Also once you see that first nuetron in the deut it will start splitting the rest of the nuetrons and it will explode.
it worked for me, you have to hold down the spark for a while on the detanator so the nuetrons can escape the box. :D
2/10 would not bang. try compressing the deut (in console type: !set life deut 64000). also to make a destroyable detonator, use some deactivated pbcn in a glass box with the ctype neut
