Today we are going to tell you what this second experiment is about: making “plastic” from milk. Originally we heated the milk without allowing it to boil and then added a tablespoon of vinegar and stirred the mixture. Then, we observed that it began to solidify, forming small lumps. …

Chemistry in the Bath with Effervescent Bombs

Today we continue with chemistry experiments: effervescent reaction, which we began in Chemistry Iniciation with Effervescent Reactions. In this case it is also about a fun activity, perfect for holiday time spent at home with the family. We will need citric acid (sold in specialized drugstores), bicarbonate of soda, oil (can be olive or flavored bath oil), and a few drops of liquid dye (or better yet, powder). Mix one …

We recall that a chemical reaction is a process by which one or more substances (reactants) are transformed into others with different properties (products). In our experiment we use vinegar and baking soda as reactants, along with some additional material: a glass jar, a plastic bottle …
