In Te Maunga this week we had a visit from the Northland Science Roadshow. We had three activities and the first one we tested water. We used chlorine to make the water blue. Chlorine is used in pools so the yucky stuff dies and no one gets sick. The more chlorine you put in the darker it gets. The good thing is, at the end we got lollies (yay). The next activity was the most interesting because we got these glasses that had 530 lines per mm and the glasses made everything RAINBOW. The last activity was launching rockets and we had to use air and fire and it did NOT launch that far.
