Iron Imperative
Balloon inflates into unpredictable form. 

Inspiration from Natire
Cephalopoda exhibits non-linear elasticity and the color of its skin changes with disproportionate flexion.

Problem Statement
Balloon is one of the most magnificent human inventions, perhaps next to a city. But what horrible crime balloon artists commit stretching, squeezing and twisting the poor thing. A balloon comes with an innate element of surprise. But artists crush this little sensation with an overwhelming skill of balloon-bending. Sir Richard Buckminster Fuller said that there was nothing in a caterpillar that told us that it was going to become a butterfly. That is how a balloon should inflate too. If it is to take an animal form, it should surprise everyone- even itself.
Nature Review
Different skin systems were examined for their ability to tighten and stretch. The solution was fond in the arterial walls of cephalopod (Cephalopoda). This magical material can demonstrate disproportionate flexibility. It has a non-linear elasticity so it can warp and inflate into any form. Furthermore, the chromatic behavior of the skin changes with flexion, showing us all the ingredients we need to make NatureGadget Surprise Balloons.
Technology Review
Please, see the links in technology montage below for a list of stretchy materials. Patterning of tensile structures has already been achieved with the help of discrete element models using Dynamic Relaxation Technique. Inkjet-printed stretchable IC’s and NOAA smart balloons offer an insight into the possible behaviors of desired balloon.

Nature Gadget
Deflated balloons are similar to eachother but when they are inflated, they take different forms and colors. This nature gadget is mass produced- all units exactly the same in their form and color (12). When a balloon is inflated however (2, 6), it takes form of a surprise organism due molecular-level encoding for disproportionate stretch and color (13- 16).
