How to make a Volcano model without using baking soda and Vinegar?

A volcano is made by a solid that turns into a liquid and has the opportunity to rise through some kind of solid. It helps realism if it includes something like gas, because that is also part of a volcanic eruption.\n\nThere are several great ideas here:http://volcano.und.edu/vwdocs/volc_models/explosive.html

Anhydrous copper sulfate and water would be the easiest two. \n\nYou can buy copper sulfate at any good garden supply shop and most larger hardware stores. The copper sulfate usually sold is hydrated, and is already blue in colour.\n\nYou can make it anhydrous by putting it the oven, uncovered on a sheet of tin foil at 120oC or hotter. You will know when it has become anhydrous beause it goes white. This is quite safe to do in your kitchen oven, all you are doing is driving off the water. No nasty fumes or residues are produced.\n\nStore the crystals in an airtight jar to stop them absorbing water from the air. When you are ready add some water to a few crystals they will retrun to their original blue colour.\n\nThe other possibility is to manufacture your own cabbage indicator. That will make a bluish purple colour when mixed with baking soda. I've included a link with instruction on how to do this.\n\n______\n\nErrata.\n\nThat's what you get for working from memory. Copper sulfate will only partly dehydrate at 120oc. You will need to set your oven to 160oC or higher to create anhydrous copper sulfate.

One of my favorites is making carbon dioxide. I have used this with my nephews and nieces.\n\nYou will need water glass 6 to 8 oz\nbaking soda\nvinegar\nmatches\n\nput a couple teaspoons of baking soda into the glass (you don't need an accurate measurement)\npour in vinegar until the glass is about 1/2 full\nuse the time it fizzes to explain about carbon dioxide (do a little research for this part)\nlight a match and insert the lighted end into the glass (it will go out) or\nlight a match and very carefully tip the glass, pouring the gas over the match, it will go out. Be careful not to spill out the liquid. You won't hurt anything if you do, it just spoils the effect.

You know, I answered exactly the same question not 2 days ago.\n\nAnhydrous copper sulfate and water would be the easiest two. \n\nYou can buy copper sulfate at any good garden supply shop and most larger hardware stores.

I'm not sure about anything realistic or that they can learn from... but a fun activity, if that's all you want - it to get some old wire-mesh or anything else that'll make a good surface, shape it into an open-topped cone with something just inside the top of the cone that will hold a test-tube or small container just below the top of the peak (eg you could shape some wire to hold it, or perhaps tape or somehow else fix a tube in there). You can then build up your own volcano with papier mache, when it's dry paint it (eg white snow near the tip, dark green for trees lower down, or whatever you prefer). You then mix up some white vinegar with some red food colouring to represent lava, pour a little in the bottom of the container, and when you're ready, add a spoonful of baking soda or so to it! It fizzes up and runs down the sides of the volcano...\n\nThis is a pretty full-on project to make I suppose - you may just want to make one and allow the kids to play with it! It's not exactly realistic, but it's fun...

Easy!\nStir the mixture into water. Sand sinks. Styrofoam floats.\nScoop the Styrofoam off the water surface with a strainer.\nPour off the water.

first vapour it all if there is no rubber monomer vaporize then try a distilation tower with hysys if u want i can simulate it for u?

Baking soda is sodium bicarbonate -- NaHCO3.\n\nIf you burned it, it would generate carbon dioxide (gas), water (vapor), and sodium oxide (solid residue).\n\nShould be no big deal.  Enjoy your bead making!

Well i remember I did a research on hidroelectric plants. And the good thing is you can make aworking model using some water and a bicycle generator hooked to a small light bulb (holiday decoration ones or others like that) also any kind of research that involves things the evaluator can actually see working and moving is always a plus. Just stay away from volcanoes, while they ARE very interesting, its been done quite a few times. Hot air ballons are cool, some china paper glued to make the ballon and a aluminum plate with a candle to keep the air warm (you inflate it with a hair dryer) and you have yourself a working model, plus you have all the data refering how hot air is less dense than cold air etc...there are a lot of cool things you can do out ther and believe me Internet IS going to be VERY useful

WEll... I was going to go to the trouble of giving you a real answer.   But since I see its already been answered I'll just say... \n\nDo it by trial... pour one milk jug of water into it at a time.\n\nYou could use milk too but that would be expensive and smell horrible

I have got some sites for science projects on volcanoes.\n\nhttp://www.all-science-fair-projects.com/project815_39.html\n\nThis is another project for making a volcano with a purchased kit.\n\nhttp://www.hobbytron.com/make-volcano-model-science-project-experiment.html\n\nThis is another volcano science project.\n\nhttp://www.scienceproject.com/projects/intro/primary/PX001.asp

Well of course.........Chili Volcano's!!!\n\nFilling yet inexpensive - make your favourite chili recipe - buy hamburger -  (on sale) fry up with onions and add either a can of tomato soup (may need a little water if using soup base) as your base or tomato sauce. and add a can of red kidney beans - then add your spices.   Let simmer to blend.    Peel and boil up your taters.  Once taters are tender - drain and add a little milk and mash.  \nIn center of plate have a little mountain of taters and then put your chili over it - there ya go - a Chili Volcano\nHey - when I was a single parent and needed to make *ends meet* - it was a way to fill little tummy's and get my son to eat his taters and he thought it was neat.  He's now 32 and still makes Chili Volcano's  hehehe\nPS  - my chili today has evolved from this basic recipe - but you asked for cheap - but we still serve it Volcano style sometimes.

Put some vinegar in a small soda bottle.  Use a straw with an end of it cut so it is like a spoon to put baking soda in a balloon.  Carefully place the end of the balloon on the top of the soda bottle working around the grooves of the bottle, but not dumping the baking soda in yet.  When you are ready, lift the balloon up so that the baking soda dumps into the vinegar, and watch the balloon inflate.  You just showed a chemical reaction.

Here's a clever way to make an artificial volcano. \n\nMaterials:\n1.flour 2. water 3.food colorings-red and yellow 3. a small plate 3.baking powder 4.vinegar 5.pencil \n\nExperiment:\nFirst mix the plain flour in a little flour,make it into a dough then make it in he shape of a small mountain and keep it on the small plate then make a hole by inserting the pencil into the top center of the mountain and allow it to dry ,after it dries remove the pencil. You will see that it is like a mountain with a volcano hole. Put baking powder into the hole along with the red and yellow food colorings and then gently pour a little vinegar you will soon see that vinegar and baking powder react eject out from the hole and that is along with the color which looks like the volcano erupting from the mountain. \n\nData and Observations:\nWhen an acid reacts with a base effervescence is formed and a salt is formed.
