Quando era criança adorava ver a tia Yara (minha tia ciêntista) fazer experimentos. Sempre fui super fã dela e dos experimetos! Até hoje posso ficar horas olhando para esse video e tentando descobrir o que causa essa reação.
Growing up, my scientist aunt Yara (A.K.A. tia Yaya) used to perform many experiments with us. I was always a big fan (of her and the experiments!). And I still am -- I can spend hours staring at this video trying to figure out how it works.
