Alka-Seltzer dissolves when it touches water.
We covered a tablet entirely with our Halal nail polish, we made sure to cover every side of the tablet & dropped it into water to test permeability. The tablet almost immediately began to dissolve. Proving permeability.
We compared the results with regular (O.P.I.) nail polish in the second part of the video. The result? The tablet did not dissolve for a very long time.
