My name is Devin Fensterheim.  I am a sixth grader at Edgar School, 

Metuchen, New Jersey.  I saw your page on the Internet saying that if 

someone has any questions, to contact you.  I am working on an invention

for my science fair project.



I am inventing a candle alarm.  When the candle gets below a certain 

point, the alarm will go off, preventing fires caused by candles.  For 

this alarm, I am going to include a small box at the base of the candle.  

When the candle gets below this point, the temperature at the base will 

rise, causing the alarm to sound and a red light to flash.  



Inside the box will be a thermometer that converts the candle heat into 

electricity.  When enough electricity from the heat is generated, the 

alarm will go off.



I do not know how to build my thermometer which will convert the heat to 

electricity.  I already did a lot of research, but I still can't figure 

out how to work it.  Do you have any idea on where I can look for more 

information? 



Thankyou,





Devin F.
