using objects from vanilla, rp2, and ic2, i was bored. 15 mins later i had a 3-layer thick reinforced stone box with rp2 wiring leading out to a switch on the top and a single nuke in the middle. flip the switch and run. BOOM. it broke 2 layers on 2 sides and 1 layer on the other 2. thats wasnt any fun :/. so i broke out more space inside and put wiring coating the entire inside with rp2 wiring and 9 nukes in the middle. i flipped the switch. for some reason that didnt work. this did not please me. i proceeded to replace some of the wiring with nukes and ended up with 30 nukes inside with the ceiling and floor coated with rp2 wiring as well as some wiring linking the floor and ceiling wiring. thats 9 nukes on the floor and 21 nukes in the middle. i turned on fly and flipped the switch and flew for the hills. before i post the picture i must mention i am doing this in a biosphere area(not biosphere mod just a biosphere region gened by a program called mcterra) and i placed this setup right beside my home biosphere.
here is the result of the 30 nukes:
don't try this at home kids lol. it barely missed my house simply taking out scaffolding on the corner but as you can see it still took out half my home biosphere. oh ya and it put me in a dead freeze for about a full minute.
update:
wanted more carnage so i started a fresh world and created a 16x16x16 block of reinforced stone and hollowed out a 4x4x4 area inside(that means it is 6 blocks on all sides between the now 32 nukes and the rest of the world. i set it up again with wiring spiraling to a switch and this was the result:
