(This may be better for the food science forum rather than the question marathon forum, by the way)
At States yesterday they used cheese puffs, which seemed to be pretty successful. In addition, I have noticed that chips work great although they aren't the easiest to puncture (pro tip: use pringles or corn chips for relatively consistent size+shape). At an invitational they used marshmallows, although I would heavily discourage it considering the fact that marshmallows are not easy to burn through to the center.

It will read negative because the Benedict's test tests for a reducing sugar and sucrose is not a reducing sugar.

Give two examples of a trace mineral.

Answer
spin the egg. The raw egg is full of fluids so it wobbles when it is spinned, whereas the boiled egg spins normally
