Leave the kiddos at home for this evening of all things spicy and explosive. Science demonstrations will light up the museum with "cloud-splosions" and flares, and a live ice carving activity will cool things down if you work up a sweat. In the Empirical Theater, put on your thinking cap to learn more about climate change and Cascades volcanoes from local science experts, then snag some spicy snacks from local food and hot sauce vendors like Fire on the Mountain, Choi's Kimchi, and Secret Aardvark. Is it hot in here?
