This unique textural experience keeps kids enthralled as they discover its special properties. Sometimes acting like a liquid, sometimes like a solid, this mixture of cornstarch and colored water is easy to make and provides open-ended experimentation.
Here is the recipe we use in class at The Messy Artist, and as we note – the mixing requires some elbow grease so it’s best for the adults to do that part. The kids can still help out by measuring, and mixing the food coloring into the water. If you choose to color your slime, you’ll want to do it by coloring the water first, before you add in the cornstarch. If you wait until the cornstarch and water are mixed to add the food coloring, you are in for a lot more of stiff mixing. It does however create a more streaky effect if you do it that way. You can also omit the food coloring and your slime will be the color of cornstarch: white.
We like to do this activity on trays so kids can enjoy it and keep it contained. It makes the cleanup much easier – we just whisk the whole tray away when it is time to move on to another activity.
Accessories we provide children with include popsicle sticks, plastic spoons, little cups, plastic animals, toy people and/or characters to put in the slime. However, we don’t use all of these at once; maybe just one or two at a time.
We do always use popsicle sticks, however, as these allow children who are a little tentative about the slime to play with it without having to touch it and get messy. Children love to cover the objects with slime and let it drip.
