On friday my family went to the powerhouse museum. There was alot of things to do and to look at there.There were spaceships, satellites, robots, engines and experiments that you could do. My favorite thing was the lightening ball. I learnt that you can power stuff by using bikes. I learnt about how it feels in a space ship when there is no gravity because they made a space station turn around and it felt like you were turning around. It made me feel creeped out. The science museum was cool.
