Slime 101

Always wash your hands before and after playing with slime. Slime is best when kept in a cool environment. Keep out of direct sunlight.

Why is my slime sticky?

Slime can get sticky if it gets too warm or if it has been left and starts to deactivate, but don't worry! It's easy to fix:

  • First find a clean and clear surface.
  • Open your slime, add a couple of drops onto the top and a couple of drops to your hands.
  • Remove from the container onto your surface and knead in the activator for 10-20 seconds.
  • If your slime is still sticky, then add 2-3 more drops of activator and knead again.

Don't add too much activator as this will over-activate the slime and make it tough. Always add in small amounts and knead thoroughly.

My slime is too stiff

Leave your slime for a little while and allow it to come up to room temperature. If after this it's still stiff, then add a couple of drops of warm water and knead.

My clear slime has gone cloudy

When you play with clear slime it will create tiny air bubble which can make the slime go white or look cloudy. This is completely normal. Just leave your slime in the container for up to a week and it will clear up again.

The floams beads in my crunchy slime keep falling out

With floams and crunchy slimes, a little fall out is normal. If an excessive amount of beads are falling out, this is because the slime has had too much activator added to it. To fix this, leave your slime in the container at room temperature tor a while so the slime can break down.

What is Slime?

Slime is a stretchy and squishy sensory toy for girls, boys and adults alike.

Our Slime Making Kits and DIY Slimes are a fun way to get children interested in science. Slime is a polymer made up of very large chains of molecules. Chemical bonds are formed when you mix the PVA glue and a slime activator together. Activators (saline solution, borax or liquid starch) change the position of the molecules in the glue; this process is called cross-linking.

Not only are slime kits and slime play educational and fun for all the family, but they can also be incredibly beneficial for children by:

  • Helping strengthen fine motor skills through creating and manipulating slime.
  • Learning cause and effect through mixing different substances.
  • Providing calming sensory play.
  • Improving concentration and focus.
  • Encouraging independent play.

Sensory play is vital in children's development and playing with slime enables children to get in touch with all their senses, focusing on how it feels, sounds, looks, and smells. The sensory aspects of slime can also reduce stress and anxiety for adults.

What is slime made from?

Slime is made from PVA glue and activator. Other ingredients include: lotion, fragrance oils, pigments, glitter, shaving foam, clay, instant snow and foaming soap. These slime ingredients give the slimes different sensory aspects of how they look, sound, smell and feel.

What ages is slime suitable for?

We recommend that our slimes and slime making kit boxes are for children aged 6 and over. We do however have a special sensory slime box just for little hands, recommended for children aged 3 and over.

Do I need to supervise my children whilst playing with slime?

As with any activity for children we recommend that they are supervised at all times, some items may contain small parts and therefore present a choking hazard if swallowed.

Why is my slime sticky?

Your slime may become sticky and melt over time due to heat and exposure to direct sunlight. Sometimes your slime may start to deactivate during shipping due to the changing temperatures and environments your slime box is exposed to. If this has happened to your slime, don't worry, it can easily be fixed.

Included in every slime box is activator and a slime care sheet. Simply follow the instructions on the slime care sheet to restore the slime to its perfect texture.

To keep your slime the perfect texture for as long as possible, keep it in an airtight container, away from heat and direct sunlight when not in use.

I'm buying slime as a gift, will it keep?

We don't recommend buying slime well in advance as slime can deactivate over time. We advise purchasing your slime gifts as close to the date as possible (don't worry we have very fast and reliable shipping). If you are unsure, please do not hesitate to contact us before purchasing.
