food coloring (optional)
mix 2% borax with hot water stir until the borax is dissolved you can put it in a bottle or container. Then in another container mix 4% Polyvinyl alcohol with hot water this will take a bit longer to mix into the water. Next put this into another bottle.
Now you can pour some of the polyvinyl alcohol mix into a bowl or something else to mix the slime in now you can put in your food coloring and glitter if you want now add a tiny bit of the borax in at a time and mix well you can stop when your slime is thick enough for you. keep your slime in a container so it doesn’t dry out.
We discovered that the polyvinyl alcohol (PVA) actually takes ages to dissolve. I think in the end we left it a few days.
