Did candle "alarm clocks" really exist?

by Indigo_Flair

I saw a picture recently of a candle with nails in it, along with an explanation that people used to place nails in candles so that when the candle melted, the nails would fall and make a noise, thus waking up the sleeper. Is this true? If so, when was this practiced and by whom?

Thank you all for your hard work!

This is a good question, although it would seem to work to some degree with a nail falling , it is doubtful that it would wake anyone up in deep sleep unless it hit something metal, even then the noise would be brief and probably just bake in part of a dream state.I doubt that anyone did this and it is likely a myth like hundreds of others but I have no proof either way.
