Toy balloon

[6] Blowing a balloon by mouth is good for health because it exercises the intercostal muscles, which expand and lift the ribs and diaphragm, improving lung function and oxygen saturation.

[7][8] This exercise can improve posture, stability and breathing patterns, and it helps increase lung capacity, making it useful for conditions such as pulmonary fibrosis, COPD or asthma.

[9] In addition, balloon inflation opposes the diaphragm for efficient breathing and helps increase intra-abdominal pressure, making it a useful exercise for rehabilitation and respiratory function.

[10] Foil balloons are made from an inelastic plastic such as biaxially-oriented PET film allowing them to be printed with designs that are not distorted by inflation.

[citation needed] There have been concerns about metallic balloons causing short circuits when caught in overhead power lines if not disposed of correctly.

These are prepared by tying multiple bunches of balloons on a long string or ribbon, passing one end of the string through a hole of an annulus-shaped disk (or a plate with a hole), and then fastening screws on the disk or plate, with the sharp ends of the screws pointed towards the balloons.

The "firecracker" effect would be initiated by a person (or a machine) pulling on the ribbon and feeding it through the disk, while the noises are generated by the screw tips bursting the balloons in quick succession.

The noises created from a toy balloon are a staple element of sound design in popular media, especially in comedic animation and cartoons to represent inflatable objects in a comical manner.
