Helium is a colorless gas that is commonly used in various ways. One of the most common uses is in balloon inflation, where helium replaces air and helps balloons float up into the sky. Another use is in balloon decoration, where helium is used to create beautiful patterns and designs on balloons, which can be released into the air as a way of expressing creativity and fun.

However, the use of helium should be carefully considered, as it is a non-renewable resource and can have negative effects on the environment if not properly managed. Therefore, it is important to use helium carefully and responsibly to protect our planet and ensure its sustainability for future generations.
