On March 27, 2025, Team OXBIT, Chatchawan Bendjerdsirikul, and Phongnakorn Phongsachai from Secondary 5/9 introduced their eco-friendly project to Primary 4-6 students.

Using a fun Detective Conan-themed activity, they engaged students by asking how they could help the environment. They then showcased the OXBIT feed, a product they created after thorough research and experimentation to obtain the correct mixture of ingredients. The product is designed to reduce methane emissions from ox waste while improving milk quality.

Primary 4-6 students had fun participating actively and learned a lot. The interactive and educational session prepared the team for the final competition on April 7-9, 2025.
