In case I don't get around to adding this to the experiments page, here's instructions for candy melting fun.
Cover a baking sheet with tinfoil
Unwrap your candy and put it on the sheet. (Caution: never melt a jawbreaker!)
Place in low oven (300-350 F) and wait to see what happens.
Microwave: use a microwave-safe plate and watch your candy (not jawbreakers) as you heat it. Most candy melts in a minute or less. If you heat it too long, you might scorch your candy or even your plate, so choose your dishes carefully and keep a close watch.
You might be surprised at what melts and what doesn't!
