Mothballs contain a substance called naphthalene or paradichlorobenzene, which slowly evaporates when exposed to air. This process is known as sublimation, where a solid transforms directly into a gas without passing through the liquid phase. As the mothballs evaporate, they gradually disappear, leaving behind no residue or physical remnants.
Mothballs typically contain either naphthalene or paradichlorobenzene as the active ingredient, along with small amounts of inert substances like clay or talc. These ingredients work by releasing vapors that repel and eventually kill moths and other insects.
Mothballs are typically used to repel and deter moths and other insects, rather than actively kill them. The chemicals in mothballs, such as naphthalene or paradichlorobenzene, release fumes that are toxic to insects and can interfere with their respiration and nervous system, leading them to avoid the area where the mothballs are placed.
Mothballs are usually made of naphthalene. Naphthalene has a boiling point of aroun 218oC (424oF).
Mothballs are nonpolar molecules. Alcohol can be polar or nonpolar depending on the specific type of alcohol.
This demonstration actually works better when the mothballs are added to a clear soda drink (e.g. 7-Up). The mothballs by themselves are just a little bit denser than the liquid, so they sink to the bottom. As carbon dioxide bubbles accumulate on the outside of the mothballs they eventually become buoyant and slowly rise to the top. While at the top the bubbles break and the mothballs sink again. This will repeat until the liquid runs out of carbon dioxide. As the mothballs are not soluble in water, if you use a clear soda drink you can still drink it when you are done (after removing the mothballs so you won't risk swallowing one and choking), but it of course will be somewhat "flat".

Mothballs are legally sold for use of the purposes listed on the label. It is illegal to use mothballs for other purposes including using mothballs in gardens.
Sublimation causes a change from solid straight to liquid or vica-verca, skipping the liquid phase altogether. Examples are mothballs and dry ice (frozen CO2).
Bleh. Mothballs are gross.

The scientific name for mothballs is naphthalene.
As I opened the wardrobe, mothballs fell out.
I have never known mothballs to cause nose bleeds.
the mothballs will fly away
While it is not proven that mothballs will keep wasps away, there is evidence that they do. Mothballs also seem to keep small rodents away too.
NO! Not safe!
