thank you @TheBlueTronOfficer
pretty cool blimp, was here before hygrogen
@plutoniumfusion imagine helium
Fun fact: CO2 blimps are slightly too heavy to float, because CO2 molecule (weight:34) is heavier than O2 (Common oxygen in the air. Weight:30)and N2 (Common nitrogen in the air. Not a russian rocket. Weight:28), molecules that make up most of atmosphere. So this blimp can only float in giant ozone tank or planet with chlorine atmosphere. Since chlorine is very toxic, find a planet with argon, a safe gas, to float a CO2 blimp.
