We have not done many crafts lately, so today while little tot napped, the big kids and I went outside for some fun.  We poured bubble solution into some paper cups.  We used food coloring to tint each cup a different color.  I gave each kid a sheet of cardstock, and then they blew bubbles directly onto the paper. The bubbles pop and splatter to make neat designs on the paper.  It entertained them for a while!  I suppose you could buy the Crayola colored bubbles and do this as well!
