Summarize this article for a 10 year old
A twistlock or twist lock, together with matching corner castings, as defined in norms including ISO 1161:1984, form a standardized (rotating) connector system, for connecting and securing intermodal, and predominantly ISO-standard international shipping containers. The primary uses are to securely stack containers, for locking them into place on a container ship,[1]: 4:18 semi-trailer or rail carriage, and for lifting and handling by specific container-handling equipment, like straddle carriers, reach stackers, container-handling forklifts, sidelifters, and various types of container cranes.

Twist-locks also have to be used when stacking containers shorter than 40 feet (12 m) together with 40‑foot and longer containers. Containers shorter than 40 feet containers must be joined together horizontally with twist-locks, to form a rigid combined whole 40 feet in length, to make them stackable and be able to support and be supported by an ISO standard 40- or 45‑foot container stacked underneath or above them.[Note 1][Note 2]
