Mix 1 part epsom slat to 1 part boiling water and let the mixture cool. Have the children make a crayon drawing on paper. The mixture can be brushed over the picture and crystals will form as it dries. Let the children observe the crystals forming.
This turned out even better than I expected it to. It doesn't take very much solution to cover the paper.
