Today we checked our plants. Our hypothesis was right. The stem and the petals changed colour! Now.......
I am wondering if we left the flowers in the food colouring for another 2 weeks, what will happen?
What will happen to the flowers if the food colouring was toxic oil? Would the flowers die? Or will they stay alive?
What will happen if we put the flowers in the sun, but the water was toxic oil?
Will the flowers still change colour if we change the food colouring to water?
