hi!

im taking media studies, i would like to make a small cardboard house/street that i can blow up.... (not to bothered how realistic the final thing is but it sounds fun!)

what i need to find out is what is a good explosive to use.... im looking for something that will blast out of the windows in flames, not blow the box to dust,  and not injure anyone...

my old chemistry teacher suggested a rig using custard powder that is ment to work quite well. my other option is using a can of lynx and a lighter?

any help would be great... ill post my final video obviously!
