Expand on this:
Perform your own Mento and Diet Coke experiment. (Come on, you know you want to!)
Purchase several 2-liter bottles of Diet Coke (once is not enough), and a couple rolls of mint Mentos. For more efficient and less sticky delivery, remove a cardboard tube from the middle of a roll of toilet paper. Cut tube lengthwise. Retape tube to fit around a Mento. (Tight enough so the Mentos doesn’t turn, but loose enough so it can slide out the bottom.) In a large outdoor area, open a bottle of Diet Coke, and set it on the ground. Brace with rocks or bricks so it won’t tip over. Place a notecard over the mouth of the bottle. Line up the toilet paper tube with the opening over the notecard. Fill the tube with Mentos. Quickly remove notecard and run away to avoid geyser spray. Repeat.
