It takes about an hour for a popsicle to melt indoors at room temperature. The melting isn’t obvious for a long time. Once the pooling starts it happens quickly. Popsicles are not as challenging to paint as the shadows they cast. Overlapping shadows contain spots of reflected light. Popsicles are have translucent spots and opaque spots. In the case of a twin pop, there is a spot in between the two pops that is translucent. It is interesting to look at the place where the sticks come out. There is no contact shadow. When the melting starts, color floods onto the sticks like watercolor.
