Butterfly Feeders

Ingredients:
Small Mason Jars w/ Canning Lids
Cellulose Sponges
Twine
Aquarium Rocks
Sugar
Water

Directions: 
To make these butterfly feeders, we cut small triangles into canning lids and pulled half of a sponge into the triangle, so that a portion hangs out and the rest stays within the jar. We half-filled the jars with sugar water (1 part sugar to 3 parts water, heated on the stove to form a simple syrup) and added aquarium rocks just for funsies. We tied the twine around the jar before adding the lids. Finally, we placed the lids on tightly and hung them in the tree! You have to check their sugar water levels every now and again, but mine have stayed pretty full and very clean for a week now.
