How would you make a puzzle piece balloon sculpture? Would I need aluminum rod?
I assume you mean a sculpture similar to the one shown in the photo I uploaded?
You are right. You'd use aluminium rod which you have to bend into the puzzle piece shape. For smaller, hanging sculptures we normally recommend 1/4 inch aluminium rod. If you plan to make a bigger, self-supporting sculpture you may want to use 1/2 inch rod.
For a self standing sculpture you also need two bases. You can make those bases yourself, as explained here, or buy ready made ones, like this steel plate from Amazon.
You'd have to figure out a way how to best attach the aluminium rod to the base, as these are made for use with conduit.
You could use a short piece of conduit for the first vertical part of the puzzle piece, insert the aluminium rod into the conduit and secure it with Gaffer tape.
Hope that helps!
