When shopping for a slime kit, be sure to consider the kit's difficulty level, because some kits are more advanced than others. For kids who are new to making slime, look for kits that require only three steps. Choose one of the more complex slime kits with extra ingredients for increased customization for the kids who are slime-making pros. 

Make sure that the kit provides everything you need to make slime. Some slime kits come with all the ingredients and utensils, while other kits provide only the basic ingredients. So, if you're not thrilled about using your kitchen mixing bowl to make slime, check if the slime kit you choose comes with bowls and stirring utensils.
