Hoax - ethyl alcohol is a liquid. There is no way to de-liquefy, IJS!
I questioned this in another thread.
The trick is that the liquid alcohol is microencapsulated in tiny dextrose (or something) beads.
So adding water will release the alcohol from the beads. Presumably, the flavoring is mixed in with the beads.
To get a 100 ml drink with 6% alcohol, one would have to add at least 6 grams of beads, or half a tablespoon.
It's already been done with other liquids.
