Hi Ariel,

Looks like noone else has covered a mylar balloon in papier mache!  I have to admit that I have never tried it. Not being very familiar with this type of balloon I asked around. The advice I was given to pass on to you is to make sure that the balloon is fully inflated and tied very securely. Because of the metallic type surface, a release agent would be necessary to stop the papier mache sticking to it. For suitable release agents see:

Of course, you may not need to remove the balloon at all from the inside, in which case you won't need to use a release agent. Good luck with your dolphin...please come back and tell us how you get on with it.
