How to Make Rubbery Slime What Happens When you Mix Borax with Glue?

We had a group come in to make this with some of the kids I work with.  It was a big hit.  They called it slime but I found it to have more of a rubbery feel.  The kids ages 5-9 had such a good time making it, I decided to try it at home with my little one.  Sure enough she loved it too.  Since Winter is coming and my daughter is still an Elsa fan we decided to go with a frozen theme foam slime.  So instead of using white Elmer’s school glue we used Elmer’s blue glitter glue. We also used a blue gel shaving cream instead of white shaving cream and we added a lot of blue glitter.  Which ever school glue or shaving cream you use the recipe will come out the same.  It’s a fun experiment to try with a class, day care or something easy to do with your child or when you have a play date. This is also a great young student science experiment to do for school. Follow the step-by-step directions below to make your very own rubbery slime.

Materials: Elmer’s glitter glue or regular glue, gel shaving cream (you can also use foam shaving cream), Borax (3 spoonful’s), t spoon of water, bowl (I would use a Styrofoam bowl or a bowl you can throw away) optional glitter

Step 1: Pour 1/4 of the bottle of Elmer’s glue into your bowl.




Step 2: Spray a little of the gel shaving cream into the bowl.  Mix together with the glue, the substance should be a little fluffy.  If it’s not add more shaving cream.  See picture below.





Step 3: Add a t spoon of water and mix together.

Step 4: If you would like to have some sparkle in your foam slime, add some glitter or you can add a lot like we did.

Step 5: Mix 3 cereal spoonful’s of Borax with a cup of water.  Slowly add the some of the Borax and water mixture into your glue and shaving cream mixture.  You will see that a change is taking place.  The more Borax solution you add the less slimy it will get.




Why Does this Happen?

Glue has these long flexible molecules called polymers.  In liquid form these polymers slide past each other quickly.  When borax is mixed with water the solution forms borate ion. The borate ions help link the polymer molecules to each other.  When the borax solution is added to the glue solution the polymers cannot move quickly causing them to become rubbery becoming the slime.

How to make a Volcano out of a Lemon. Summer Science Experiments for Kids

This volcano science project is fun and easy for children of all ages.  Not only do you get to turn a lemon into a volcano and watch it erupt, you learn what happens when you mix an acid (lemon) with a base (baking soda).  Remember this experiment is messy, which kids love however make sure you cover your work space.  Follow the step-by-step directions below to make your very own lemon volcano and remember to have fun!

Click here to learn more about what happens when you mix and acid and a base.


Materials: paper plate, lemon, knife (adult use only), food coloring (1 color), dish soap, spoon, basking soda


Step 1: Have the adult cut the bottom of the lemon slightly so that it can stand upright.  Don’t cut too deep or the juices will come out.






Step 2: Have the adult cut the top of the lemon off (cut a littler deeper so you can squeeze the juice out)







Step 3:  Have the kids squeeze the juice out into a small bowl.






Step 4: Using the spoon, mix the inside of the lemon, so additional juice comes out and there is space to add the other ingredients.


Step 5: Add a couple of drops of food coloring.






Step 6: Add a small amount of dish soap (this will make the eruption more bubbly).

Step 7: Pour the lemon juice back into the lemon.









Step 8: Add a spoonful of baking soda and watch your volcano erupt (it will happen immediately).  To get a bigger eruption you can have the children mix inside the lemon.


v1v6 How does this happen?   The baking soda is a base and the lemon is the acid.  When they are combined they let out carbon dioxide which create the fizzing bubbles.







I also did this experiment adding the baking soda before the juice and it looked like this:




You can do the experiments both ways and see which way gives you a bigger eruption.

How to Turn Milk into Glue Fun Science Experiment for Kids

We can drink milk, pour it into our cereal and use it for many recipes, but have you ever thought you can use it as glue? Now you can turn milk into glue with these two fun science experiments. Try them both to find out which one makes a better glue. Follow the step-by-step directions below to make your very own milk glue

Items needed:

1 1/2 cup milk

3 teaspoons of white vinegar

baking soda





Step 1: Pour your 1 1/2 cups of milk into the pan  over medium heat.  Let the milk heat up until it is warm (never leave children unattended while using the stove).

Step 2: Once the milk is warm add the 3 teaspoons of white vinegar.

Step 3: Over low to medium heat stir the mixture.  You will see milk lumps or curds start to appear.  This happens when the liquid and solids start to separate.

Step 4: Once you have a lot of lumps strain the liquid using a strainer.

Step 5: You should be able to mold the lumps into a ball.  It will be slimy.

Step 6: Put the lump back into the pan.  Add a tablespoon of baking soda and a small amount of water.

Step 7: Stir and heat the mixture on medium heat until it starts to bubble.

Step 8: Once the mixture bubbles remove it from the heat and let it cool.

Step 9: It should look like a thick paste, it not continue to add baking soda and water until it is a paste consistency.

Step 10: Try using it as glue.


How did this happen?  When you added the vinegar to the milk it caused a chemical reaction.  The milk separated into two parts the liquid and the solid (the milk lumps or curds) The curds or lumps are the milk protein called casein.  Casein is a long molecule that bends like plastic forming a natural glue. When you added the baking soda (a base) to the vinegar (acid) another chemical reaction took place.  The bubbles that you saw when the mixture was heating was the carbon dioxide giving off as part of the chemical reaction turning the milk lumps or curds into a sticky, paste glue.


No heat way to try this experiment

Items needed:

1/2 cup milk

2 teaspoons white vinegar

1/4 teaspoon baking soda

coffee filter

2 tall cups



rubber band


Step 1: Pour 1/2 cup of milk into one cup.

Step 2: Add 2 teaspoons of white vinegar to the milk and stir.

Step 3: Put the coffee filter loosely over the second cup and secure it with a rubber band. The coffee filter should be drooping a little in the center.

Step 4: Slowly pour the milk and white vinegar mixture over the coffee filter.

Step 5:  Let the liquid drip through the coffee filter.  This takes a while I actually let the mixture drip for about an hour so It was all out.

Step 6:  Once all the liquid is gone scrape off the milk lumps.

Step 7: Place the milk lumps (curds) into a bowl then add 1/4 teaspoon of baking soda. Mix well

Step 8:  The mixture should become sticky and paste like.  Try using it as glue.

Where you able to get glue from these experiments?  Which experiment worked?  Try changing the amount of milk or baking soda what happens?  Try using whole, 2% and 1% milk which one made the best glue?





Does Air Take Up Space? Fun Science Fair Project for Kids

Does air take up space?  Find out by doing this fun and easy experiment below.  It is perfect for children grade 1st-4th


Materials: Paper towel, tall drinking glass, a pitcher or bowl of water (The pitcher or bowl of water must be taller than the glass)

Step 1: Crumble up the piece of paper towel.  Place the crumbled up paper towel into the glass.  Push down so the paper towel is at the bottom of the glass.

Step 2: Turn the glass upside down. Make sure that the paper towel doesn’t come out.  If it does put it back in and push it down.

Step 3: Quickly place the glass upside down in the picture or bowl of water so the entire glass is under water.

Step 4: Quickly take the glass out of water.

Step 5: Turn the glass over and take the paper towel out.  Is it dry?

The answer should be…Yes!


Air does take up space!  The glass was filled up with air.  So when it was placed upside down in the water, the water could not fill in the glass because the air was already in there.  The air in the glass creates pressure, that pressure was greater than the water pressure trying to get in.  Want to try something else?  After you put the glass in the water tilt it a little.  You will see bubbles.  These bubbles are caused by the air exiting the glass and the water going in.
