Make waves with this mesmerising mini seascape by recycling an old bottle!
HOW TO MAKE OCEAN IN A BOTTLE
GRAB THESE MATERIALS…
A clean transparent bottle with lid
Blue food colouring
Funnel
Vegetable oil or baby oil
Small floating sea creatures
START BY…
Taking the lid off of your bottle and filling your bottle up half way with cold water.
NEXT YOU…
Add some of the blue food colouring to give it that ocean colour. Be careful not to add too much as you don't want to make the water too dark.
THEN…
Fit your funnel into the bottle neck and carefully fill up the rest of your bottle using the oil. Here's the cool bit: the oil won't mix with the water and instead, will rest on top of it!
AFTER THAT..
Now for the (extra) fun part: start to add your sea creatures. Whether they're mermaids, stars for starfish or whatever else you can find. They should come up to the surface and sit on the oil.
ALMOST THERE…
Put your lid back on and make sure it's super secure, then give your bottle a good shake.
INTERESTING FACT
Oil and water don't mix and that's how you can keep your sea creatures afloat. Seeing how the elements react to each other is a great opportunity to share some sciencey wisdom.
