This one is a a half-truth… yes, you can fill a balloon without helium. Now, I think (correct me if I’m wrong), that it is common knowledge that you can fill a balloon without helium… using those things we like to call lungs. Also, some people on hot summer days have been known to fill balloons with water. I suppose you could probably fill balloons with other things too, but I know that’s not what you are thinking. You saw this:

Problem: Some people have it right… you can inflate a balloon with this method of mixing baking soda and vinegar together. This works because the bubbling “volcano” reaction creates carbon dioxide. However unfortunately, carbon dioxide is not a lighter gas than the air we breath, so it can’t float. So for those of you that repinned this with the comment along the lines of “Wow! Now I don’t have to rent a helium tank for parties!”… Well, you were wrong. Sorry- nice idea for a science project with kids, but as far as using it for that ubiquitous floating party decoration that both boys and grown men enjoy sucking helium out of to make their voice sound like Mickey Mouse, it’s just not going to work. This one’s sunk.
