/ 100
True
All mammals over 3 kg take about 21 seconds to pee due to the physics of urethra scaling.
Infact verdict: True (91/100).
The claims regarding urination time and urethra scaling in mammals are supported by multiple high-quality sources. Research from Georgia Tech, which won an Ig Nobel prize, confirms that mammals over 3 kg take approximately 21 seconds to urinate. This is due to the scaling of urethras in larger animals, which allows for consistent urination duration across different sizes. The evidence is robust, with multiple studies corroborating these findings.

True
Science
The physics of wider and longer urethras in larger animals scales perfectly.
The claim is supported by research showing that larger animals have longer urethras, which increases hydrostatic pressure and flow rate, allowing them to urinate in the same duration as smaller animals. This is corroborated by multiple studies from reputable sources.
