Theme:"Building a Better Mousetrap"
Question 1: While you could sell the scrap, you're better off patching this up and getting a cool $250 early on.
Question 2: A little misleading, this won't become a musical instrument, but rather a helpful item the whole group will enjoy.
Question 3: Its original use is unknowable, but Jeff can still make use of another man's garbage. (Note: there are two acceptable answers for this question, but you only need one of them!)
Answer 1: Broken Spray Can
Answer 2: Broken Trumpet
Answer 3: Broken Machine / Broken Gadget
