Silly Slime with your hands until smooth.
Any 3-to-1 measure of glue solution to Borax solution will create Silly Slime (the glue contains polyvinyl acetate, which reacts with Borax). For example, 1 tablespoon Borax solution and 3 tablespoons glue solution will make a smaller quantity, while 1/3 cup Borax solution to 1 cup glue solution will make a huge amount! Silly Slime will also act like Silly Putty and copy newsprint when laid over the paper and pressed down firmly (comics are fun!). Store in a zipper-top plastic bag.
