This idea was inspired by something I found on Pinterest a while back. For this activity, I poured a small amount of several different color paints on a paper plate. I then placed a marshmallow in each paint. I used mini-marshmallows but jumbo would work well, too. Several different sizes would make an interesting picture, as well. My daughter used the marshmallows to stamp all over her paper. I think the painting came out very well and will be hanging on our refrigerator for a while!
