Off topic somewhat but how about a "hundredaire" space flight?

As a kid I was always ordering stuff from Edmund Scientific (in Barrington NJ I think).
I ordered a weather balloon then spent the day using Mom's vacuum cleaner, hose connected to exhaust, inflating it.
Finally it was "YUGE!"

Then what to do. It wasn't a windy day but hard holding onto, of course no lift but bulky.
We lived in the country but off of a major highway so I decided if I could get it down our long driveway across the road was my best friend and he'd be amazed. Somehow I made it...cars blowing horns, people yelling!

Luckily my friend was home and amazed...until it snagged on a telephone pole ripping it apart, but well worth it.
Always curious if you had a big pasture and enough helium to lift your weight less 10 pounds strapped to a body harness what it would be like. Not enough lift but close enough you'd feel weightless.
