Water – Ocean In A Bottle & Lava Lamp

WHAT YOU NEED

  • Plastic Bottle
  • Water
  • Cooking oil
  • Blue food colouring
  • A funnel

Instructions
1. Using the funnel fill the plastic bottle about one third full with water.
2. Add a few drops of food colouring to colour the water blue giving the sea effect
3. Using the funnel again fill the bottle with the oil.
4. Close the lid tightly on the bottle and turn the bottle on its side.
5. If you rock the bottle from side to side you can create a wave like motion of the water… like this, looking just like a little ocean in a bottle.

To convert into a lava lamp

6. To turn your ocean in a bottle into a lava lamp you just need to stand it upright.
7. Break an effervescent tablet three or four piece and add one or two pieces to the bottle. (But make sure you get permission from a grown up first)
8. Close the lid, not too tight and watch what happens
