18: Tennis Ball Garage Hack
The garages that we park our cars in are getting smaller and smaller, which only makes parking more difficult. When it comes to fitting your vehicle into a garage, you want to make sure you don’t hit anything. Tying a tennis ball to the roof in your garage is a great way to make sure that you don’t pull too far into the garage. Once you hit the tennis ball, then you know you are too far into the garage and need to back up (via Family Handyman).
