Are there any potential risks of playing with balloons? For the most part, any risks are common sense, like being careful when popping the balloon. However, Phillips notes, “When you inhale a balloon, it displaces oxygen, and you are only getting helium. This can lead to dizziness, light...
Storms are extremely hazardous for hot air balloons, because of the danger of a lightning strike. Even rain is a problem, because it decreases visibility and damages the balloon material (of course, it's not much fun to fly around in wet weather anyway). And while you need a nice wind ...

How Helium Balloons Work Prev NEXT By: Marshall Brain | Updated: Apr 24, 2023 Floating in GeneralAs long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air. ColorBlind Images/Getty Images Most of us feel comfortable with the idea ...
Out of helium? Forgot to pick up the tank? Don't worry, this video shows you two different ways that you can make your balloons float without using helium! And better yet, these methods use things you likely have around the house, so no added cost!
Of course, if the object is denser (and therefore heavier) than water, it doesn't matter how much water it displaces -- it will still sink. To ascend, a fish must reduce its overall density by increasing its volume without significantly increasing its mass. Most fish do this with ...

Picoballoons are very sensitive. You can't just fill them with helium and launch them. They really don't like that. Let me explain. If the buoyant force is too low the balloon will not rise up (obviously). BUT, and this is the catch, if the buoyant force is too high, the balloon...
