Watch this science video tutorial from Nurd Rage on how to restore silver with electrochemistry. You can restore old silver with aluminum foil or a battery by simple electrochemistry. Old silver is often tarnished by a thin layer of silver sulfide that appears as a brown colo ...more
If you want to make some electrodes for electrochemistry, titanium strips are the way to go. It's rather interesting metal, and it's really hard, but can be cut with standard metalworking tools. Titanium filings are highly flammable, just like iron filings. But not everything ...more
If you've been following the news lately, you've probably heard of the word "vitriol" being used as a political weapon, with people like celebrity left-winger Jane Fonda blaming conservatives like Sarah Palin for "vitriolic" attacks on Democrats and the "violence-provoking rhe ...more
Michael Faraday was an English chemist and physicist - a bona fide electromagnetism and electrochemistry genius. Without him, men couldn't walk on live electrical wires. Wait, what? In the Smithsonian IMAX documentary Straight Up: Helicopters in Action, helicopter pilots perf ...more
This is a great school project or weekend fun. Grow some silver crystals that you can see under a microscope! Use the princples of electrochemistry to create crystals out of silver metal, and watch them grow right before your eyes.
