Answer 2

Make Pulp
-you will need a LOT of newspaper!
-rip newspaper into a zillion little squares/pieces
-let sit in a bowl of water overnight
-the next day, squeeze completely dry
-mix in glue
-make a volcano shape, leaving a hole at the top
-put a cup in the hole at the top so that when you pour the vinegar and baking soda, it won't seep into the paper.
Color
-when the pulp is all dry, you may paint it if you wish
Eruption
-put baking soda at the bottom of the cup and pour vinegar (it looks cooler if you dye the vinegar red/orange)
---an alternative to vinegar and baking soda is 7-up or sprite, and then drop a mentos candy in it! it's way cooler and it shoots further, but vinegar+baking soda is better for indoors.

Answer 3

Easy. You use a bottle hot gun glue it to center of an old cookie sheet or heavy card board base. Build around the bottle to look like a mountain with paper mache (paint, varnish or polyurethane it) or get a can of that "great stuff" you know that expanding foam (find it in the hardware store). build your mountain up to the top of the bottle but leave the mouth of it open and clear.Work on this outside, can be messy.
When this is dry. Use a funnel to put the baking soda in the bottle then add the vinegar......INSTANT LAVA!!!

Answer 4

add something acidic like vinegar. Make a paper mache volcano with a hole in the middle and put baking soda in it and then just add vinegar i think.

Answer 5
