Growing beans with an enchanted water bottle
Timespan: Winter 2023

I am a big fan of pseudoscience.
One reason is I believe most novel scientific concepts were first dismissed as being ridiculous "psuedoscience". Imagine being the guy who first thought little invisible bacteria were making us sick while everyone else was busy believing in the four humours — laughable!
Anyway, in 2021 I bought a water bottle which claimed to be enchanted — the bottle is made of "Programmed Silicon" so any water stored in it will be restored to a more natural state which is good-for-you.
I was intrigued by the idea, but the thing that really got me was a sentence on the website — the company was founded by a former strawberry farmer who said strawberries watered with the enchanted water were "18.1% more plentiful".
I am a sucker for the quantitative
That is testable! Woo/hippie products usually stick with qualitative effects like "feeling better" or "being healthier", and only show numbers when reporting on surveys e.g. "80% of people said they slept better". They stay out of normal science because usually they can't show results. But here was a company claiming a hypothesis and experiment — I was sold, and immediately bought the bottle.
The bottle
When the bottle came, I really enjoyed it. The cap comes off quickly with just a tug, and the cap + sleeve placement makes it difficult to smash into pieces. The fact that it's all glass and cork means there's no possibility of chemicals leaching into the water. The cork was even fully-cork, not the particle+glue stuff that gets shilled as cork. The bottle also makes a pop when uncapped, the tone of which changes with water level. How cute! I even made some Tiktoks with it. The only downside is the weight — when full, the bottle weighs 1.5 kg and holds only 750 mL of water.
Anyway, I don't want to be accused of promoting questionable hippie water bottles so I won't tell you the brand, but it was actually good. And because it was so good, I forgot all about testing it until 3 years later, in the winter of 2023.
In college, I did a plant experiment where I had to grow three batches of arugula. This takes usually takes 3-6 months, but it only took me 1 to kill them off. With respect to my skill level, this time around I decided to try growing bean sprouts.
Mung bean sprouts
My Asian readers probably have some domestic experience with this, but for my worldly audience, here's the dig: if you keep green/mung beans wet for 3 days, they become these big watery sprouts which you can cook and eat. Some people like the flavor, I personally like how fast they grow.
Excuse the German
I bought some mung beans in the store and soaked the whole bag in regular tap water for a day.
Beans swelled so much they split the bag they came in!
I took two yogurt containers and put a paper towel at the bottom, then I measured out 50 g of the beans into each bin. One got marked near the rim to denote it as the experimental group, and the other didn't.
Marked vs. unmarked bin of beans
Every day I filled the marked bin with enchanted water that had been sitting in the bottle for at least 5 minutes (manufacturer's instructions) and then drained it, doing the same with the unmarked bin except with fresh tap water. Then both bins went back above the fridge. Because the mung beans get bitter in the light, I wrapped both bins with foil and also inserted a cover of foil after each moistening.
Magic water for the marked beans, tap water for the unmarked beans, foil to keep them in the dark about it
After four days, I took out both bean sprout bundles. There was a clear difference between the two visually. The magic beans are clearly greener, and a bit longer too.
The two bean conditions, left is tap water and right is magic water
The tap water beans weighted 217 g, while the magic beans weighed 224 g. Adjusting by the initial weight of 50 g, this represents a growth factor of 3.34x and 3.48x respectively, too close to declare any difference by condition.
Nearly the same weight. Foil is tare'd out, and the paper towels are sequential ones from the same roll.
Since the sprouts were food, I had to eat them. The tap water beans definitely tasted sweeter, or at least less bitter than the magic water beans. While they shouldn't've been exposed to more light, the bitterness might come from the fact that the magic beans did get more light after they grew tall enough to escape their paper towels. Or maybe the magic water makes them bitter. Who knows?
Mmmm... sprouts
Some things were not controlled, and in hindsight, should've been. In order of perceived importance:
water was added each day until saturation, and the drained water was not controlled/measured
containers were not pitch-black, and light kinda depended on sprout height
magic water was left out for 5 minutes after coming out the tap, while the tap water went straight in the bin
sprouts were grown as a group, so I can't do statistics across members of each population
bean groups were equalized by weight, not by count
Sharpie marking might have influenced growth rate of the experimental condition
I know, I know. And I will probably run this experiment again more rigorously in the future and solve all the above limitations. If you think I'm missing any conditions, please reach out on Twitter or email to let me know.
So we didn't prove our initial hypothesis about plentifulness, but there was clearly a visual difference. I think this is enough evidence to investigate further!
