Criteria Used in Evaluation of the Best Slime-Making Kits

While making this list, we discovered that there is a whole lot more to slime than meets the eye. This gooey substance is also a way for kids to get creative and to learn more about science. While creating this list of the best slime kits on the market, we wanted to highlight not just the advantages of using one of these slime toys but also the benefits of slime itself. Following are some of the main advantages of making and playing with slime.


Sensory stimulation is perhaps one of the main benefits that a kid will experience while playing with slime or making slime from the slime-making kit. It turns out that slime is a substance that will engage all the senses of the body, except for the taste of course. A kid will be able to see the bright colors of the substance, they will be able to touch it and experience how sticky it is. They will hear it glop around at times while playing with it or pouring it. Kids will also notice that slime does have a scent as well, so they are engaging four of their basic senses while playing with and creating slime.

Cognitive Skills

While making slime or even customizing slime, a child will engage many aspects of their brain activity. They will be able to further engage their imagination. They will also learn more about problem-solving as they work to come up with the right texture of slime they desire.


Creating slime is a good activity for parents to share with their kids. Therefore, spending some quality time together as they create the sticky substance is a great bonding activity. Sometimes, it might be essential for a parent to do this to ensure that a child is using the kit correctly and to make sure that nonedible ingredients are not ingested. This is also a project that siblings can participate in together since slime is something that both boys and girls love to play and no doubt create. So, slime making could be a fun project that the whole family could enjoy together.

Motor Skills

Slime is one of those substances that kids loves to move their hands through. They also love to spread it on a properly covered surface and rub their hands around in it. Even in making slime, there are movements such as mixing that will add to dexterity. It will also help them to fine-tune their fine-motor and communication skills, as a child learns to identify words such as sticky and gooey as they explore the substance of slime.


Creating slime is kind of like a do-it-yourself science experiment. In order to make slime, kids will need to follow the instructions included in the slime-making kit. Kids will learn things such as how to properly measure ingredients and how to identify each one. So, there is a learning process involved in creating slime but all a child will see is the fun they are having. There is also a lesson in responsibility as a kid could learn that after the fun of making the slime and playing with it is over, then it’s time to clean up the mess.


Frequently Asked Questions
Q: What is the best place for a kid to use a slime-making kit and what preparations are needed?

A: As far as location goes, this could be anywhere there is a good clean surface in the house that would be out of the way. This could be a spot in the basement or the attic, even the kitchen table. If so desired, a child could also have a spot in the garage, or outside on the porch or even in the yard to do their slime-making. It is important, especially in an indoor spot, to always make sure that the table, floor or furniture is properly protected, using a tarp or newspapers. When the spot is determined, it is a good idea that the child wears an apron or a painting smock over their clothes, and even plastic gloves since the process could be messy.

Q: What is a basic recipe for the slime that can be made at home?

A: As stated above, there are basic recipes for making slime using basic ingredients found in the home. Here is a simple one using cornstarch, water, and food coloring. Add ingredients to a mixing bowl and stir to combine. Anyone who has added water to cornstarch knows that it will start to become sticky. Add water until you have reached the desired consistency and then add food coloring to give the slime color. This is a way to make a very basic, quickly made slime. For those children who are very interested in science and who might want to explore slime and its ingredients in more detail, one of the slime-making kits on our list will fit the bill. They also might want to create several variations, such as glow-in-the-dark or glittery slime, and to stretch their imaginations a bit more, which is where a slime-making kit such as the one listed above would be a welcome gift.

Q: Where did the slime craze originate?

A: Perhaps the first introduction of slime in pop culture dates back to 1979 when a Canadian sketch comedy show called “You Can’t Do That on Television” used the substance as one of its gag tools. The show aired for 11 years and was quite popular on the kids’ cable network Nickelodeon. Since this time, the network has also incorporated slime into some of their game shows such as “Double Dare” and “Figure it Out.” They also continue to use slime as a staple for the annual “Kids Choice Awards.” Slime was also used as a key prop in the 1984 blockbuster movie Ghostbusters, which only added to its popularity. So kids saw the sticky gooey stuff as fun and wanted to play with it, and, before long, the slime was mass produced and marketed as a kid’s toy and slime-making kits followed.

Q: How do I get slime out of clothes and carpeting?

A: One of the best ways to remove slime from anything is with vinegar. Pour vinegar into a spray bottle and saturate the clothing or carpet with the slime stain. Then, take a clean dry cloth and wipe it off. It’s that simple to remove.

Q: Aren’t glue and Borax that are found in some slime-making kits toxic for kids?

A: Yes, these can be harmful if ingested. But with most slime-making kits, there are warnings about not ingesting any of the chemicals used. This is why it could be advisable for a parent to at least go over the instructions with a child or to even be present when a child is making the slime to make sure they understand. Also, with these, inhalation could also be an issue especially with glue, so it is always a good idea to have a well-ventilated spot or even to do this outside, where inhaling fumes won’t be a problem.

Q: Does playing with slime or creating slime help to relieve stress?

A: Actually in addition to the above benefits, this could be another one as well. But when we stop to think about it, there is something relaxing about moving our hands through gooey slime, or even making it for that matter. After all, some of us find it relaxing to make stuff and to be creative so why should making and playing with slime be any different? It is certainly something that could make a person laugh and forget their troubles for a while, so when we think of it that way, there are also benefits for kids of all ages.

Q: How many different consistencies of slime are there?

A: This is a very good question which doesn’t have an easy answer. Why? Because there are many different types of slime. There is the kind that is runny and loosely goes through the fingers. There is also a type of that is more rubbery and stretches. There is also a type that is more like foam and there is one that seems a bit more solid, like clay. Then, there is the kind that will glow in the dark or will be glittery. In other words, slime can be quite different, depending on how the child creates it.
