Making Homemade Gak

 
Did you play with Gak as a kid?
 
Have you ever made any?
It may be one of the funnest things to see transform into a semi-solid substance.  Just as much fun for me to make it as for my kids to help pour and watch as I mix……
 
……and then squish their little fingers into.
(and much more fun than just buying.)
 

I found this recipe here.
Then gathered all of my supplies.
(I bought the liquid starch at Wal-Mart over by the laundry detergent.)
Mixed the food coloring in with the glue…
Then started adding the liquid starch a little at a time.
Make sure to just add a bit of the starch add a time.  Soon you’ll have to knead the Gak to incorporate more of the starch.  Just keep at it……it’ll work.  (and I didn’t even use all of the starch it called for…..so just see how it goes.)
Then let those little chubby hands test it out.
And figure it all out.
 
And play and giggle their little hearts out.

    That looks like a great project for my kids, but what is liquid starch and where do you find it?

    Ashley says:

    Rebekah, I bought the starch at Wal-Mart in the laundry detergent aisle. It was next to the static cling and scotch guard type stuff, way down on the bottom shelf.

    Good luck!

    Thanks for sharing this recipe. I always made "GOOP" using powdered starch, but I cannot find powdered starch anymore. I have taught Kindergarten Sunday School for over 20 years & I always make GOOP at the beginning of the new year. I was so sad that I wouldn't have it anymore. I hope this will turn out similar – I can't wait to try it. We also "paint" with liquid starch using 1 inch squares of tissue paper.

      I make goop for the special needs children I work with all the time, I use water and cornstarch. It is a little different in consistency but the same principal. It is hard to the touch but then gets gooey and runny when you try to pick it up. You can also use food coloring to make it fun colors. Always a hit with the kids!

    I have made this but using Borax. I love it because it does not make a mess like playdogh does. Its easy to clean up (just dont get it in your carpet). my kids like to put a straw in it fold it over wait for a few seconds for it to seal itself then blow huge bubbles.

    Ashley says:

    Yes, it can stain because it has food dye in it. And the gak stuff can get stuck in fabric if smooshed into it. But it doesn't come off on their hands. I only let the kids play with it at the table….and stay around while they're playing with it. But it sure is a lot of fun….even for me to sit and play with. It's just a gooky, smooth, rubbery, ball of fun.

    My son made something this at Science Central when he was young and it was around Dr. Seuss's birthday and they called it Oooblek.

    If you have kids and have never tried it I highly recommend and I love the pictured step by step tutorial that will make it easy for younger kids to understand – they get so much more excited when they "make it all by themselves" then have to have Mom or teacher intrepret the instructions for them.

    Thanks for sharing this with all of us!

    I'm a preschool teacher and we've made this a couple times, but please be careful. It can get stuck on clothing and we had a little girl who got it stuck in her hair and the only way to get it out was to give her an impromptu and very uneven haircut. Just make sure you use with supervision if you have little ones.

    As I posted on stumble, this is actually ooblic. Gak is different and can also be made easily with different household things (borax, water, and elmer's glue). http://www.ehow.com/how_4987667_make-gak-borax.html tells you how. ooblic is more liquid, turning solid in motion while gak is more solid and a bit bouncy.

    I love that this doesn’t use Borax, since I’ve always avoided the gak recipes with that in it (it’s toxic, after all!). The color is fabulous too. :)

      Shannon says:

      Check out the website I found on whether Borax is safe or not. Borax is not boric acid (unlike what many sources say).

      http://www.crunchybetty.com/getting-to-the-bottom-of-borax-is-it-safe-or-not

      • 46.1.1

        Actually, she’s got some misinformation there.

        For instance, she says:
        “Borax is not boric acid.
        That’s where the majority of the online confusion appears. With no surprise; at least half of the studies I’ve found and citations I’ve read have listed their testing matter as “either sodium borate or boric acid.”
        The difference between the two is: Boric acid is produced when borax is reacted with another acid (like sulfuric or hydrochloric acid). The result is an acid structure (pH of 5.0), rather than alkaline, as borax is (9.3 pH). (I’m not going to get into the “is boric acid safe or not” question here, because that’s a whole ‘nother can of worms.)”

        This is technically true, but if you look at the MSDS for 20 Mule Team (borax) it says:

        “Nonetheless, the following effects have been reported for a component, sodium borate, and boric acid. Sodium borate upon entry into the body becomes boric acid.”

        REPEATED, from the company’s own MSDS:

        “Sodium borate upon entry into the body becomes boric acid.”

        So if it’s ingested, it becomes boric acid (we have acids in our body too!).

