Bladder of pig Bladder there is airtight. It does not leak air. Germanic tribes is to dismantle the pig, using most of the sites in cooking, but the inedible bladder became the children’s toys. Historically, the pig bladder had several additional uses, all based on its properties as a lightweight, stretchable container that could be filled and tied off.

Intestines of cattle Goldbeater’s skin is the fine tissue forming the outer coat of a cow’s intestine. Strips of about 10 cm are cut, and the fat removed by washing in warm water and scraping with a blunt knife. [sausage] |

|
Baiofilm Bacteria adhered to the surface, such as teeth, to excrete a sticky polymer. It will form a film body for protection. Bacteria, protozoa, algae, they are living in the interior of the biofilm. And help each other to each other, and then organized a closed colony. |

Molecular Amphiphilic molecules having both hydrophobic and water repellency, will automatically form a bag-like bilayer in water. Self-organization |
|
Soap balls By the action of the water surface tension and surface active material, to form a spherical shape is the smallest form of surface area. Thick portion of the soap balls, and extends earlier than the thin part, because the whole film is to become a uniform thickness, you can inflate up to the thinness of the molecular level. When the thickness of the film reaches the molecular level, the wavelength of light is interference, it becomes a pattern of rainbow colors, black spots will rupture appeared to further thinned. |
|
Grass ball In the air blown glass is made by blowing a breath into the glass dissolved at elevated temperature, it is possible to make extremely thin spherical. Temperature difference occurs in the thin portion and a thick portion of the glass of high temperature, because the thick portion is high temperature is extended to the first, and because automatically becomes a uniform thickness.

Chewing gum In the case of rubber balloon, on the contrary, weak thin portion than the thick part, because the thin portion extends increasingly thin, the inflating size is limited. Ethylene-vinyl acetate 1998 Polyurethane Condom |

Blisters Such as when the skin is peeled off in the shoe sore, accumulate moisture in the epidermis, it becomes the balloon-like blisters. Dialysis “Waste removal” of blood “electrolyte maintenance,” “amount of water maintained” |
|
Water spider The internal pressure of the water of the foam is higher than the surrounding by water pressure and surface tension. Carbon dioxide becomes a carbon, and then rapidly diffuse into the water. Nitrogen is left to the end, it keeps the shape of a bubble. When Insects breathe the oxygen, oxygen is supplied from the water. |

Egg cell Eggs are covered with a soft balloon but is protected by the hard shell at the time of ovulation. In the case of aquatic organisms, and growth remains soft balloon. Human beings will grow in the body of the amniotic membrane. And humans break the balloon, and be born. |

Copy food Inside of the polymer balloon, the bud of lettuce was sealed along with the nutrient, artificial seeds have been developed. Artificial salmon roe is a copy food to be prepared by the aqueous solution of sodium alginate applied the jelly-like balloon technology to build by drip to potassium chloride aqueous solution. |
