Canvas Work-mini canvases, oil, rock salt, and liquid watercolor

We love doing canvas work in the art studio.  Today, I offered the Pre-K children mini canvases, liquid watercolors, cooking oil, and rock salt.  We talked about how these materials would react together and to use the oil and salt sparingly as to not add too much to the mini canvases. 

The children experimented with the colors and were excited to add the oil and salt.  We watched as the salt soaked up the paint and the oil created some interesting textures as it spread and mixed the paints together. 

After the paintings dried and the effects from the oil and salt were visible, we rubbed off the excess salt to reveal some cool mini masterpieces.
