Big C and the volcano - questacon part II

Our day at Questacon had so many amazing moments that it certainly warrants another post (or two). At the lunch hour presentations on severe weather events, Big C was certainly a star of the show. We shared the 200 seat theater with a few other families and about 170 high school students from Sydney. When the questions about severe weather came up, BigC was often the first to have his hand up and get picked. Only rarely did Dave whisper him the answer in advance. He certainly knew what caused severe weather events and that a tsunami could be caused by an asteroid impacting the Earth. The teenagers were abuzz after Big C's responses.
When they were looking for volunteers for a demonstration to close the show, Big C's hand shot up quickly again. The host chose Big C and he was off and running.

I'll let the video of the event speak for itself.

Big C was delighted and we all left for lunch with huge smiles on our faces.
