Make your own Lava Lamp!
 Materials you will need:
• Water
• Baby Oil or Vegetable Oil
• Food Colouring
• Clear Plastic Bottle with Lid (Small)
Mix some water and baby oil with a few drops of food coloring in a plastic bottle and watch a lava lamp in action.
Steps:
1. Fill the bottle three fourths (3/4) of the way with vegetable oil.
2. Fill the rest of the bottle with coloured water.
3. Close the lid tightly.
4. Turn the bottle on its side – watch as the colour moves through the oil in funny shapes and blobs.
Explanation:
The water and the oil do not mix because the water has more density than the oil.
Density with Eggs!
Materials you will need:
• Table Salt
• Two Bowls
• A Tablespoon
• Warm Tap Water
• Two Eggs
• A Friend
Steps:
1. Fill both bowls with warm tap water.
2. Add a few tablespoons of salt to one of the bowls of water and stir it really well, until the salt has dissolved in the water.
3. Carefully place a egg in each bowl.
4. One egg will float and the other will sink.
Which egg floats? Do you know why?
Explanation:
The salt water is heavier than the plain tap water, so the weight of the egg does not have to push away as much water to make space for itself and therefore it floats.
Run Away Pepper!
 Materials you will need:
• A Bowl
• A Dash of Pepper
• Liquid Dish Soap
1. Fill the bowl with water.
2. Sprinkle a dash of pepper in the bowl of water.
3. Add a drop of liquid dish soap.
Explanation:
The pepper scurries away from the soap. This is because the soap breaks the surface tension of the water and the tension on the rest of the water pulls the floating pepper away from the soap.
