid in the bottom of the pan crystallized instantly!
So I knew we were getting somewhere! Step 4: Pour the cooled solution onto a few crystals that you scraped from the pan. It was so fun to watch! By the end, Aidan was pouring just a drop at a time, and we could actually watch each drop piling up on top of the tower of hot ice.
The sodium acetate solution contains water. We reduced the amount of water in the solution by boiling it, but there is still water in there. The water molecules keep the sodium acetate from forming crystals. Well, crystals may start to form, but as a few 2 out of 100 is what percent join together, the water molecules pull them apart again.
When we cooled the solution, we were able to bring the sodium acetate down to a temperature lower than the point at which it would normally become a solid. This word for this is supercooled. For example, copper remains a solid until it reaches 1, degrees Fahrenheit! Back to the sodium acetate… The crystals in the tray provided a starting point for crystals to grow in the solution, called a nucleation site.
This gave the sodium acetate the push it needed to crystallize! The directions on Instructables said to filter the solution to get rid of any impurities that might inhibit the how to mineral wash jeans process.
The crystallization process gives off heat, so the hot ice is hot to the touch! Not hot enough to burn, though. We all had fun touching it! Our tower was pretty flimsy and broke quickly, but we had a great time with this science experiment. If you want to repeat the process, you can melt the crystals down into a liquid again, cool it again, and make another tower! Also, I was a little worried about our pot, but it was super easy to clean. The sodium acetate dissolves easily and rinses right off.

Thank-you for detailing everything, even the difficulties. I feel very confident going into this experiment. And since I just found your site I look forward to perusing the rest of your site. Hi Sarayou are amazingwonderfulli have a chemistry graduatebut you can simplify science to kids its perfect i 'm following your site ,and pass what you did to my grandsonmy daughter follow the homeschooling with the kids and i know how the effort and responsibilitybut she was happy as she add one day a week for free activities, go on and good luck.
Hi Sara, I am a science relief teacher from Australia and was wondering if you can make the solution at home, carry it to school in a cooler bag, pop it in the fridge at school to use with different classes? Hmmm, now that's a good question! You can definitely make the solution ahead of time. What I don't know is whether you would need to heat it at school for a few minutes, then cool it to get it to the supercooled state. You might want to test it out first! Did you try it. Did it work? You'll have to refreeze in.
If that doesn't work, Reboil it back onto liquid, 5hen refreeze. That should do it. Heat it at before school and let it come to room temperature. It will work that way. A microwave or hotplate will work to heat it. Thank you for sharing! I plan to make this with my grandson today, would you happen to know if any type of vinegar can be used? Seems all I have on hand is red wine vinegar? Ahhh, what do I keep doing wrong? We have had 3 goes at this and the coolest thing I can do is make it freeze in the bowl as soon as I "disturb" it.
Which is actually quite cool and my boys love it but we can't get it to the state of being able to pour it and watch it freeze! Add a little more water if it does this and it should become a solution. You may have to heat it a little.
This was so awesome, I love watching kids get involved in things like this, great kids and I love seeing parents that are spending time with there kids to teach them things like this. Keep learning kids science is so awesome. This was very impressive. Thanks, Pamela. Thanks for sharing this and the science behind it! It really helped explain the process. My 5th grader would like to try to do the boil-ahead idea and bring it to school after - I'd also love to hear if that worked for anyone.
By the way, I've assumed that this is the same process as what's in those "heat packs" sold for health needs and such - but they activate with a click of how to make hot ice metal disk. Any idea what that disk is?? It took me 5 attempts to get this right but once I did, WOW! It is so exciting to see those crystals form :. What did you change to make yours work? Thx Sam. I wasn't able to get this to work. Our solution turned slightly brownish as it simmered and we were not able to get it to freeze to the crystals we got off the bottom of the pan.
Did the vinegar and baking soda dissolve together? We tried it and it was a bunch of mush and didn't even pour. Are we supposed to stir as it cooks? Yes, but The supercooled state of the liquid seems to be important for forming the crystals.
