So, I was wondering, the classical explosion that we all see in movies and so on, the big fireball and the smoke, how do they make it? C4? Gas release?

i yhink they use allot of gasoline nad some explosives

Well i knew they use gasoline but, how do they pack it and whats the detonator?

I believe its called a Cremora Firball, and which they add sound.

but how exactly do you make this?

searc for it it s a thread about it

A ghost mine will work also, with a chemical colorent ( also on skylighter)

its an iron pipe, half filled with denatured alcohol(eythl alcohol works best, the denaturing chemical in denatured alcohol gives the fireball an orange flame), add a chemical colorent IE: anything with strontium for red, anything copper for blue/green, and so-on.(or gasoline would just make a nice fireball), take a quart ziplock baggy, place some lift charge BP in it, place and electric igniter(e-match ,ect...) in the bag, tape it tightly closed, and then tape it again to make sure the alcohol/gasoline wont seep through that tape. get atleast 200ft away, and set it off, the result will be a large fireball as seen in action films. look in skylighters newsletter archive for "ghost mine" to fint he full directions, amounts, ect.

if you want the desired effect, put some det cord on "starter fluid" (which contains a lot of ether)

it makes a sick fireball

the thing i hate about explosions in movies is that A) there is never going to be that much fire accompanied with that much noise...loud noise not much fire, lot of fire not much noise and B) the sound travels somehow magically the same speed as light in movies. they need some physics classes

basically what you want is a thermobaric bomb

What I would like to do is replicate a really huge a-bomb mushroom cloud... Anyone know how to do this?
