|Backdraft Bubblish Gum|
|Manga||The Battle Begins|
|Anime||The Battle Begins (episode)|
UsageTōru inserts some bubblegum in his mouth and chews it, blowing up a balloon with a vacuum inside it that contains flammable gas. The balloon is lighter than air and, as such, is able to float. When given a command, the balloon pops, causing the flammable gas to react with oxygen, which leads to an explosion.
