They don't swell up, there balls you put in your clothes so that moths don't eat your clothes. The moth balls do smell a lot though.
get them out of mothballs, polish them up a bit, and send them out into the world.
Well... Beside the fact mothballs are poisonous and doing this may damage your lungs, brain and nasal passages ???
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.
your nipples often swell up when you are cold, and often tickling them helps
Bleh. Mothballs are gross.
Because they absorb the water they're in - which makes them swell up.
As I opened the wardrobe, mothballs fell out.
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".
Putting the cell in a hypotonic solution makes it swell up.
I have never known mothballs to cause nose bleeds.
the mothballs will fly away
Your salivary glands (jaws) swell up and for men your testicles swell up and then shrink and they stay that way for the rest of your life!
