Science Experiments

Today we did some science with Mrs Minehan. We got 3 white flowers and we put them in cups of water and then we put 6 drops of food colouring in the cups with the flowers in them. After a couple of days they started to change the tiniest bit. They weren't changing enough so Mrs Swinburn put in some more food colouring in the cups. After that it started to change a lot. The reason why the flowers changed colours is because the food colouring got sucked up the stems and then that changed the petal colours. I want to know in the comments if you have ever done an experiment like this?
