It's a bird, it's a plane, it's a floating table! Here is the perfect use for that old DJI phantom drone you have laying around. 

This is a snap-on landing gear mount for a 12oz can. It is designed to work with the Phantom 1 and 2. I don't know if it will work with the Phantom. The holder really just cradles the can. It stays in place mostly due to gravity. If you are feeling extra cautious you could use a rubber band too.

You can use it to carry a can wherever you can fly. Useless? Maybe. Awesome? Definitely.
