This project tests how the shape of a Lego boat affects how much weight it can hold before sinking. Three different boat shapes were built and tested by adding weight until they sank. The results showed that the flat-bottom boat held the most weight, helping explain how boat shape affects buoyancy.

We are proud of you and your accomplishments. There is not limits but the ones we create to ourselves. So keep ongoing until you reach the starts and beyond.
