Tree by the sea

The Unschooling life of Barney & Hebe

Exploding volcano project!!!

To make a paper mache volcano island you will need:

  • 1 plastic drinks bottle
  • some news papers
  • pva glue mixed with water, 2 parts pva-1 part water
  • a tray or shoe box or something to build your volcano island in
  • a selection of volcano island colored paints -green,brown,grey,blue ect.
    We started by ripping up lots of newspaper and mixing it into our pva glue/water mixture untill we made a thick paper pulp. You want this mixture to be moist and sticky but not runny. This pulp can be made in advance and left covered over until you need it!

    We covered our empty drinks bottle with our paper pulp and built it up to make a volcano shape.

    Barney and Hebe designed their own sides of the island,by making rocks and bumpy land leading to the sea!

    We made use of the hot sunshine and left the volcano island outside to dry!...Drying time actually took a week or more!

     For this explosive experiment you will need:

  • vinegar( we used the vinegar out of pickled onion jar(peeew) because we had run out of regular vinegar)
  • borax or baking soda
  • red food coloring.
    poor in the borax/baking soda and then poor in the vinegar(mixed with red food coloring) and wait for the fizzing bubbling frothy explosion!!!!!

    pour  the borax/baking soda into the bottle and then pour in the vinegar(mixed with red food coloring) and wait for the fizzing bubbling frothy explosion!!!!!

    The kids were so excited and wanted to do it over and over!!!

    eventually we ran out of vinegar so the kids tipped their island up to get all the vinegar back into the jug and start again....I must say this was so fun and as you can see ,a real hit with the kids!!
