Super Stretchy Slime Recipe
Being able to share my passion for science is one of the many reasons why I love my job. I get to go into local elementary and middle schools and teach them various STEM (Science Technology Engineering and Mathematics) activities, my favorite workshop is LEGO Robotics, mainly because I love building the robots, my next project with the LEGO robots is to build one and program it to solve a Rubik’s cube for me. I find it highly fascinating for something that runs off of human power to solve something that not very many people can solve in the first place.
When you teach STEM, to little kids the best way to go is something they can play with and is easy to do. Yep, that’s right, SLIME!! My coworkers and I love to experiment on different recipes and the one I am going to share today is my absolute favorite recipe. This recipe is great because it doesn’t use any harmful chemicals and if your child acciecentally eats it, no harm willl come to them.
Before I share the recipe, I wanted to give a quick science lesson as to why slime works, why the ingredients mixed together makes a solid object. Slime is defined as a non-Newtonian fluid, now you’re probably thinking, what in the world does that mean? Well, it is actually pretty simple. Issac Newton, one of my favorite scientists, did work with gravity, motion and math but he also worked with fluids. A non-Newtonian fluid is something that behaves like a liquid but is also a solid, so something like slime, it deals with viscosity. I could go on for days about viscosity and these non-Newtonian fluids but that is not the point of this post.
STEM activities are something that I encourage everyone to look into, nothing is better than knowing why and how everything that we use on a daily basis works. Or if you just need to distract your kids from something, these STEM activities are great distractions. I am one of those people that would rather just do fun activities like this all day long, and lucky for me, I get paid to experiment these type of activities.
Since slime is great for many uses, fun and even stress relief, it will be one of my favorite projects. I will share the recipe with you and I encourage you to try it at home, I will provide links that you can buy supplies off of or you can go to your local store, like Walmart but look around your house first because you might be surprised with the items you find.
Super Stretchy Slime Ingredients
Jello Shot Cups– best for when making multiple containers of slime if not just use regular Tupperware
Elmers Glue– I bought a gallon of it because I experiment quite a bit, plus its cheaper
Baking Soda – If you’re like me, I use baking soda for everything so I get the 13.5 pound bag
Contact Solution– since I wear contacts everyday I buy in bulk plus it’s cheaper for me
Food Coloring– In my opinion the gel works better, you can also use paint but food coloring is safer
Popsicle Sticks– again better to buy in bulk because you can use it for different projects
So now that you have all the ingredients, follow these steps and in the end you will have some pretty awesome slime!
1. Fill bottom of Jello Shot Cup with Glue, make sure you cover the bottom completely, don’t go overboard with the glue because too much ad the slime won’t mix properly. No more than a quarter of the cup should have glue
2. Next, take 1 teaspoon of baking soda, keep the baking soda out because there might be a chance that you will need more
3. Mix those two ingredients together, really make sure that they are mixed together and you get all of the glue from the bottom, otherwise your slime will be really sticky and that will be super messy!
4. Now you can choose your color or colors, only put one or two drops of each color. The more you put in the darker your slime will be. If using paint just one drop will do, another option is to add glitter because who doesn’t love glitter slime?
5. Mix that together, make sure, again to get all of the ingredients to mix thouroughly, it should look like the picture below.
6. Finally, add 2-3 drops of contact solution to harden your mixture. Keep mixing and in the end you should have super Stretchy slime. If it has a lot of liquid add less than a half a teaspoon of baking soda (be careful though too much and you might ruin your slime)
7. You should now have super stretchy slime and you can play with it!
