Buying Guide for Slime Kits

Why buy a slime kit?

Slime kits are a hands-on way to express your creativity and have some fun. They’re great for kids of all ages and can even be used by adults as a stimulating way to relieve stress. Fun activities like slime kits are great for keeping kids engaged.

What should you look for in a slime kit?

  • Material: One of the great things about slime kits is that they’re usually made with non-toxic materials. Slime kits are a safe way for the whole family to have fun! There are even glow-in-the-dark slime formulas for even more unique creations! Despite the safety of slime kits, it’s essential to keep in mind that slime is inedible, so it’s important to prevent your children from eating them.
  • Supplies: Most slime kits come with a variety of supplies for customizing your slime creations. They typically come with a non-toxic glue base, activator, fragrance oils for aroma, as well as fun extras for making your slimes unique. From glitter to colorful beads to unique charms, the possibilities are endless when it comes it making slime. These DIY kits give you and your kids the freedom to get as creative as you want when it comes to concocting fun slime creations!
  • Textures: Slime comes in a variety of textures, from thick, glossy bases to fluffy cloud formulas to icy and jelly-like textures. There are even butter slimes that are soft to the touch and incredibly easy to play with! These fun and interesting textures make playing with slime stimulating and relaxing. If you prefer slime kits with a wide variety of textures, it’s essential to choose a kit with add-ins like fake snow, beads, and jelly cubes for fun and unique textural sensations.

How do you store your slime creations?

It’s essential to store your new slimes in an airtight container in a dry, cool area. If you store your slime in an area that’s too warm, your slime will be prone to melting. It’s also essential to play with slimes with clean hands because they can easily get contaminated when they come into contact with food or dirt. If your slime does spoil, simply dispose of it in the trash.
