walt: description of how volcano-prosses
i made my volcano by slowly paper machining. over a bottle it took a lot of time but i got there.
vinegar-acid
baking soda-base
the eruption was a fail there was no baking soda in mine
i saw no bubbles just water coloured i stuck finger in it to make it looked like it exploded
i would add baking soda
