My kids played with this for hours! From digging up bones, putting them together and playing with the skeletons they both had a BLAST with this activity! How to put this together: • Mix 2 cups cornstarch with 1 cup water. • Optional to add coffee grounds for texture. • Place dino bones in the ooblek and allow to dry overnight. • Give your kids digging tools and let them excavate!
