Reuse until it's empty to have unlimited space. You will hear an explosion but the limit par goes down two spaces. Lastly, place the nuclear bomb over the large air vent. Then, drag the contraption near the top of the screen, but not too high. First, glue the glue to the top of the cloud and add the large air vent on top of the cloud.
Spawn a cloud, glue, large air vent, and a nuclear bomb. Epic Fail is a reference to The synonym Epic Fail is classed as an Internet meme. The starite will spawn into Maxwell's hand.

After exploding, things in the area of the explosion gets the glowing and toxic adjectives. This animated screenshot shows the nuke, it will explode on Maxwell.

In Scribblenauts Unlimited, the nuclear bomb functions much differently from the previous games, as it does not kill everything and does not end the level. In this game, the detonation period is set to 8.11 seconds. In Super Scribblenauts and Scribblenauts Remix, it cannot explode when dropped, and will only explode when interacted with or destroyed. Nuclear bombs are extremely fragile, only able to withstand one bullet from a gun. When dropped, interacted with, or destroyed, it will create an explosion that eliminates everything in the level/map, including Maxwell and any invincible object(s).
