science fair experiment

On Friday we decided to do a science fair experiment.Our experiment was making stalactites and stalagmites. First we had to get into groups, my group was Kylie, SJ, Sione and Malia. Next we got our ingredients. We got food colouring, hot water, yarn, baking soda, salt and a tray. Some difficult stuff was doing the hypothesis and the research. Then we saw that the baking soda worked because the crystals were growing for the baking soda. I felt so excited and it went really well.
