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.  ;)
