Generate your own electricity with some wire, a magnetic field, and the relative movement between the two of them: Alom Shaha explains electromagnetic induction using this hand-powered – or perhaps more accurately, bacon-sandwich-powered – generator.
Related watching: magnetic fields, probably one of the more awe-inducing subjects on this site.

There are scientific toys and tools that can easily reveal the magnetic fields around a magnet—we've even made this DIY black sand version. But what does it look like when you bounce a powerful neodymium magnet and m...
"The first thing to realize is that when you pickle something you put it into a mixture of salt and vinegar. Salt contains ions, sodium ions, chloride ions, and salt solution is electrically conducting, but it's not v...
To move liquid from one container to another, you may need a siphon, a bent tube with one end that's lower than the first. Suction is one way to get the liquid moving through it, but if you don't have a pump and you d...
How can you fit a bunch of balloon animals into a small container? Add some liquid nitrogen into the mix, as demonstrated in this video by Real Physics Live, the YouTube channel for Texas A&M University's Department o...
Not having access to electricity, life in Ambakivao, Madagascar was dark. A group of grandmothers decided to change that, bringing light to their community by becoming the village’s first solar engineers. With the hel...
In the 1987 miniseries The Ring of Truth: An Inquiry into How We Know What We Know, Philip Morrison proves that a water molecule is composed of two hydrogen (H) atoms & one oxygen (O) atom with a simple demonstration....
Can you power an electric supercar with lemon-power? It depends on the lemon-power. In the video above, science YouTuber and former NASA JPL engineer Mark Rober attempts to fill a 48-kilowatt-hour battery with electri...
If you're ever at a beach with some black sand in the mix, run a magnet through the sand to see if the black sand sticks. Exploratorium educator Ken Finn demonstrates this experiment with a magnet and a plastic cup at...
Build. Observe. Play in the sand and dirt. Making your own easy-to-build squeeze box is fun for lots of different reasons, including educational ones. This Science Snacks video with Eric Muller from The Exploratorium ...
What happens to a cluster of grapes when it's in between two large, very strong and potentially dangerous neodymium magnets as they collide? Science presenter Kevin Delaney and his team demonstrate the power of these ...
