My in between everything else project for the last couple of days has been this "Cloud Tramp" rubber #freeflight plane. Theres a commemorative mass launch event in the UK on the 5th August and a few of the local crew are gonna fly em.
A friend of mine who allows her #parrots to #FreeFlight in her home, uses similar vests to keep the bird poop from messing the house, and also for harnesses to leash and keep them from flying away outdoors.
It might sound weird to non-bird people, but it's actually very practical.
