Minutes                          1.                         2.                   3.                    4.                       5.

Drops per minute:73

Watercolour: Dark brown

Conclusion:

I take a  video and photo while my group Khyle is counting how many drops in 1 minute.  So the first minute is 73 drop my friend Khyle count, then the second drop in 1 minute is 57 and the third drops in 1 minute is 46 and the last one drops in 1 minute are 38. We also watch how the colour change when we see other people colour almost dark brown, when our one is dark brown.
