After submitting all three of our new ideas, we ended up using the fishing rod idea... the other ones just got rejected.
Melting the marshmallows was rejected because we can't determine when the marshmallows have been completely melted.
Dropping the controlled mass into a liquid was also rejected because there are too many errors that could occur and we can't measure the water accurately.
The fishing rod idea was approved and we'll begin to test the idea out to see if its non-linear.
