Did you know, you can make balloons float, without helium?
Pretty cool! Check this out. No magic here. It?s science I promise. We have air from the fan pushing the yellow balloon up, gravity pulling it down. Where the forces equal out we get balance forces and it floats in the air.<br>
What?s gonna happen when I put the red one on top? Are you sure? Let?s test your hypothesis. Awesome! Both of them are floating.<br>
