Plan B......Casting

OK, i have just come across an idea where i have the chance to cast the balloons and make a sculpture. This would save the hassle of keep blowing up the balloons and also, look quite nice if executed in the right way. So over the weekend i have been grafting and plaster casting balloons with plaster of paris. Below is the outcome of what we did, i am quite pleased with what i have achieved, i am looking forward in trying to make this happen as i think it could look quite nice. I need to smooth them out and paint them now to get a nice looking finish to them.

I also need to find a way in creating the "floating" look of the balloons.
