This round in STEM class, we have been doing a lot of experiments during the class. One of the experiment that I love and I wanted to share with you is putting mentos into coke. I usually see them tasting and doing this experiment in youtube, but during this class I can see how it work and see it in my eyes clearly. I never think that chemical reaction is realy, but after I’d learn STEM for entier of hours, I can change of lot of things that I thought crazily before and making a real process of understanding of science work.
