2day’s How-To: Make Plasma in Microwave
|

Here’s a video showing you how to make plasma in your microwave, this is a simple and easier way to create the effect, just by a single grape (rum and coke optional). Plasma usually takes the form of neutral gas-like clouds or charged ion beams, but can be also dust and grains which called the dusty plasmas.

Alkali Metal + Water = Explosion
|
|
Richard Hammond is showing us why we should never mix alkali metals with water, e.g. Rubidium. Rubidium is the second most electropositive of the stable alkaline elements and liquefies at high ambient temperature (102.7 F = 39.3 C). Like other group 1 elements this metal reacts violently in water which can cause fires. In the video, you will see they do the experiment. Watch the video…
