Intended for bath or pool use, Product features include: 1 part hull with internal buoyancy chambers. The buoyancy chambers are intended for HIPS material based on buoyancy figures. Other materials will have different buoyancy results. The model will self-right under all circumstances. These models are fun to flick around the tub - diving and then returning to the surface slowly.
We suggest printing this from vibrant materials so that it is easier to see in the water. Diving into this thing would hurt - loosing a black sub at the beach would be very easy. The rear fins could hurt little feet if dropped on them or stepped upon.
