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 ...
Balloon skewer experiment. A pin or needle is frequently used to pop a balloon. [4] As the needle or pin creates a hole on the balloon surface, the balloon pops. However, if tape is placed on the part where the hole is created, the balloon will not pop since the tape helps reinforce the elastic tension in that area, preventing the edges of the hole pulling away from the center. [5]
Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.

The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil. This gives metallised films some advantages over aluminium foil and aluminium foil laminates.
