Working Volcano Exhibit
See a short movie of this volcano model exploding!
What You Need:
What you do:
Paper towels will be handy to have on hand for clean-ups.
If you want to go simpler still you can just use a container like a large pop bottle instead of a model volcano.
Then use same directions as for the above model volcano – In a jug or large jar (with lid for transport), mix about 10 drops of red food dye into about a pint of vinegar. This should be good for several volcanic “eruptions”.
Place + or – half cup of baking soda into your volcano container – the pop bottle
Pour about 2 tablespoons of your red vinegar into the container
Important: Make sure to have a large catch container like a deep tray or large pan underneath your volcano container -pop bottle, and paper towels on hand for clean-ups.
Note: You might want to practice your volcano eruptions at home, maybe outside, to find out beforehand how messy this might be and what size catch-container you will need to use.
Also be sure to create a poster with your exhibit’s information. To know more about setting up for a science fair and what to write on your poster and illustrations to include go to the science fair and site visitor ideas pages.
