Alka-Seltzer dissolves when it touches water.
We covered an entire tablet with our Halal nail polish. We made sure to cover every side of the tablet & dropped it into water to test permeability. The tablet began to dissolve almost immediately, proving permeability!
We compared the results with regular (O.P.I.) nail polish in the video's second half. The result? The tablet took much longer to dissolve.
