Is a 1-twist spin of a knotted trivalent graph unknotted?

The twist spin of a knotted trivalent graph is a foam that has simple closed branch lines that do not cross. Thus the foam is a surface with addition disks attached. Using an idea of Marumoto and Nakanishi, we show that there is a nontrivial foam obtained by a 1-twist spinning of a knotted theta-curve.
