This reaction is well known for the sound it makes (see video below).

Nitrous oxide (laughing gas) and carbon disulphide (toxic, smelly) combust to form nitrogen, sulfur and carbon dioxide.

 Postcards From Google Earth

“The images are screenshots from Google Earth. They are glitches that occur when the 2d satellite imagery and 3d terrain don’t line up quite right, or structures such as bridges get projected down onto the terrain below, creating fabulous and unintentional distortions”- Clement Valla

I began to realize how important it was to be an enthusiast in life. If you are interested in something, no matter what it is, go at it full speed ahead. Embrace it with both arms, hug it, love it and above all become passionate about it. Lukewarm is no good. Hot is no good, either. White hot and passionate is the only thing to be.
