But I had just seen this science experiment for little ones about an ocean in a bottle and it seemed a perfect moment.
You put water in a bottle, add food coloring to make it the color of the ocean (Maddie was a big fan of this this part!) Maddie had a great time showing her daddy all about it.
She showed him how the oil just sits on top.
And how if you make lots of waves, the oil and water still don't mix. So ultimately, we learned about the Exxon Valdez oil spill. But it was a pretty fun project.
