Antifreeze and Molten Copper Make a Big Fire

Why pour molten copper in antifreeze? Why ask silly questions? This backyard scientist has too much time and scrap metal on his hand, but he makes a pretty cool video. With a 2500 °F furnace, he's got liquid metal in no time. As soon as he drops it in the green coolant there's fire everywhere. Once it's all cool he's left with a pretty neat little paperweight.
