The first one we tried was a Planet egg. I saw this one online last year and wanted to try it out. However, I thought something was missing. What goes better with a planet than an alien on a spaceship? I came up with a really easy alien and ship. The boys had lots of fun making the eggs, although Higgins was a little upset that he couldn't fly his alien and the spaceship around.
Alien eggs: Dye an egg green (or blue, purple, etc.). Add on googly eyes and pipe cleaners for antennae. I attached with glue dots. For an extra wow, make a spaceship out of an old egg carton, drink carrier, or toilet paper/paper towel roll (cut out paper triangles and glue on for rocket fins). DM Tip: To get more of a lime green color, I used Betty Crocker Neon Food Gel. I mixed it with a tablespoon of vinegar and about 3/4 cup water to create the egg dye.
