How long will homemade slime last?

The slime shouldn’t go bad if it’s stored correctly.  When you take the slime out of the container, if it’s too sticky, you can add more liquid starch. This should help it return to the consistency that you prefer.

If the slime is too stiff, we recommend mixing in a small amount of hand lotion. You can add approximately 1 tsp at a time until the slime is back to the stretchiness that you prefer.

The slime should last up to 2 weeks if stored properly.

What is the difference between foam slime and floam slime?

A lot of people gets these 2 things confused and who can blame them since the names are so similar.

  • Foam slime is a type of slime that has shaving cream added to it. This makes the texture fluffy. You can easily turn this birthday cake slime recipe into a birthday cake foam slime by adding 1-2 cups of shaving cream (the foam type) to make it fluffier than the original recipe.  Just mix the shaving foam in prior to adding in the foam beads.
  • Floam slime is a traditional slime recipe in which small polystyrene balls have been added to the slime to make the slime easier to mold into different shapes.  This recipe is to make birthday cake floam slime.

Now you are an expert on slime too.  Your kids are going to be super impressed with all your new slime knowledge!
