Wow, what an exciting afternoon, spent at The Ladies College in the company of Dr Harrison.
We explored nitrogen and what happens when liquid nitrogen meets air, which is 220 degrees hotter than this liquid. We also learnt what would happen if our hands were placed in this dangerous substance. The flowers were a great hit 😉 and the reversible balloon!
Another favourite gas we investigated was oxygen; we even had a go at making oxygen like our fellow plants!! A messy experiment, but nether the less we did it.
