Grandad plays with Mentos Part #4 Pressure Check

A popular experiment. In the past I tried using Mentos in a sealed Children's novelty drink bottle and came to the conclusion that the reaction stopped when the pressure increased inside the sealed container. Today I tried it with a transparent lemonade bottle and I think I am right.

I cannot answer comments from people who have blocked replies, so if you don't get a reply to your question that may be the reason. It is probably worth reading my video description first because the answer may already be there.

Here are a couple of great demonstrations using Mentos and Soda.

Here are some references to the reaction although none seem to cover putting the top back on to stop the reaction.

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
