This is a Thank You card I received after doing a school visit to my eldest daughter’s class in school when she was about 6 or 7, over 15 years ago. I was asked to come to the school for science week and give a talk. I decided to make it a bit more fun and brought some liquid nitrogen and a few other ‘sciencey’ things (to do some experiments). The kids loved it, especially when I pretended to freeze my gloved hand in nitrogen and smashed my ‘frozen finger’ (aka pork sausage) with a hammer! I was treated like royalty afterwards and it reminds me of the fun that science can create.
