Today was more science experiments. It was a bit windy for exploding rockets but we just about managed the volcano experiment.
I got the ingredients ready. Volcano, spoon, bicarb, vinegar and sand for effect.
We took them outside, I filled the volcano with neat vinegar.
They made the 'island' of sand and water and rocks from the patio.
Then I quickly poured in the tsp of bicarb and screwed the lid on.
We had a magma explosion!!!
A stream of magma but the top didn't quite explode off...
Then the pressure eased a bit
and we had a major lava flow.... awesome!!!
Good thing it was an uninhabited island...
