How much helium does it take to lift a person?

The Aéroplume, in France, is a helium blimp sized for one person. €60 gets you half an hour's flight. I had to try it. ■ More about Aéroplume: https://aeroplume.fr ■ This isn't sponsored: I paid for my flight at the normal price, I was the one to contact them asking permission, and Aéroplume had no editorial control. I am, however, amazed that in the ten years this has been going, no-one's ever told me about it before!
