Can you make a mug out of air-dry clay from Crayola and use it?

Yes, you can make a mug out of Crayola air-dry clay, but it's important to note that it may not be food-safe or waterproof once dried. While the clay can be shaped into a mug, it's best to use it for decorative purposes rather than for holding liquids. If you plan to use it functionally, consider sealing it with a food-safe sealant after it dries. Always check the product guidelines for safety and usage recommendations.
