Bring Water to a boil, add gelatin, and stir until completely dissolved.

Mix the birdseed into this mixture.

Cut the apples in half lengthwise and hollow out the insides with a spoon or knife.

 Fill each apple with bird seed mixture, set on a sheet pan, and put in the fridge for 1-2 hours or until firm.

Poke a screw into the top of each apple and tie a piece of twine to it.

 Hang outside for all the birds to enjoy!