        In addition, even the MSDS she quotes acknowledges that borax and boric acid are the same:
        Chemical Name: Boric Acid Disodium Salt

        The MSDS says there is NO information on safety regarding:
        CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available.

        So them classifying it as level one is not very reassuring! There have also been some studies linking it to reproductive issues and fertility problems, along with birth defects (especially of the male reproductive organs).

        Note that the MSDS does acknowledge:

        Special Remarks on Chronic Effects on Humans: May cause adverse reproductive effects.
        Special Remarks on other Toxic Effects on Humans:
        Acute Potential Health Effects: Skin: Dust causes skin irritation. Poorly absorbed through intact skin. Eyes: Dust causes eye irritation. Inhalation: Causes respiratory tract irritation. Ingestion: Acute toxic effects of borates in general are nausea, vomiting, diarrhea, and delayed skin redness, rash, and dizziness. Chronic Potential Health Effects: Chronic exposures can produce eye irritation, coughing, and skin rash (the latter following ingestion).

        She points out that borax is “only” classified as level 1 for health problems, but I think she may misunderstand the rating system. Level 4 can kill you immediately. Level 3 can cause permanent disability if you interact with it. Level 2 substances can cause lingering injuries or “temporary incapacity.” Level 1 can cause “significant irritation.” Yes, that’s better than death, but do you want to give a small child something to play with that contains a natural pesticide that can cause “significant irritation”? Safe materials are level 0.

        The company itself acknowledges that borax is hazardous:
        “Based on our hazard evaluation, the following chemical substance(s) in this product have been identified as hazardous.
        INGREDIENT
        Sodium Tetraborate Decahydrate”

        I wrote about borax on my website years ago (http://magicalchildhood.com/articles/borax.htm) and I continue to get angry letters from people who are upset that I advise against putting borax in children’s craft recipes. People get really worked up in these letters, and it confounds me.

        I don’t understand why people are so intent on proving that it’s safe to use borax around children. It does absolutely no harm to avoid it, especially in craft recipes. :)

    MiracleMommy says:

    Using laundry starch as an alternative to borax is not safer. One of the primary ingredients of Stay-Flo Laundry Starch is, in fact, borax (sodium tetraborate). In addition, there are several other toxic ingredients. Don’t be fooled by the benign name of “starch.”

    You would actually be better off using straight borax rather than having the addition of a few other toxic ingredients. Actually, borax is not as toxic as some people thinks, as there are several blogs and websites around the internet that have confused boric acid (extremely toxic) with borax. If you do a bit of deeper Googling, you can find out more information. The dangers of poisoning from small amounts, risks of infertility and dangers to unborn children all refer to boric acid, not borax, but so many people have misunderstood that and put it out as the dangers of borax. You can also check the 20 Mule Team Borax MSDS (Material Safety Data Sheets). Borax, though related to boric acid, is quite different in chemical make up, and must be ingested in large quantities to do any harm, and even though it typically only causes “gastrointestinal distress.” However, it is still advisable to keep it out of reach of children and away from food.

    Either way, once you have made slime/flubber/gak/goop/putty or whatever name you want to call it, the borax is no longer in its original form. It combines with the polyvinyl alcohol in the glue and forms a polymer chain — it turns into a plastic. This is a chemical reaction. A chemical reaction means that the different items have combined and turned into something completely new and different. Now you no longer have glue or borax, you have now made your very own plastic.

    I taught Environmental Science/Environmental Education for ten years. and made slime tens of thousands of times to teach chemical reactions and the nature of plastics. Yes, that many, as I worked with about 6,000 students per year.

    The way I did it was to make up gallons of borax and water solution, along with glue and water solutions, and put them in bottles with pumps. I could then have the students put a pump full of each solution into a zip close plastic baggie, and then knead and squish the baggy until the slime formed, at which time they could remove it from the baggie to continue forming it and playing with it.

    Now, no longer borax or glue, they have a relatively safe product that doesn’t irritate skin with minimal contact with the borax.

    On a side note, FWIW, I battled infertility for twenty years, but become pregnant at a late age (unexpectedly) when I was teaching Enviro Ed and handling borax every day :)

    Suvmome says:

    We just made this….soooo fun and easy. We mixed the water and glue together, added the food color and lots of fine glitter and then the liquid starch (all at once, didn’t add a little at a time) and then stirred a few minutes. Then my 9 & 7 year olds mixed it by hand until the consistency was less sticky and we were able to handle without it sticking to our fingers. I purchased little plastic “dixie cups” and filled each cup about 3/4 full and then held upside down and squished the goo by pushing our fingers up toward the bottom of the cup. It makes fun “bodily function” noises. We called it a “farty party”. I know…GROSS…but we all laughed hysterically and had a great time. :)
