My covered balloon burst its seams before the papier mache dried. Why?
The air inside the balloon got too hot and expanded so that it split the papier mache. Once covered, the balloon must be kept at the same temperature. • My finished work was very bobbly. You probably didn’t smooth down the paper enough and trapped air between the layers. • My papier mache bowl distorted. A certain amount of distortion is expected, and indeed adds to the appeal of papier mache. If your finished work is very badly misshapen though, your glue may have been too watery or it was left to dry in a hot place.
