On white paper draw a large oval with a line down the middle using a felt marker. Cut out a half circle for the ladybugs head and a bunch of small circles from black construction paper. Have the child glue on the head and spots onto the lady bug. You could also use black stickers if you have some.
While they are busy gluing place corn syrup into a container and mix in a couple drops of red food colouring.
Let the kids paint away with the coloured corn syrup.
The corn syrup will give the pictures a shiny textured look when it dries. These take a long time to dry completely, I would recommend leaving them for atleast 24 hours before touching the painted areas.
