I have to make a science working model on any topic. What should I make and how?
Volcano Model
Ingredients
1.Warm water
2. Baking soda
3. Liquid dishwashing detergent
4. Vinegar to make the lava for your volcano. Y
You can color the lava by adding food coloring or powdered drink mix.
To cause an eruption, fill the bottle most of the way full with warm water. Warm water produces a better eruption than cold water because the higher temperature increases the rate of the chemical reaction that makes the lava. Add a squirt of dishwashing liquid, some food coloring to color your lava, and a few spoonfuls of baking soda. When you're ready to start the eruption, pour vinegar into the volcano.
Prepare base for mountain using cardboard, newspaper and all
then follow simple process as explain above.
