Nitrous oxide film (giggle, giggle)

Well I have made a film about nitrous oxide. This is not a film about people getting high on nitrous oxide. While some of my readers might think that getting as high as a kite on nitrous oxide is funny, I do not share this view.

Nitrous oxide is not a nontoxic gas, it can cause some serious health effects. my trusty copy of the BNF reminds me that it can cause “megaloblastic anaemia” due to an interference with vitamin B12. Operating theater staff who are exposed to nitrous oxide have been found to have lower levels of vitamin B12 in their blood

So I would strongly advise you not to inhale nitrous oxide for fun, if you want fun I would suggest that you read a book or go walk the dog.

Back to the topic of my film. It is a recreation of an experiment which I did as a teenager. A squirt cream can after the cream has been used still contains nitrous oxide. Rather than putting it into the trash I did the following. I filled a sink with water and held the can under water. It is then possible to collect the gas using a water filled glass bottle (or as a teenager I used a pint glass).

If a glowing splint is placed in the gas it will reignite, this is a test which most people associate with oxygen but nitrous oxide will also give a positive result. Please sit back and watch the film.

Disclaimer, while Dr Mark Foreman takes all reasonable care to comment on interesting chemistry and create safe and enjoyable experiments I accept no responsibility for any death, injury, disease, property damage, prosecution, criminal court case, tort, civil court case or other adverse outcome resulting from you trying out an experiment of mine or using any information I provide. All experiments are done at your own risk. If you are not an adult you must consult your parents and/or science teacher before trying an experiment. If you are doubt about your ability to do the experiment in a safe manner then do not attempt it. Also I accept no responsibility if your mum/dad/teacher/policeman/(insert some other authority figure) tells you off for doing the experiment. Also I am not responsible for your moral, social and spiritual wellbeing. Also if you hate the experiment and do not enjoy it or are left with an intense feeling of self disgust then again I am not responsible. If you read this disclaimer or anything else I write and have some adverse reaction to my words such as going insane, laughing yourself to death, pushing your blood pressure through the roof or some other effect then again I accept no responsibility. Also if you use information in my blog to answer an exam question then I offer no warranty to how good the information is. If you take material from my blog and try to pass it off as your own when you hand in your home work then I take no responsibility for you or offer any sympathy when your teacher tells you off (I hope that the teacher is reading this blog also)
