Brand New Ideas

We've come up with new ideas since we didn't like our original idea.

1. Melting marshmallows in a pot to determine how long it takes to completely dissolve.
2. Dropping a controlled mass into a fixed volume of liquid in a container to see how much liquid is lost.
3. Hanging a mass off the end of the line of a fishing rod to determine the change in height.

The first idea was Nancy's idea and we've established that she's a pyromaniac who likes to burn things.
