Periscopes are tubes or optical instruments used to allow people, usually soldiers or sailors, to observe their surroundings without being seen.

Perishability refers to the property of a good or service that it has a limited lifespan and becomes worthless or useless once it has expired or gone stale. This can be due to factors such as changes in fashion, technology, or consumer preferences, or because the product has a limited shelf life or is sensitive to storage conditions. For example, fresh food and flowers are perishable goods because they spoil quickly if not consumed or preserved in time, while a new smartphone's perishability may arise from its rapid obsolescence due to continuous technological advancements.
