Is there a relatively safe alternative to vinegar and baking soda for chemical reaction volcanoes?
My brother is working on a paper mache volcano experiment for school, and I figured that the instructables community has come up with something a little more creative than just vinegar and baking soda. When I say relatively safe I mean something that doesn’t emit poisonous gasses or toxic waste. Thanks for any help. Update: I’m not worried about the safety of vinegar and baking soda, I added a safety request because I was almost very stupid mixing chemicals without checking about results. I almost created a gas used to exterminate people. There is no need to lecture me on how stupid this was, I already know.
