Freezer
Whether we’re talking about frozen pizzas, leftovers, or any other frozen treats, all these items will keep freezers tightly packed and crowded.
One more container in the freezer won’t draw the attention of potential thieves, which makes it a wonderful place to keep cash and other valuables. All you have to do is make sure that the container and its contents are freezer-safe, and they won’t damage your items.
Tennis ball and soccer ball
Very similar to using a hollow book or an empty can, a tennis ball or even a soccer ball can be easily modified to make a secret storage spot.
Tennis balls can easily retain their shape even after you cut them, so they won’t assume that the ball was cut in the first place. This opening is wide enough to store a proper roll of cash or any other small valuables, such as earrings and rings.
Drop ceiling
A drop ceiling is a useful feature that’s very common in finished basements, laundry rooms, and even utility rooms. It could easily serve as a concealed storage location for some of the most important lightweight items.
The dropped ceiling mainly consists of multiple panels supported by narrow metal frames. All you have to do is lift a panel to get access to the hollow space above the drop ceiling where you can stuff a lightweight package, such as an envelope, bag, or even a small box.
