Instructions
Step 1
Balloons are an amazing thing, the direct purpose of which is to give joy. But the balloons filled with helium can not only be pulled by the string, collected in compositions and picturesquely released into the sky. The filler can change the voice beyond recognition, making it thin, squeaky. To do this, it is enough to untie the balloon, put it to your mouth and inhale. Now you can amuse yourself and others gathered with a cartoon voice.
Step 2
The balloon filled with helium rushes into the sky because this inert gas is about four times lighter than atmospheric air, which consists mainly of nitrogen and oxygen. For the same reason, inhalation of helium affects the timbre of the voice - due to a different frequency of vibration of the air and the speed of sound propagation. But the very structure of the vocal apparatus is not affected by the inhalation of an air mixture with unusual parameters of density and viscosity. Therefore, the beeping effect lasts as long as there is an exhalation of air containing an inert gas.
Step 3
Is it harmful to breathe helium? No, air mixtures containing this and other inert gases are used for breathing during deep diving. Another thing is that a mixture containing less than 16-17% oxygen is unsuitable for breathing. But while inhaling from the balloons, no one has ever suffered.
