Frequently Asked Questions


Slime Care


♥️ What is a slime activator, and how should it be used? 

  • Using a slime activator is necessary to create and maintain the chemical reaction that results in slime.
  • Before playing with your slime, carefully touch it to test if it is sticky.
  • If it is sticky add tiny amounts (drops) of slime activator at a time.
  • BE CAREFUL: slime can get over activated quickly.


♥️ How to make your very own slime activator: 

  1. Take the borax dust that is included in your order.
  2. Measure 1 cups of warm water and add your activator dust (alternatively you can only measure 1 cup of water and add half of your activator dust (1/2 teaspoon).
  3. Stir until all of the powder is fully dissolved. Done!


♥️ Is your slime too hard/stiff? 

Opaque (white glue based): Add small amounts of lotion and mix it with the slime until you get the consistency you want. If that doesn't work, massage your slime in hot water. 

Clear (clear glue based): Leave untouched in its airtight container by the windowsill or somewhere it can absorb sunlight for a few days. 


♥️ Is your slime too sticky? 

Add small amounts of activator and mix it in with the slime until the consistency you want has been achieved. 


♥️  Is your slime deflated? 

All slimes can deflate over time and this is very natural and unavoidable since slime is mainly made out of glue and water. This process varies depending on type of slime (clay/butter/self-inflating slime tends to be deflated faster than other types of slimes) and use, as repeated exposure to air and skin will make your slime deflate.

But water&activator will fix that right up! Try to add small amount of water at a time until your desire texture and volume. If it feels sticky after adding water, that's completely normal, add tiny amounts of activator at a time.


♥️ How long will my slime last? 

Slime should last for a long time as long as it is taken care of properly. Always keep it in an airtight container and a cool environment. Make sure to wash your hands before and after playing with slime so that it does not get dirty and produce bacteria.

However, slime does not last forever since it is a liquid substance! Slime will lose its moisture and may shrink or melt overtime. Slime that is properly cared for should last for a few months.
