Using two clear/translucent smooth
plastic/lucite container lids, I
placed dots of liquid acrylic paints
on the bottom surface, covered it with the
second surface, pressed the dots firmly
until the dendritic patterns formed,
then gently pulled the two surfaces apart.
Next I placed a piece of paper on both surfaces
and lifted off the dendritic pattern
without smearing it.
Results: two mirror-image designs each time.
