How to make an ocean in a bottle: what you'll need

What you’ll need:

Clean clear bottle with lid

Blue food colouring

Funnel

Vegetable oil or baby oil

Small floating objects (test them first in a cup of water to make sure they float!)

Step 1

How to make an ocean in a bottle

Carefully fill half the bottle with water.

Step 2

Add a few drops of blue food colouring.

Step 3

Slowly add the oil using the funnel, until the bottle is full. The oil won’t mix with the water but will rest on top!

Step 4

Fill your mini ocean with small floating objects shaped like fish, seaweed or whatever your fancy – get creative! They’ll drift down through the oil and rest on the surface of the blue water.

Step 5

Screw the lid on really tightly and gently tip the bottle back and forth to form strange slow-motion waves. It looks really cool!

WHY IT WORKS…

The oil β€˜floats’ on the water, because it is less dense. The two fluids won’t mix together, even if you shake the bottle!
