For this video, I am going to be making some laughing gas, aka nitrous oxide. Then, I'll be using it to carry out the classic Barking Dog experiment. To make it, I'll be using the safer method, which uses sodium nitrite and hydroxylamine hydrochloride. The typical industrial process, using ammonium nitrate, can be quite dangerous.

This video has been a long time coming and I am glad that I could finally release it. I have been promising people this forever!
