I just wanted to let you know I uploaded a video that almost everyone will find interesting. Have you ever wondered how many helium balloons it would take to lift a human being off the ground? We did it, and the video is the story of what happened. I think almost every human being has wondered at some point in their life what it would be like to be lifted in the air by helium balloons, yet nobody has ever seen it or done it! I have a video of people doing it. Check it out here:
