Dr. Stone S4 - Episode 2

The Kingdom of Science prepares for departure on the ship "Perseus" and begins a creative drink experiment. Some characters create and enjoy a wheat-based beverage to boost morale, while for those who prefer no alcohol, special non-alcoholic cocktails are prepared through precise scientific methods. This process showcases both the group's ingenuity and the lighthearted, social moments of their preparation.

Meanwhile, the warrior Matsukaze shares a tragic story about a "petrification weapon," hinting at a greater threat. His memories highlight the seriousness of their mission and his personal motivation to grow stronger, which moves Tsukasa to consider reviving an old ally named Hyoga. This decision underscores the importance of experienced fighters on the team in the face of upcoming challenges.

After the ship sets sail, cloudy skies threaten to hinder navigation. To solve the problem, they use a fascinating mineral called calcite, which splits light into two images. This creates an improvised "sunstone," allowing them to locate the sun even through the clouds. With scientific finesse and teamwork, the crew finally reaches the coast of America.
