Creativity for Kids Grow N' Glow Terrarium Review
This is the best 6 year old gift for the young scientist.
It doesn't get any cooler than having your own underwater world with plants and rabbits and stickers that glow in the dark. Your son will get to grow his own wheat and chia seeds in an adorable terrarium he can design himself. He'll take pride in seeing his world grow and and change every day, and will love watching it glow at night.
