My wife bought the kids a Creepy Crawlers Kit for Christmas.  I thought it was a great idea because I figured that I might be able to make some plastic baits with it  I wonder if anyone sells the cast aluminum plates that fit in the oven?

This thing looks like an Easy Bake oven that my little girls used to have...it's heated by a light bulb, and the molds more than likely won't be able to take the 300* hot plastic being poured into them, or if you wanted to bake them in the oven, not sure if it would get hot enough to convert the plastic, or if you'd want to wait that long.
