Nontoxic school glue (clear for transparent or white for opaque)
1st bowl - Mix 1tsp of Borax and 1cup of water (dissolve)
2nd bowl – Add 1 bottle of glue & ½ cup of water & food coloring (mix)
Then add glue and water mixture to borax and water mixture. Keep playing with it until it becomes slime consistency.
