A is for Alcohol dissolve on acrylic

I found this technique in Nancy Reyner's book "acrylic Revolution".
 Use a primed surface for this technique, so the surface is not too absorbent. Be prepared to work quickly.

I choose to try this on a small canvas. Apply a thin layer of acrylic paint to the surface, using either fluid or diluted acrylic paint.

Apply undiluted isopropyl alcohol to the wet paint with an eyedropper, toothbrush, spray bottle, or like me, flicked it on with my finger. Must do this step very quickly, as the thin layer of acrylic paint dries very rapidly and the effect of the alcohol diminishes as the paint dries. The alcohol dissolves the paint and keeps on spreading outward for a few minutes.

Here's the dried canvas:

Also tried this technique on gessoed primed canvas sheet, using the same watered down acrylic paint and applied the alcohol with a toothbrush.
