How To Store Slime

As with all slime, your Halloween slime should always be stored in an airtight container to prevent it from drying out.

As I said above, this slime recipe will last for months but if you do ever find your slime drying out then simply fix your slime by adding a few drops of hand moisturizer to it.

What If My Slime Goes Wrong?

The best way to avoid slime failure is by sticking as closely as you can to the slime recipe!

However… no matter how careful you are slime can still go wrong!

Usually, it’s due to a bad batch/brand of glue… this is why I recommend you use this popular brand of glue for slime making! 

But the good news?
