in class we did a stream table lab. My table did how different types of liquids affect how much erosion occurs. The liquids we used were 7-up, orange juice,and water. We used a plastic water to fill up the liquids and pur down the stream table. Then we measured with a ruler how deep the erosion was at the starting point of where we pured the liquid. We predicted 7-up would erode more becasue of the carbonation but we were proven wrong, water actually eroded the most.
