I need to find 2 chemicals that are safe for school use and that react safely that would be able to reach 100-200c thanks

well it is that at the moment but it could be bigger. 11.43cm is 4.5" and i plan to use that one

well the parabolic mirror i think should be 11.43cm diameter. The attachment has all the info on that you should need except the 15 degrees c should be 11 as that is the yearly average temp

how can i calculate the surface aria of a parabolic mirror

so if the souse of light is the sun it can't be any hotter than that

Is there a sum to work out how hot the point of focusing could get with a parabolic mirror? thanks, matt

yer i sore that lol and i was going to get it off u tube as well

anyone elce got any thing to say?

lol thanks

thanks mate i will do some experimenting with mirrors and other type of lenses and all that. and i think thew water butt will be slightly lower than it is in the picture.

new diagram.bmp The question im going to arks is what type of lenses should i use and what dimensions would it have to be to work efficiently. Also any other improvements i could make would be yourself

k and it would be fully in closed

if i change the liquid would it work more efficiently. and would a normal magnifying glass work to boil water. im going to do my own exsperments as well

how would i be able to make it more efficient but without doing much changing.
