Kay and Katyusha compare nukes

Kay

I shall call my science project 'Little Boy' - the ultimate tank-stopping technology!

Kay

The theoretical blast radius could disable an entire enemy formation in one go!

Katyusha

Hmph! You call that tiny model impressive? Katyusha is not intimidated!

Kay

Months of calculations went into this design! It's the perfect balance of power and mobility!

Kay

(I worked day and night on this... The theoretical yield is amazing!)

Katyusha

Behold! Katyusha's superior creation! Much bigger than yours!

Katyusha

Size matters in warfare, да? Pravda always goes bigger!

Kay

Wow, your engineering is actually quite sophisticated! The thrust-to-weight ratio must be incredible!

Katyusha

If you like that one, feast your eyes on Katyusha's ultimate creation - the Tsar Project!

Katyusha

Fifty times more powerful than your puny model! This would win any Sensha-dō match instantly!

Kay

So apparently 'theoretical weapons of mass destruction' violate the science fair guidelines...

Kay

Maybe we should have stuck with volcano models like everyone else?
