Science roadshow

At the science roadshow I learnt a lot of things. I learnt that liquid nitrogen is a powerful and magnificent ice.

Furthermore, at the science roadshow I also learnt that dry ice can make mist. Next, we went to explore stuff and I saw this light prop and it looked hard to figure it out but I kept on trying to make the light prop glow, then I tried one last time and the light prop glowed. After that I figured out the marble experiment, first I tried a marble and it went straight but when I tried a the martel ball it carved. I learnt about physical and chemical. Physical is when something is boiling just like gas.

Finally, we went back to school.
