A really easy edible slime recipe, with only two ingredients!
This is one of my favourite slimes. It’s sticky, smooth and stretchy, just like slime should be.
Plus, this slime is made from common kitchen ingredients, and is completely edible (although I don’t recommend making a meal of it). Nothing too flash, nothing obscure and hard to locate. You won’t find yourself wandering around with a shopping list that looks like it’s come from a wizard’s cookbook. Nor will you need to stroll through far flung shopping aisles searching high and low for ingredients you’ve never heard of, and whose names you can’t pronounce. This slime recipe uses pantry staples. Things you probably already have stored.
Cornflour slime, is also known as oobleck (with a nod to Dr Seuss’ book Bartholomew and the Oobleck), magic mud and gloop. But, whatever you’d like to call it, it is the easiest slime you will ever make. You can whip up a batch in two minutes flat to keep the kids occupied. There really is no magic to it, but there is magic in the results.
The magic of cornflour slime
This very special slime is magic because it’s a Non-Newtonian Fluid. A peculiar substance whose flow changes dependent on the pressure applied to it. Clear as mud?
Let me explain. When you apply pressure to the cornflour slime (for example, by rolling it into a ball) it will hold its shape. But, as soon as you stop it will flow like a liquid. You can try to catch it, but it will simply flow through your fingers and out of your hands. Make some and try it for yourself!
How to make edible cornflour slime
What you’ll need:
- Food colouring (optional)
What to do:
- Pour the cornflour into a bowl.
- Slowly add water until a thick slime forms.
- If you’d like coloured slime, add a few drops of food colouring and mix in.
You’ll need about ¾ of a cup of water for every cup of cornflour you use. If you find the slime is too hard, or too liquid simply adjust by adding more cornflour or more water.
One word of warning. It’s best to dispose of this slime in the garbage bin, rather than the kitchen sink. The cornflour particles are suspended in the water, not dissolved, and will therefore settle and could cause a blockage if washed down the sink.
Tips for playing with cornflour slime
- Try to roll the slime into a ball in the palm of your hand.
- Pop the slime in a colander and watch the tendrils of slime ooze out the bottom.
- Try to squish the slime with a potato masher.
- Use cookie cutters to make shapes in the slime and then watch them disappear.
- Simply put your hands in the slime, and watch it ooze over your fingers.
- Try to pick the slime up with a spoon.
There’s endless possibilities for playing with this wonderful slime. I hope you enjoy it as much as we do!
