This would be a fun, sensory friendly costume idea.
Just in time for Halloween!
This is a great sensory play activity for small children that may be tempted to put it in their mouth. It can be used for up to 3 days.
6 large marshmallows
3 tbsp of corn starch
2 tsp coconut oil
Combine all the ingredients together in a microwave-safe bowl, and heat until the marshmallows expand (about 30 seconds). Mix with a spoon and begin kneading the dough together with your hands.
