Copper is an algacide. When placed in water the copper penny or any other small piece of copper will start to act with the oxygen in the water and oxidise (the copper turning blue green in the process). The increased level of copper in the water retards or prevents the growth of algae in the vase. Works best in clear glass vases where algal growth is normally high.

Would a spiral vase work as well as a bud vase for holding single stems of flowers?
Spiral vases should work just as well as a bud vase especially with single stem flowers.
Does a copper penny work to draw out poinson or stingers?
I doubt it.
What is the antidote for copper?
where did you get soluble copper? p.s. if you swallowed a penny just wait a few days... everything will, um, work out.
How does Pascal's vase work?
it has something to do with static pressure
What flowers work well together?
flowers work together by collecting pollen and sperm
How do we keep roses fresh?
You can use aspirin, a penny, hairspray, bleach, or the florist packet that comes with flowers to keep cut flowers fresh. They all work pretty well. Also, using mouthwash works great. My class did a test on this and putting protein powder and toothpaste doesn't work at all.
Why is copper very important in the area of nonferrous alloy production?
Copper is very important for computers to work. It is used in building the integrated circuits, chips and the printed circuit boards of the computer alone. The IBM (International Business Machines) planned to use copper in computer chips instead of aluminum because this will make the computers cheaper and also allow the computers to make faster calculations. Copper is also used as a conductor of electricity. Nearly all electrical devices rely on copper wiring because copper is inexpensive and highly conductive. The reason why copper is a good conductor is because there are lots of free electrons that can carry the flowing current well. Copper is also uses in currency. The American penny used to be 95% copper with 5% either being zinc or bronze. At one point the penny had changed into zinc-plated steel, but because the steel was magnetic it kept getting stuck in vending machines. So then they changed the penny's core to zinc and coated it with copper.
Is a penny metallic?
A penny is made from zinc coated with copper. Copper is a reddish brown nonferrous mineral which has been used for thousands of years by many cultures. The metal is closely related with silver and gold, with many properties being shared among these metals. Modern life has a number of applications for copper, ranging from coins to pigments, and demand for copper remains high, especially in industrialized nations. Many consumers interact with copper in various forms on a daily basis. Archaeological evidence suggests that copper is among the earliest metals used by humans. Numerous digs all over the world indicate that copper was used to make utensils, jewelry, and weapons. The metal is highly ductile, meaning that it can be easily worked and pulled into wire. For cultures which had minimal or crude metalworking abilities, copper would have been easy to shape and work with. Copper is also easy to alloy, and many of the early metal alloys featured copper. Current US pennies are all made of copper clad zinc, as I demonstrated by using my nibbler tool to remove part of the edge of a penny. Not pure copper.
