Whatever you like to call it, it is a great sensory manipulative staple in our classroom! The children really enjoyed playing with "slime" during our fall semester, so of course we brought it to our demo classes to share with others. Here are a few photos of all the fun we had with goop! You can easily make this at home and store it in an air tight bag in the fridge. If you keep it clean, it can last you awhile!
