Poof balls are not so different from foam cubes. This is another easy way to make crunchy slime with a lot of texture. Try different size poofs to get the texture you want. Since they are light, stretching the slime will still be able to hold them in place without weighing your concoction down. Vary the colors of the balls to make it even more appealing to the eyes. Be sure to start with less poof balls than what you need and then keep adding them in because it will be very difficult to remove them later.
