we did this in chemistry class. for all of you people who are wondering why they did this, the point is to turn the zinc/copper into brass. you can watch it change colors from copper-colored (obviously) into yellowish with red/purple hues. our penny dripped on the lab bench... it was SO COOL!!

@salevidebay Actually it's not legal to melt a ton of pennies if you have them laying around. That is a big ole federal offense. If you didn't know; the value of the materials in a penny is worth more than a penny now. On the other hand, you can destroy currency if it is for educational purposes.

You can destroy (paper or metal) currency if it is yours. It is not illegal. But do not expect to be repaid for the destroyed money. Source: US Bureau of Printing and Engraving Fort Worth. So if you want to melt 100 penny s that you have laying around go for it. Its yours.

fighting inflation is illegal...they are like little ingots tho :)

Yes and no, It is illegal to destory currency. However it is Iegal to destory currency for the purpose of education. As for people whining about inflaction and other such non-sense, heres a fun fact a penny costs more to make than its worth in its currency value.
oh yeah? they have a hot-line for penny burners?

The color of the flame is directly proportional to the temperature of the flame. heat releases light energy with frequency directly proportional to temperature, or wavelength inversely proportional to temperature. Blue has a high frequency/small wavelength, thus shows a higher temperature.
red and yellow flame are colder than the blue at the base.
