Slime can become too sticky when left in the sun, in hot weather or if it has not been played with in a long time. Don’t worry it can be fixed!
Wet hands with activator, rub between fingers, front and back of hands. Start kneading slime.
If the slime is still to sticky spray some more activator onto your hands and knead.
Keep repeating process very slowly as you may over activate your slime.
