If you blow up a balloon and weigh it, then let some air out and weigh it again, you will see that the balloon becomes lighter as the air leaves. This shows that the air inside the balloon has weight.<\/p>\n\n\n\n<p class=\"has-text-color has-link-color has-large-font-size wp-elements-38fe39aa3df3808a5b8173bf5f0ee7de\" style=\"color:#000060\"><strong>The Importance of Air\u2019s Weight:<\/strong><\/p>\n\n\n\n<p class=\"has-large-font-size\">Air&#8217;s weight is important for things like weather patterns.
