Things You'll Need
Instructions
Pour a small amount of liquid latex into a plastic cup. The amount depends on the size you want your ball to be.
Mix an equal amount of vinegar into the latex, stirring constantly with a craft stick.
Continue stirring until the mixture begins to congeal.
Remove the congealed blob with your fingers and work it into a round shape. Continue to work the latex until it can hold its shape.
Hold the ball under running water, squeezing out any trapped vinegar and air bubbles.
Pat the ball dry with a paper towel.
