Edible sensory play alternatives?

What are your favorite edible sensory play activities…? I figured this would be a great place to ask, since so many of y’all are so creative… I get asked all the time about sensory play activities that kids love and maybe can even get in on setting up. I’d love to hear your ideas about what’s worked for you kids. Your ideas will help me give families alternatives and this will help them keep their kids safe from non edible alternatives with unknown ingredients.

TIA
