Elixir

The bottle opened. Nobody had touched it; the top just flew off. Nothing remarkable about that. It had probably been shaken up a bit and perhaps the top wasn't on too securely anyway.
The next bit was truly remarkable. Liquid arced out of the bottle and into the glass on the kitchen table a good twenty feet away.
The orange juice in the glass was marginally diluted by the liquid, which stopped arcing after two seconds.
The woman hadn't seen it happen.
She took a mouthful of juice and thought that it tasted funny. It didn't stop her finishing the whole thing though.
Within a few minutes she was floating above the table, both literally and figuratively.
It lasted for about a minute and then she crashed to the floor, instantly losing consciousness. She came to 17 hours later and had a hangover that lasted for almost a week.
The bottle sat on the worktop, unnoticed by the woman, who remembered nothing of the incident.
