Lava Lamp Experiment

We are really enjoying our work in Science and we wanted to share our recent experiment with you. We could try it at home!
Experiment #3 -Lava Lamp
Equipment.
You need:
*a clear drinking glass or jar
*1/4 cup of cooking oil
*3/4 cup of water
*1 teaspoon of food colouring
*1 teaspoon of salt 
Step 1: Measure water
Step 2. Place water into the jar.
Step 3. Add the oil to the jar.
The oil will float on top.
The oil is lighter that the water.
Step 4. Add the food colouring. We found that the red colour worked the best.
Step 5. Add the salt.
The salt pushes the oil down and then it bubbles back up to the top.
We tried the experiment again with blue food colouring.
When we mixed the colours it turned purple which made the bubbles hard to see.
Next week we are starting our Super Scientist groups.
Keep a look out!
