How To Make A Volcano Using Simple Items And Ingredients?

Well I used :
Vinegar

clay

bottle

baking soda

food coloring

flour

But you don't have to use it all I used all of it to make mine look good.LoL:)

Dollar Stores, Family Dollar, Dollar Tree are cheap places for the add ons...

Great Fun for the Entire Family! The Eruption is Awesome!
Volcanoes are some of the most fascinating natural wonders in the world. It is no small wonder that students everywhere choose this molten wonder for their science project each year. Building a homemade volcano is actually quite simple, and does make a great science project when done correctly. Here is some quick easy steps to building a homemade volcano:

Supplies:

--Sand

--Small square sandbox or square plywood board

--Teaspoon of baking soda

--Four drops of red food coloring or dye

--Small plastic cup

--Vinegar

--Any accessories you can build to add to the effect (things like trees, a lake, or bushes, etc...)

The first thing to do for your homemade volcano science project is to pile the sand in the sandbox or on top of the plywood. If you are using a piece of plywood for the base, be sure to put up some type of borders to keep the sand in place. If you do not have sand, you may also use dirt or plaster. Sand is definitely the best option if available.

Next, you will want to dig out a hole in the center of the volcano to insert the plastic cup into. Take your water bottle and keep the sand wet while forming these things. It makes the sand easier to form. Make sure that you dig some ridges into the sides of the volcano for special effects. Also, dig trenches throughout the science project for the lava to run through.

The next step is to add the baking soda to the plastic cup within the volcano. Once you have done this, add three or four drops of red food coloring. This red food coloring will become molten red lava when you add the vinegar to the mix. The effect is spectacular.

At this point you are ready for the science project to come to life. As soon as you are ready for the eruption, go ahead and add the vinegar. The volcano will come bubbling to life, and you will have one heck of a science project. Red, flowing lava will work its way out of the volcano and down the sides through the trenches. Make absolutely certain that you take the time to fix up the project with miniature trees, bushes, and even some lakes. It truly adds to the realism of your homemade volcano science project.

To make an erupting volcano you will need:

• A volcano - Talk to an art teacher about making a volcano out of paper mache or plaster. If you're in a hurry to make your volcano, use a mound of dirt outside.
  
• A container that 35mm film comes in.
  
• Red and yellow food coloring (optional)
  
• Vinegar
  
• Liquid dish washing soap

What to do:

1. Go outside
   
2. Put the film canister into the volcano at the top
   
3. Add two spoonfuls of baking soda
   
4. Add about a spoonful of soap
   
5. Add about 3 drops of the red and yellow food coloring
   
   Now for the eruption!:
   
   
6. Add about an ounce of the vinegar into the container and watch what happens.

• Paper Mache or Plaster. One can also use a mound of dirt.
• A container that 35mm film comes in.
• Brown, red, green paint and brush.
• Vinegar
• Liquid dish washing soap or baking soda

Baking soda & vinegar. Maybe a little dry ice for extra effect. You can build the structure from paper machete or spray foam insulation. Experiment with different amounts of the vinegar and baking soda to get the volume and duration of eruption you require. If you also use the dry ice have it in water in a separate container from the vinegar & soda.

Backing soda and vinegar and food coloring in a can with dirt staked around it!
That will work!

You need limited things to make an edible volcano.  But first you need to know what an edible volcano is in order to make it. This is my anwser.

I'm making a model volcano and I wanted to now what I need

I used
great stuff
diet coke
mint mentos
wood
paint

Ask Some one to tell you!
