Did this prac this morning with Year 10s while looking at chemical reaction types...

Fake white roses - the kids soaked the rose themselves in UI in Kartell bottles (we told them if they wet them too much the reaction wouldn't work). They dried them & then we used ammonia as the base & 0.1M HCl as the acid. Awesome!
