Perhaps counterintuitively, the surface area of the inflated balloon is less than the surface area of the circular sheets. This is due to physical crimping of the surface, which increases near the rim. "Mylar balloon" is the name for the figure given by W. Paulson, who first investigated the shape. The term was subsequently adopted by other ...
In 1964, NASA launched Echo II, a 40-metre (131 ft) diameter balloon constructed from a 9-micrometre (0.00035 in) thick mylar film sandwiched between two layers of 4.5-micrometre (0.00018 in) thick aluminium foil bonded together.
Mylar balloons can cause headaches for linemen in a couple of scenarios: They can get caught between and make contact with wires, or they can float directly into transformers. A cluster of ...

The balloon law prohibits the sale or distribution of a balloon that is constructed of electrically conductive material (metallized Mylar or foil) and filled with a gas lighter than air (helium), without affixing an object of sufficient weight to the balloon to counter the lift capability, affixing a specified warning statement on the balloon ...
Party balloons are mostly made of a natural latex tapped from rubber trees, and can be filled with air, helium, water, or any other suitable liquid or gas. The rubber's elasticity makes the volume adjustable. Twisting balloons can be used to create decor centerpieces for events and to create a more unique look than can be provided by foil balloons.
