Comparing 16 PSI Radiator Cap to Carbonated Soda Can Pressures

I always imagined our coolant systems always being on the verge of blowing sky high when using the standard 16 PSI radiator cap. After researching soda can pressures, I guess 16 PSI is no big deal. It's just that boiling coolant/water likes to shoot out like a geyser

100 kilopascals is about 14.5 PSI. According to the article, even a cold soda has more pressure than that.
