Get into a sticky situation.
- skim milk
- baking soda
- measuring cup
- measuring spoons
- paper towels
- rubber band
- Check with a grown-up before you begin.
- Did you know you can make glue from vinegar and milk? Here's how.
- Add 2 tablespoons of vinegar to 1/2 cup of skim milk. Stir them together and let the mixture sit for two minutes. The vinegar will make the protein in the milk stick together to form small white lumps called curds. The leftover liquid is called whey.
- Next, you'll need to strain the curds since you won't need the whey to make glue. To make a strainer, put a folded paper towel over an empty cup. Push it down in the center so it forms a bowl shape. Put a rubber band around the top of the cup to hold the paper towel in place. Pour the curds and whey into the cup with the paper towel. The whey will go through the paper towel and the curds will stay on top. Wait about five minutes for the whey to drain through the paper towel.
- Use a spoon to carefully scoop out the curds. Put them between two dry paper towels and press down to get all the whey out.
- Put the curds into another cup, stir in two teaspoons of water and then add one teaspoon of baking soda. The baking soda reacts with the vinegar that's in the curds, producing carbon dioxide. If you hold the mixture up to your ear, you can hear tiny bubbles popping. If this mixture doesn't look like glue, just add some water.
Now it's time for you to get gluey. Test out your new sticky stuff and tell us what you think. Tell us what it can hold and for how long. Can you stick a banana to a paper plate or a penny to a ping-pong ball? Make yourself a Stick-O-Meter to compare the stick factor of this glue with other stuff that sticks.

The glue that I made worked very well. But I had to stir it for 5minutes.

There is another way to make something like glue, all you need is cornstarch and water. use a little less cornstarch than water, then you have GOO

Well it turned out perfect. I compared it to store bought glue and it actually stuck better than what I got from the store. It worked out great!

I had not thought at first that it was the glue that was popping. So I got really amazed by that.

when I found out I needed to do a science experiment, I went here right away. I told my teacher about this and she said that it was perfect, she even told the whole class! when I made my glue, it didnt look like glue, so I added 1 1/2 more teaspoons and it worked! I had alot of fun doing this project! it was so much fun! at first it looked like baby vomet but then it worked like glue. I was surprised that it stuck better than Elmer's glue! after only 3 minutes, the penny with the Elmer's glue slipped off! I was so surprised!

well it really worked and it was really fun to do and it really worked when I put the glue on 2 pieces of paper it really worked so now I won't have to buy glue for like a project or something

it was really cool that it worked
Tiffany, age 11 of VA wrote:
well, when I did this experiment it was so much fun! hearing the bubles pop sounded so cool! then I checked to see if my glue really worked so I put it on my paper and stuck another paper on it and it worked! now I know how to make glue!

It was really fun!!! After making my glue, I tested it and I was surprised to see that the glue was able to stck a penny to a plastic bottle!!! I loved doing it and the result was great too!!!

when I found out I had to do a science experament I went right to this web sight and saw glue so I desided to make it and it worked.

I heard the tiny bubbles fizzing and I liked straining out the whey from the curds. It does look like glue!

I followed the instructions in making the glue and had some good results! I listened to the vinegar reacting with the baking soda and saw that it started to get thicker. I then tested the glue and found that it stuck first of all a coin to a piece of paper, then a leaf to the paper, then a piece of paper to the paper and finally a bottle of nail varnish to the paper - they all stuck really well and I was very surprised that this worked from easily found ingredients in my house!

First we added the milk and the vingar. Next we put a paper towel over a cup and drained the whey, so the curds were left on the top off the paper towel. It took a while to drain through. We mixed the curds up with water, after that we added some baking soda, the mixture started crackling. We kept mixing and it formed little gloopy bits. Our glue stuck cardboard to kitchen roll and a penny to a piece of plastic!!!

In my class we were doing science and we chose to do Make Your Own Glue. We did everything that was in the booklet. It totally worked!!!

I tried the project and it totally worked! I didn't add the right amount of water because I found out that if you do, it comes out real watery. I tried glueing a banana, yoyo, and a pen. None of them came off!!! It was awesome!

When I did it I tryed it on 2 peaces of paper and they got stuck togher! So it actually worked!

I did everything you said but the milk and vinegar didn't turn ito curds. If you put more vinegar does it effect the curds?

My family and I tried to make glue. It worked perfectly. It was such an amazing thing. Now I don't have to go to the store to by glue I can make it.

Well first off I did not have skim milk so I made it with 2% milk with vinagar and baking soda and I strained it out but it didnt stick but I left it for 2 minutes and it just would not stop rising up and up! It was still pretty cool!
