its BERNOUILLI'S principle.

@ellaissuperawsome Well, Bernoulli's principle in this video might be at work where the balloon is being inflated by a fan (high-speed air stream creating low pressure and drawing more air in). But it is not what lifts the balloon. Difference in air density, gravity pulling the less dense air toward the Earth's center less is what makes it buoyant.

@walkupjoey Actually, 3 YARDS is 9 feet. Every METER is 3 feet and a little over 3 inches.

HI MR HARRISON!!!!!!!!!

[UserIsAnFBIAgent]

That was an awesome video, thank you for the new information, Archimedes Principle(s).

If a 1g foil boat can hold 44g

&

If a 0.5g foil boat can hold 22g

Then a 7.5lb foil boat should be able to hold a 330 lb person..

If an object is less dense then the water it displaces, it floats, I've learned about boats and that, now I'm learning about Hot Air, and Hot Air Balloons. Awesome video, again.
