Boil water. Add Knox and flavored gelatin. Stir until dissolved. Pour into egg shells. Peel eggs after gelatin is stiff, about 4 hours.

Have egg shells prepared ahead. To hollow egg shells: shake eggs. Make a 1/4 inch hole in large end of egg. Shake out insides. Rinse with water. Set up in egg crates.

Tip: Use a very small funnel or a syringe to put the finger Jell-O into the egg shells.

Tip: Double the recipe and use two different colors of gelatin. Allow first color to stiffen before adding second color.
