How to Build a Simple Bottle Raft for Kids’ Science Projects #2089472 (License: Personal Use)

This line-art diagram shows two identical floating rafts constructed from four plastic bottles (two per raft) used as buoyancy chambers, with wooden planks laid across and secured by string lashings. The design emphasizes simplicity, accessibility, and educational value-commonly used in elementary science lessons to demonstrate principles of buoyancy and structural engineering. Each raft features capped bottles oriented horizontally, with visible wood grain texture and tight binding points.
