How to make slime using Cornstarch

My son has been asking me lately if we could make slime. So I thought I would post an easy slime recipe using Cornstarch since Borax can aggravate some people’s skin, especially among children.

slime with cornstarch


1 Cup Cornstarch

1/2 Cup Water

1 Bowl

1 resealable bag

Glitter for color (optional)


Pour Cornstarch into a bowl. Add water slowly while mixing the ingredients with your hands. Add color (optional). Transfer slime in a resealable bag. Store slime in the refrigerator. You may need to mix it each time before using.

*Also remember that you cannot dump slime down the drain because it can clog your drain.

    This is a great recipe – I had never made slime before as my recipe calls for Borax as well and it just never seemed mild enough for us. Thanks so much for sharing!

    My son has very sensitive skin and he is allergic to an ingredient in borox. This recipe is better than any other and it does not irrtate his skin. Thanks!!! :)

    This unfortunately is more “goo” than slime and is definitely not a replacement. Tried and was very disappointed. Maybe still acceptable for young kids.