I would definitely test it first before taking it to school! Very interesting! I'm hoping to use it in the 'still solution state' for the making of a mordant for fabric long story. My Boys and I tried this today. We had to boil a second time to get Crystals.
After cooling the liquid when we went to pour crystals formed instantly in the jar, then all of The solution crystallized before we could add it to the plate! Still cool! This one didn't work for us. The solution turned into a sludgy consistency when we put it into the fridge. Any idea where we might have gone wrong?
I'd love to try it again. And thank you for including your process- super helpful!
How to Make HOT Ice!
Making hot ice is a simple process, and you probably have everything you need on hand. You’ll need a couple of hours, though, so keep that in mind. Step 1: Combine 4 cups of vinegar and 4 tablespoons of baking soda in a pot. Before we did this experiment, I read instructions for hot ice on a . Hot Ice: Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic . Jan 29, · In this video, I am going to show you how to make hot ice. It is simple, is simple and easy to do and is lots of fun. I hope you guys enjoy the video, please.
Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice.
If you don't add the baking soda slowly, you'll essentially get a baking soda and vinegar volcano, which would overflow your container. You've made the sodium acetate, but it is too dilute to be very useful, so you need to remove most of the water. Here is the reaction between the baking soda and vinegar to produce the sodium acetate:.
Since the reaction itself produces water as a byproduct there is no need to add water but if the content get thicken add 2 ml water. Once you remove the sodium acetate solution from heat, immediately cover it to prevent any further evaporation. The sodium acetate will crystallize within seconds, working outward from where you agitated the solution.
I was already doing an experiment with my Grade 2 and 4 students using the vinegar and baking soda to demonstrate irreversible change. Now I'll keep the solution and heat it so I can wow them with hot ice. Love it and they will too! We are talking of ml of vinegar. You tell us to add 2 two ml of water if the contents get thick.
Or it is another number that needs editing? Reply 3 years ago. Before putting up this instructable I had made 2 attempts to bring out this result so the first thing I noticed was that Around about ml is left behind after hearing it up And yes the last picture is of the solution taken out from the refrigerator Typo errors Thanks for letting me know The outcome of this exp was my 3rd attempt so maybe I have commited some errors in my instryctable and I will make sure to correct it.
My solution grew a white crust over the whole surface when there was still ml left. Did I do something wrong? I added a bit of water, and am trying now again. Yes you have to remove most of the water And yes formation of white crust means that you were proceeding correctly. Please note that this procedure can be extremely dangerous, with injury potentials due to extreme pressure and extreme cold.
Releasing pressurized carbon dioxide gas into atmospheric pressure yields the CO2 into it's solid form. Get a bottle of industrial CO2 the kind used for soda pop machines. Secure a nylon stocking over the valve outlet and slowly release the gas into the stocking.
Dry ice crystals will begin to form on the stocking. Continue until desired amount of dry ice is captured. Dry ice is made with botttled carbon dioxide gas. Search on youtube for videos on how to make dry ice. Its not cheap..
If you inserted a rod with a couple of RGB LEDs on the end ito the solution, It would be neat to see if that crystal dandelion would glow different colors Is there a specific purpose, you ask? They used to sell these as hand warmers. They were thick, well sealed plastic pouches, with the sodium acetate solution and a metal "activation disk" inside. You "snapped" the flexible disk to start the hot ice reaction.
To recharge, you put the pouches in boiling water, until the ice re-liquefied. What a great teaching aid for showcasing that latent heat is given off by liquids, when they freeze yes, even water. Great instructable. Introduction: Hot Ice. By kirthik vasan Follow. More by the author:. About: I am an undergraduate student pursuing B. I am passionate about creating new stuffs using technology and hungry to learn more and more. More About kirthik vasan ». I am using a ml measuring cup.
Transfer this vinegar into a vessel. The baking soda and vinegar react to form sodium acetate and carbon dioxide gas. Heat the mixture and stir constantly for some time. Set the soultion to cool down and left unagitted. Pour the solution into a separate container. I covered the container with foil paper. Remove the solution from the refrigerator after cooling the solution for 30 minutes. Insert any foreign object which would agitate the solution. Did you make this project?
