My kids love to make "volcanos" simply using a bottle, baking soda and vinegar. You can get a bit more complicated if you wish but I like to keep things simple.
To make a volcano:
Materials: One short bottle (not too tall or the baking soda "lava" won't flow over the top), 2 tbs of baking soda, few drops dish detergent, vinegar, towels to clean up the mess
Put a few drops of dish detergent at the bottom of the bottle
Put in about two tablespoons of baking soda into the bottle
Slowly pour in the vinegar and watch the volcano erupt!
The baking soda and vinegar combine to produce carbonic acid which breaks apart (causing all the fizzing) into water and carbon dioxide.
• If you wish to get fancy, papier-mâché the bottle with a mixture of newspaper and glue) or wrap the bottle in foil to make it look like a volcano.

Cure all camping needs
Baking soda is a must-have for your next camping trip. It's a dish-washer, pot-scrubber, hand-cleanser, deodorant, toothpaste, and fire extinguisher, and has many other uses.
Baking soda can help in the initial handling of minor grease or electrical kitchen fires, because when baking soda is heated, it gives off carbon dioxide, which helps to smother the flames. For small cooking fires (frying pans, broilers, ovens, grills), turn off the gas or electricity if you can safely do so. Stand back and throw handfuls of baking soda at the base of the flame to help put out the fire — and call the fire department just to be safe.
