YOU WILL NEED:

breakable metal

spark or something that shocks stuff

and gunpowder and things that explode

ok. make a circle of breakable metal then create a hole in it. then use more to create some kind of electric fuse.

NOTE

make sure the circle of metal is thin but not to thin

when you make the circular contaner

fill the metal hole with gun powder and umm... EXPLODY THINGS!

your final result may look something like the thumbnail.

when you're ready, spark the fuse of metal, and when the electricity enters the circle and...
BOOOOOOM

the reason why i told you to make the round container made of metal. was so it could break and actually work and explode correctly. because the pressure inside will blow the round thing apart.

thanks for reading! have a good day!
