40 minutes	12	11	22	20
55 minutes	13	13	20	19

Findings:

cup 1 and 2 went up 1 dirge each time but cup 3 and 4 went down 2 digress 

Conclusion

through time one of our cups fell over so that sucked but there was still water left so that was good .
I think that while the cups just sat there the sun was making the water warm so they were going up not down.
