What's new here?

Erupting volcanos are a staple of many science fairs and school demonstrations. Plus they can be fun to do at home as well. But making the volcano canbe a bit frustrating. Either your make your own volcano with lots of Plaster-of-Paris and the mess caused by it, or a you buy a kit where you make a volcano with Plaster-of-Paris around a framework, or you have a pre-mold that ‘erupts’ using a squeeze bulb rather than a more interesting chemical reaction of vinegar & baking soda.

To help resolve this, the folks ar the Plasteel Corporation developed the Smoothfoam Mega Volcano:


The Smoothfoam Mega Volcano is much larger than most other volcano kits, standing 10.5″ across and and impressive 10.5″ tall.  The volcano is made from expandable Polystyrene foam. It comes out of the box in 3 unpainted pieces.


These pieces assemble and disassemble easily. So once you are done clean-up is a breeze and the Mega Volcano can be used again and again.

The pieces come unpainted so kids can enjoy painting the volcano with the included acrylic paints, first painting it black and then adding details with the yellow, orange and red colors.


To erupt the volcano, you will need some household items that are not included in the kit:

  • Vinegar
  • Baking Soda
  • Red food coloring
  • Dish soap
  • empty soda or water bottle (12-20 oz)
  • Measuring cup
  • Measuring spoon
  • Small funnel (optional)
  • Tray ( for catching the eruptions

Set up for an eruption (wait for the paint to dry first, please) involves putting baking soda into the plastic bottle, opening the volcano and inserting the bottle:


Then, mix the food coloring,vinegar & soap per the volcano instructions. Pour the mixture into the volcano and watch the eruption!



The Smoothfoam Mega Volcano may be more expensive than you average volcano kit, but it can be used again and again. Clean-up and disassembly are easy and the volcano stores well when not in use.
