When I visited Montana This Morning on the local CBS Affiliate (KTVQ2) I didn't want to just talk about the Yellowstone Supervolcano, I wanted to help simulate it. So, I brought along my ping pong ball cannons. Watch the video to learn about the History special, produced by Grizzly Creek Films, that I hosted and how to make a handheld ping pong ball cannon!
