Make certain that you talk to the kids before you make the slime because they need to understand that it’s not going to stay rainbow once they start playing with it. They may want it to stay that way, but it’s going to get mixed.

And all this really means is that you’ll just need to make it again and can continue to make it over and over again easily every time.
