Rubber Balloons

Experiments with rubber balloons and rubber sheets have led to surprising observations, some of them hitherto unknown or not previously described in the literature. In balloons, these phenomena are due to the non-monotonic pressure-radius characteristic which makes balloons a subject of interest to physicists engaged in stability studies. Here is a situation in which symmetry breaking and hysteresis may be studied analytically, because the stress-stretch relations of rubber - and its non-convex free energy - can be determined explicitly from the kinetic theory of rubber and from non-linear elasticity. Since rubber elasticity and the elasticity of gases are both entropy-induced, a rubber balloon represents a compromise between the entropic tendency of a gas to expand and the entropic tendency of rubber to contract. Thus rubber and rubber balloons furnish instructive paradigms of thermodynamics. This monograph treats the subject at a level appropriate for post-graduate studies.

It's party time, and balloons are everywhere! But where do balloons come from? Who invented them? What are they made of? Discover fun facts about balloons that you can share at your next party in this insightful book.

This high school textbook introduces polymer science basics, properties, and uses. It starts with a broad overview of synthetic and natural polymers and then covers synthesis and preparation, processing methods, and demonstrations and experiments. The history of polymers is discussed alongside the s

The easiest-to-follow and most comprehensive balloon-sculpting treasury available, this amazing book is packed with over 100 unique designs. Gerry Giovinco presents step-by-step cartoons and schematics that anyone can use to recreate these sculptures. You can start out small with a one-balloon dog and a princess hat and build up to a monkey in a tree, an intricate motorcycle, and reproductions of classic cartoon characters. Gerry clearly explains and shows the sizes of the bubbles you'll need to make as you build your sculpture from the knot up, and he demonstrates the unique folds and twists that result in finished works of art — and instant smiles. Gerry Giovinco is an acclaimed artist, cartoonist, and entertainer. In his clown persona, Captain Visual, he performs and teaches the craft of balloon sculpting throughout the country. The Big Book of Balloon Art is simple enough for kids, and it's great for parents and teachers too. Even seasoned performers will find it a practical and fun-filled way to improve their skills.
