For this week's Science Saturday we decided to do an "ocean in a bottle". I had seen a few examples on Pinterest and thought that it looked easy and stunning.
We started with the items we needed. Oil, food colouring, a bottle and water. The instructions said to fill the bottle 1/3 full.
Then add some food colouring.
So far, so good.
Then we were suppose to put in the oil.
We shook it up and tiny bubbles formed.
But it didn't really look very dramatic.
So we thought that maybe we didn't use enough oil. We tried again with more oil.
This one looked better but the oil was very yellow.
It was interesting to see it separate again once we had mixed it up.
The children didn't think that it looked like an ocean.
