safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle. 2. Add 8 drops of your favorite food coloring into the bottle. 3. Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it. 4. In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds. 5. Now the adventure starts! Pour the yeast water mixture into the bottle( a funnel helps here) and watch the foaminess begin!
You will need:
• A clear drinking glass
• 1 / 4 cup vegetable oil
• 1 teaspoon of table salt
• Food coloring( optional)
• Water
Try Some Lava in a Cup
How does it work: So what’ s going on? Of course, it’ s not real lava but it does look a bit like a lava lamp your parents may have had. First of all, the oil floats on top of the water because it is lighter than the water. Since the salt is heavier than oil, it sinks down into the water and takes some oil with it, but then the salt dissolves and back up goes the oil! Pretty cool huh?
How to proceed: Fill the glass about 3 / 4 full of water. Add about 5 drops of food coloring. Slowly pour the vegetable oil into the glass. See how the oil floats on top – cool huh? It gets better. Now the fun part: Sprinkle the salt on top of the oil. Watch blobs of lava move up and down in your glass! If you liked that, add another teaspoon of salt to keep the effect.
