It’s squishy. Who doesn’t love to squish things in their hands?
It’s slimy. Slime is the consistency of real slime without the mess. and we are allowed to play with it.
We can make stuff and add stuff. We can add styrofoam or change the colour of the slime with ease.
plus, it’s pretty much a more fun version of a stress ball…
Other than the fact that it’s fun, exciting and tactically stimulating for them (as other people have mentioned), it’s also a huge trend right now.
Somewhere along the line it got picked up and spread, as these things often do. YouTube videos on popular channels aimed towards children started talking about slime, which makes it of course a conversation topic in the children’s schools. This of course encourages others to try it.
Kids are obsessed with it simply because other kids are obsessed with it, and like all trends, it’s going to die down eventually. For now, make sure they’re staying safe and not using any potentially dangerous ingredients to make it!
