Balcony crane
The neighbors of these people are pretty inventive. This hook and pulley arrangement allows them to hoist their items up instead of them having to walk all the way down and then carry said items back up with them. Talk about a brilliant concept. It might inspire others to be more creative and productive.
This is also useful if they need to leave anything for a friend who is unable to pick it up right away. This brilliant hack should be given ten stars. It doesn’t look too hard to try and recreate this at home.
