Elmer's glue as a base coat. Nails come out shiny like a gel polish. It works better than most base coats. In this photo she used the glue base, 2 coats of polish and seche vite top coat. Might have to try this
Musical nail polish: everyone holds a nail polish. Pass the polish around while the music plays. When the music stops everyone paints one nail with the color they are holding. Continue until all nails are polished.
