Elf house on a tree! That would be cute in the garden, especially in the tree over grown with ivy. How about some battery tea lights in the windows during outdoor parties. I hear the fairies/elves whispering "home school project" in my ear.
dripping faucet I'm so doing this in my yard. it won't be a working faucet so no need to have it tapped into the water line. just a pipe and faucet from the hardware store and a crystal from the craft store, and an old bucket from the thrift shop.
