The kids have been begging me for 3d chalk all summer, I kept telling them it would not work. I finally gave in and who would ever guess the stuff really works. When Meggie came to visit last week she even got excited when she found out we had it. With in the hour of her arrival we had a brightly covered street in front of our house. All I have to say is "Congrats Crayola on making chalk fun for all ages."
