                        Science road show
Yesterday my class  went to the Science road show. When we were there we learnt lots of new things like example there  were two bars and there was a rolling pin and a coconut shape thing. The strange   
thing was that they both went down the two bars but the coconut shape one went up as well and the rolling pin only went down.because it was an illusions I learnt a lot of  new things and had a really good time.
