When I was a youngster many years ago, I was impressed at a small aqarium filled with fluid where 50 or 60 moth balls rose to the top and then slowly descended to the bottom of the tank. They would then rise to the top of the fluid and descend again.
the visual appearance of rising and descending moth balls was incredible. I think it had something to do with the ? naptholene in the moth balls but I don’t know.
Would any of you know how this process worked and how I can duplicate it?
This is a guess. Moth balls continuously release their vapors, and, if underwater, the vapor forms bubbles on the fuzz. The bubbles cause the mothballs to rise. When they get to the surface, the bubbles of vapor pass into the air, and the moth balls are once again heavier than water. So, they sink, and the process starts again.
Someone will be along soon to tell me I’m right or fulla organic fertilizer. :smack:
Sounds kind of like a little physics display my 4th-grade science teacher liked to do. He’d take a glass of sprite or soda water and dump some rasins or a couple of plastic thumbtacks into the glass. After a few seconds, the carbonation from the beverage would collect on the object and cause it to float to the surface. There the bubbles would pop and the object would sink back down.
The fishtank thing sounds cooler, though!
