What materials are needed for coke and Mentos?

To make a Coke (or any other carbonated beverage really) and Mentos geyser fountain, you will need the following:

- Mentos mints

- Diet Coke or any other carbonated beverage (works best with diet drinks because they contain more carbon dioxide)

- A wide-mouth bottle of Coca-Cola (2-liter bottle works best, but smaller sizes will work too)

- A safe and clear area to conduct the experiment

- A camera to capture the action (optional)

Additional Items that may come in handy:

- A funnel (to help guide the Mentos into the bottle if needed)

- Safety glasses (to protect your eyes)

- A large tray or container (to catch any spills or overflow)

- A towel or cloth (in case you need to quickly clean up any spills)

- A stopwatch or timer (optional, to measure how long the fountain lasts)
