Science In A Van

Yesterday,  4/9/13 we saw Science in a Van

                                                            Here is the story...

At 9:15 am in the hall 2 people named Allan and Emily who travel around New Zealand putting on science shows came to Windsor School. First, they put on Sound and Personal Eye Image effects. First they showed us a Stock Whip and tried to break the sound barrier which made a sonic boom which means they tried to break 1225 km. Next they showed us a black and white twirly thing. Emily spun it one way and we looked in the middle and Emily's head shrunk also she spun it the other way and her head seemed to get bigger. It was an optical illusion. Next they were talking about bubbles, mixtures and scientific words. Firstly they were showing us different kinds of bubbles.

Hope you enjoyed it... ta ta.
