Science – Green Octahedron Blogging

In the clip, a copper tree turns into a silver covered tree, which looks like a snow covered tree.

For those thinking of replicating the experiment, be prepared to fork out about $ 100.

You can do a much cheaper experiment (less than $ 1). Dip an iron nail into a copper sulphate solution. The iron nail will turn into a copper nail, almost immediately!

The copper-iron and copper-silver interaction are examples of reduction and oxidation reactions. Oxidation and reduction reactions make mirrors possible where silver is deposited on glass and copper is deposited on the silver layer.

Thanks for the link Alexander and Anderson.

img_20190110_084639 — Yes, a GREEN Kettle – of course.

I am the proud owner of a CatS61 smartphone, with a FLIR camera. The smartphone does what I need it to do.

Science is about observing nature and, as a friend of mine commented, saying “That’s odd”. I add, “How does that work?”

The people around me need me to have my morning coffee. On the odd occasion, my mind is awake before the coffee, though. I took out my Cat S61 FLIR camera and took photos of the kettle boiling, and yes it is a green kettle.

The photos show the false colour images; showing the relative temperatures of the objects in the room. As the water boils, the kettle’s body also heats up, and the images represent what is happening to the water inside the kettle. The images show the inferred temperature at the cross-hair point.

I used the time lapse facility to capture the image of the water heating process every five seconds and plotted the relationship. The relationship is linear, confirming that the 2000 W kettle element adds a constant amount of energy to the kettle and water every second.
