Pencil Sharpener Youtube Some pencil sharpeners are made of elementary magnesium. they can be set on fire using a gas torch. a bright white flame can be observed. Hi, and welcome to my chemistry channel! here you will find videos containing demonstrations of a variety of chemistry experiments. take a look around, i hope you will enjoy my videos.

Burning pencil sharpeners made of magnesium can be ignited, and burn as bright as a flare!. With most metal pencil sharpeners tend to be made from magnesium so they can be used mutable ways. the sharpener can be used how it was intended however instead of putting a pencil into it we put in a stick. A pencil is sharpened at both ends and crocodile clips attached at each end. these are connected to a low voltage power supply. the voltage is increased and the wooden casing quickly starts to produce copious amounts of smoke and the wood soon ignites.

An attempt was made to verify the hypothesis that pencil sharpeners are manufactured from magnesium metal. test subjects were exposed to a high temperature flame, in an attempt to ignite them. The sharpener continues to burn for another 30 seconds or so, leaving just a white powder of magnesium oxide behind. technically the metal doesn't burn, but rather rapidly corrodes. this activity clearly demonstrates how much energy is stored in magnesium (similarly aluminium). Eventually the wood around the pencil reaches its ignition point and burns away to reveal the red hot graphite glowing beneath, thus showing both the conductivity and unusually high melting point of graphite.
