This isn't a biology experiment gone awry, it's a life hack. Specifically, this one-from Raychelle Cassada-Brady, who's been featured on the Discovery Channel's Dirty Jobs and National Geographic's Explorer. She explains:

For the past six years I have been teaching high school Advanced Placement Biology classes in which my students and I have been trying to discover a correlation between the amount of water we drink and the color of our urine. After more than 60 trials, we have finally concluded that drinking copious amounts of water will result in colorless urine and a superior aptitude in the field of biology. Why: Urine color can indicate your overall health, ranging from yellow (slightly stressed) to dark brown (slightly jaundiced). So far, we've found that our urine turns clear when we are well hydrated. In all cases, the darker our urine, the lower our scores. We've also discovered that when we drink copious amounts of water before taking the test, we ace it every time! How: We drink several large bottles of water each morning before our test. Sometimes we even drink up to two bottles an hour for several hours before our test just to be sure we're well hydrated and to get rid of our yellow pee. Benefit: We've had 100% success since discovering this technique. It's not a huge scientific achievement, but it helps us learn about our bodies when we're young and thus have more control over our health as adults. It also gives us confidence in knowing that when we test ourselves later in life, we'll have a good idea of what to expect based on our hydration level at the time of testing.

"Drink plenty of water so your pee is clear." - Raychelle Cassada-Brady, science teacher and Insta-Genius

You don't want to go overboard—drinking too much can be dangerous—but a little extra water is a healthy habit that could help you remember more biology facts later in life (or at least help you ace your next test).
