Mikaila of Austin, Texas was only four years old when she took her great-grandmother’s lemonade recipe and used it to open her lemonade stand. Mikaila called it Bee Sweet lemonade and by the time she was 10, she managed to get her lemonade on store shelves in Texas. Her lemonade is also sold in three other states, which are Arkansas, Oklahoma and Louisiana. Mikaila hit it big when she landed a deal with Daymond John on Shark Tank. Sweet!
