Salty Science Experiments!

This morning when I browsed  Pinterest, I found a link for science projects which use salt. Since my grandsons love science projects, I thought I'd check the link and take a look at the "salty" science projects. 

There are eight salt projects, which you will find at this link, and each one uses simple supplies you likely already have in your home. Each project includes simple directions and explains the science behind the project. They look like projects my grandsons will enjoy for sure!

We will be trying them - I think they will enjoy the project with the layers of water the most, but we will see!

Which salty project do you think your grandchildren will enjoy?
