slime kits

Kids love playing with slime! It’s a sticky, gooey, gloopy mess – and it can also be a wonderful science lesson! Slime laboratory kits can provide young scientists with (very messy) hands-on experience of a wide range of scientific principles. Through fun and safe experiments, they can learn about polymers, viscosity, density, cohesion, the scientific method, and much, much more!

Here are 9 of the best slime laboratory toys for kids on the market today.

What Makes A Great Slime Kit for Kids

When selecting the best slime kit for your kids, you should consider your child’s age, whether you need a kit with or without accessories, and how your child will play with the slime. Most slime kits have these characteristics and features.

Some DIY slime kits are all-in-one kits that contain everything kids need for creating many slimes, including colors, glitter, glue, containers for storage, accessories, measuring cups, and mixing bowls. Other kits include the lab equipment but no slime materials; kids use household ingredients like glue, cornstarch, and vinegar.

Depending on your child’s age and interest, you may opt for a slime kit with pre-made slime, ready for play. Some kids enjoy the mix-ins and accessories that create glowing and glitter slime, while others prefer the texture of playing with plain slime.

Check the safety standards of the slime kit to make sure the ingredients are safe for kids. Child-friendly slime toys are generally borax-free and contain non-toxic materials. Slime kits with borax powder or borax solution may cause skin irritation. Some types of glue, like Elmer’s glue, are kids-friendly and washable.

Adult supervision is advised when children play with slime; younger kids could accidentally swallow accessories and mix-ins. Even safe items can be harmful if children get ingredients in their eyes or mouth. Most manufacturers recommend slime kits for children at least six years old.

Some kits come with airtight storage containers for storing the slime for reuse. Parents can use resealable bags if the kit doesn’t have storage tins. Check the shelf-life; some slime isn’t reusable. When the reusable pre-made slime is too stiff, add water to make it more pliable for play.

Slime kits can come with one color or a rainbow variety. You might get various squishy slime powder in different colors, or kits that kids use ingredients like food coloring to color the slime. Kids love to play with glitter glue and glow-in-the-dark powder creating sparkling slime or adding accessories like beads to make the slime more colorful and exciting.

Although children work from a clean surface, their play area can become very messy. Check if the items are washable. Should kids spill storage containers or get slime on their clothes, soaking in distilled white vinegar and scrubbing off with warm water should remove any non-toxic formula that gets into kids’ fabric. Make sure you wash the clothes before the color stains them.

Slime kits with mix-ins and accessories often come in sturdy tins or containers for storage to prevent spillage, reducing the messing factor.
