Ketchup and Baking Soda Volcano

Ketchup and Baking Soda Volcano The acetic acid in ketchup reacts with baking soda to produce an extra-special type of lava for a chemical volcano. This non-toxic volcano recipe is sure to please! Ketchup Baking Soda Volcano Materials small container (I used an empty travel-size bottle.)volcano (You can mold it from clay or use a cardboard form.)ketchupbaking sodaliquid dishwashing soap (optional)water (optional) Make the Volcano Erupt This is really easy! Swirl together a squirt of dishwashing detergent (if you want foamy orange lava), ketchup, and enough water to achieve the desired thickness. When you are ready to start the eruption, add baking soda. Alternatively, you could mix together the baking soda, detergent, and water. Add the ketchup when youre ready for the eruption.The lava erupts slowly and steadily, rather than forcefully, so this is a nice volcano to make if you want a longer-lasting eruption. How the Volcano Works The ketchup contains vinegar, which is dilute acetic acid. The acetic acid reacts with the baking soda to produce carbon dioxide gas. The gas bubbles expand and rise through the liquid, bubbling out the ketchup.
