Make Models of Organic Chemistry Molecules
You may be studying organic chemistry, or just do it for fun. Whatever your needs, it'll always be good to have some molecular models at hand; even better because you can rearrange them to make different molecules.
Do you want to show your students or kids a fun experiment that is safe, easy to clean up after, and yields really drastic results? Well, with a little bit of milk and vinegar, you can create a material similar to plastic in minutes.
