To make one batch (we did two batches) In one bowl dump one bottle of glue then fill the bottle up with warm water and dump that in too. mix.(this is when you add in any little add in's, glitter, hearts, food coloring, etc.) Then in another bowl mix little less then half cup of water with teaspoon of borax. Once both bowls are mixed slowly pour the borax water into the glue bowl and mix well till slime forms. Slime will last a long time if storage in a air tight container. But note that if you add glitter the glitter will sink to the bottom in time ad become hard piece of slime. Have fun!~
