The tank looks great, and I love your pictures. It is so important to nurture our children's interests, especially when they are homeschooled.
My daughter became fascinated with the violin, we didn't have money for classes but she saved up for a starter violin and has taught herself watching videos. She can even play a few songs on her own.
