Erupting Volcano....

 
all week the boys worked on their volcano
 
******
 
from learning how to make one using papier mache
 
 
to painting it
 
 
to setting it all up, including using some dinosaur props
 
 
we really had to experiment a bit with it to get it to work correctly.
 
first we had to set the bottle up higher inside, since the volcano was so large
 
 
but it wasn't wide enough and the "lava" just flowed inside the volcano, but not up and over.
 
So we fixed it and added a wider bowl to it.
 
 
the coloring looked really dark in the bowl until we added the soda and vinegar
 
 
the 'second' time it flowed correctly....
 

 
but the kids wanted it to be a brighter color, not light orange.
 
so we added more red food coloring to it
 
 
and did it again
 
this time it was perfect!
 


 
the boys were tickled to pieces
 
they wanted to do again, but I ran out of vinegar.

 
 
this was such a fun project for them to do.
 
easy too!
 
for the 'eruption'
 
all you need is a few drops of dish soap (to make it foamy)
food coloring
baking soda
vinegar
 
 
They plan on doing it again, once I buy the vinegar...I see lots of begging and potential bribing in the future.  ;)
