Underwater Fireworks!

Science, science and more science! Last week we even made underwater fireworks! Here is what we did - and you can try this at home!

• fill a glass bowl or jar with water
• in a test tube (or little container) put 3 ml of oil, 2 drops of red food colouring and 2 drops of blue food colouring and use a stirrer to mix it together
• gently drip the coloured oil into the water and watch the fireworks begin!

As the coloured drops exploded, they sunk to the bottom!
It looked really cool!

When we looked at the top of the water, you could see large oily blobs floating there.
What we learnt about oil and water with Mrs Thompson has come in really handy!
