Making Bombs with ZAS:
|
|
Make burny fire with lots of burning
|
|
Draw off 5000K gas from burny fire
|
|
Separate gas into oxygen and plasma components
|
|
Obtain plasma and oxygen tanks filled up about 50-75% with normal-temp gas
|
|
Fill rest with super hot gas from separated canisters, they should be about 125C now.
|
|
Attach to transfer valve and open. BOOM.
