In this video we make a chemical thunderstorm in a beaker using manganese heptoxide. I wanted recreate the test tube thunderstorm on a larger scale, adding sound for a more immersive experience. The setup involved using a glass funnel to carefully pour sulfuric acid into ethanol and form a layer of it in the bottom. Sprinkling potassium permanganate into the mix led to the formation of manganese heptoxide that reacted with ethanol and produced display of small explosions, accompanied by popping sounds and flashes of light.

In this video we show you how to levitate pencil lead. In a previous video we showed that pyrolytic graphite was diamagnetic, it was repelled by magnetic field, and that this repulsion was strong enough to levitate it. You can see the previous video here: https://www.youtube.com/watch?v=jyqOTJOJSoU Now pyrolytic graphite is expensive so a cheaper alternative is to use very thin pencil lead. Not all pencil lead works so you need to first test it by placing it on a table and approaching it from the side with a magnet. If the lead moves away, then it's diamagnetic, if it moves toward then it's paramagnetic and can't be used. The pencil lead must also be thin, a very thick pencil lead will be too heavy for the effect to work. ... https://www.youtube.com/watch?v=yeIizmhzPQc
