All parents know that kids just love to get messy. Who hasn’t turned their back for a second, only to find that a certain someone has jumped right in the nearest puddle, or picked up something everyone really hopes is mud? 

Sometimes, the best thing you can do is channel that love of mess into something fun for both of you – which is where this gruesomely appealing, non-toxic goo recipe comes in. Here’s the easiest way to make slime!


How to make slime for kids

So, how do you make slime? If you do a little research, you’ll soon discover there are lots of options … and lots of those options contain things kids can’t eat, like Borax. If your little one has a tendency to bring all interesting-looking things up to their mouth for a little taste, that won’t do. So here’s how to make child-safe slime with just four (edible) ingredients!

You will need:

  • 1 cup of cornflour

  • Up to one cup of water

  • Food colouring

  • Edible glitter

To make the slime:

  1. Pour the cornflour into a bowl.

  2. Add a few drops of the food colouring (green is a favourite here, but anything goes).

  3. Stir in water, a little at a time, until you get the gloopy consistency you want.

This particular type of slime is also known as “oobleck”. It’s hands-down the easiest way to make slime and it’s also perfect for anyone who wants to know how to make a child-safe slime that’s non-toxic. That said, it’s not exactly delicious, so kids won’t feel the need to lick the spoon.

How to make kids’ slime extra-fun

This slime is a little special. Get kids to grab a big clump of it in their hands and shape it into a ball. It will look and feel solid. Then ask then to open their hands and just let the lump sit there. 

See the change? The slime will start to “melt” back into a liquid, oozing between their fingers and slipping back into the bowl! Now try throwing it (outdoors, ideally). The slime will seem to shatter on impact, then turn back into goo in just a few seconds. 

Once you’ve mastered this simple slime recipe, you can easily whip it up any time, using whatever food colouring you happen to have in the house. It’s a lot of fun to experiment with – and there’s no shame in wanting to join in, either. Go ahead and get stuck in.

Don’t worry about any mess, either: with Persil liquid on hand, their clothes will be back to normal (and ready for new kinds of mess) in no time.
