Am I the only person that's ever wondered this?

I found a very cute metal tin at the op shop with 'decorative cams' printed on the lid. The tin is about the size of three slices of bread stacked one upon the other. Inside it I found about twenty circular plastic things (the 'decorative cams'?) resting in metal slots which look like they would attach to something - perhaps a sewing machine?

What are they, and how are they used?

I've become some what addicted to Alchemy. I know that it was an early form of Chemistry and every other type of Science, but i want to know if you think it can be done by drawing a Transmutation Circle, putting the ingredients in the middle, clapping your hands and letting it turn into something new. If you think im either mentally retarded or just plain crazy then i will one day prove you wrong and show you that it might some how be real.

I read about this online and have tried it twice. Both times it worked beautifully, and the salted candles burned a couple hours longer than the unsalted candles. I've used the method on cheap dollar store candles. What does the salt do to the candles to change the way they burn?

Every four years we add a day to february to balence the difference for how long a day should actually be.
I've also heard that every 100 years we take another day off to balence. Is this true?
And if it is, how would we calculate the true length of a day?
