Drops per minute:32 drops
Watercolour: lemonade colour like white



Conclusion: The first minute the water was dripping small and little. It was also cleaner than before. The second minute the water went darker and dropped slowly. The third minute it went cleaner put it was still dirty. In the fourth minute its getting cleaner every minute. On the fifth minute, it dropped all the water at the bottom.
 Our water was white at the end with a tint of green. The water dropped 32 times a minute. At the top, the bark, leaves and the dirt stayed at the top. The filter paper stopped lots of bad stuff like dirt go through the paper to the bottom.
