Cody Reeder is an American educator, amateur scientist, mechanic and YouTube personality. He runs the popular YouTube channel Cody'sLab.[2][3][4]

Key Information

Life

[edit]

Reeder was born and raised near Grantsville, Utah,[5] on "an off grid ranch in the west desert".[6][7]

He has worked as a mechanic,[6] and studied geology at Westminster College and Utah State University,[5] but was later academically suspended due to a low GPA.[8][9]

Experiments

[edit]

Having joined YouTube in 2011, Reeder initially began posting videos of his experiments to show to his grandmother: "I would do science experiments all the time anyway ... Then other people started watching them", he explained in a 2017 interview.[10]

His channel Cody'sLab reached 100,000 subscribers in October 2015. Having not received his silver play button six months later, Reeder celebrated reaching 250,000 subscribers by forging a homemade play button out of genuine silver.[11] He reached 1,000,000 subscribers in early 2017.[12]

Reeder first gained considerable media attention in 2016, after posting a video of himself drinking water containing a small, diluted amount of cyanide. The purpose was to prove how the dosage defines toxicity.[13] While emphasizing that the amount he consumed (17 mg) was considerably smaller than any lethal dose, Reeder said he did experience certain symptoms of the toxin such as rapid breathing. This video, among others, has since been removed from his channel. Similar experiments however, such as him drinking heavy water, "hydric acid" (tongue-in-cheek), and breathing in all the noble gases, remain available as of January 2021.

In 2017, his channel was suspended for two weeks, following received strikes. The reason was suspected to be a video on the science behind how small insects (Reeder used fruit flies, of unspecified species) can survive being microwaved, while larger ones cannot.[3] Preceding the suspension, an increase in flagged videos and concern that his account may be deactivated, prompted Reeder to create a back-up channel.[14] An article on TubeFilter blamed "overzealous viewers" for generating the automatic strikes, writing that Reeder's channel is both "wholesome and family-friendly", and commenting on how YouTube's strike system also affects those "who stay well within the bounds of acceptable content".[4]

In a 2019 video explaining a period of channel inactivity, Reeder mentioned how some of his videos, although intended to be used for educational purposes, had been flagged by YouTube, showing a warning he received for a video on making gunpowder from urine. In the same video, Reeder explained how he also had been visited by United States government agents, after publishing several videos on isotope isolation and nuclear radiation. The agents, equipped with geiger counters, did not find anything of concern, and Reeder himself said that they were only trying to help him not get in trouble in the future.[15]

He has also received media attention after becoming one of the 100 finalists of the defunct Mars One Mars colonization program, having been selected from over 200,000 applicants.[5][7]

These videos emphasize protocols, such as proper dilution, protective , and immediate medical monitoring, to educate viewers on the boundaries between and . By showcasing real-time reactions and physiological effects, Reeder aims to demystify complex concepts like and reactivity, always stressing that his approaches are not recommendations for replication. One notable demonstration from 2016 involved ingesting a diluted dose of 17 mg of dissolved in water to illustrate toxicity thresholds and the body's response to sub-lethal exposure. Reeder reported experiencing rapid breathing and mild symptoms shortly after consumption, attributing these to cyanide's interference with , while emphasizing that the amount was far below lethal levels—typically around 1.5 mg/kg body weight—to avoid severe . This experiment drew widespread attention for its educational intent but also highlighted risks, as even small quantities can cause acute effects if mishandled. Reeder has explored isotopes through a series on producing (deuterium oxide, D₂O), where he electrolyzed regular water to concentrate , achieving up to 1% purity in one setup. He tasted the resulting to note its slightly sweeter flavor compared to ordinary water, explaining how the heavier isotope alters molecular bonds without posing significant health risks in small amounts, though prolonged exposure could affect biological processes. This work underscores techniques and their applications in nuclear research, with Reeder detailing the energy-intensive process and safety measures like ventilation to prevent gas buildup. In demonstrations involving , Reeder inhaled samples of , , , , and to observe voice modulation effects due to differences altering vocal tract . , being lighter than air, raised his pitch dramatically, while denser gases like lowered it, providing a tangible illustration of gas properties and sound wave propagation; he cautioned against prolonged due to asphyxiation risks from oxygen displacement. These experiments extend to broader handling, where Reeder discussed stable versus radioactive variants, always prioritizing safety through limited exposure. Handling mercury featured prominently in Reeder's physics explorations, including an attempt to flush 240 pounds (about 109 kg) of the through a to test its flow dynamics compared to . Due to mercury's high (13.6 g/cm³), small volumes flushed easily, but larger amounts formed a viscous plug over the drain, requiring manual intervention; Reeder explained the principles of and while wearing protective gear to avoid vapor inhalation, a key risk. In another setup, he poured 640 pounds (290 kg) into a reinforced tub and successfully stood on the surface, demonstrating where his body was less than mercury's, allowing flotation for objects less dense than mercury, like an ; this highlighted and the metal's toxicity, with cleanup involving specialized containment. Reactive metals experiments included reacting cesium with water to celebrate reaching one million YouTube subscribers, molding the highly reactive into a play button shape for visual impact. Cesium's vigorous —producing hydrogen gas and heat up to 100°C—illustrated periodic table trends in reactivity, with Reeder conducting it in a controlled environment to mitigate explosion risks from the metal's low ignition temperature. Safety was paramount, as he used minimal quantities and fire suppression nearby. Reeder demonstrated by embedding magnets into his , creating a "magnetic finger" to interact with metallic objects and visualize field lines. This allowed hands-on exploration of magnetic force gradients, such as attracting or repelling other magnets, while he explained Lorentz forces and the need for surgical precision to avoid nerve damage; two years later, he updated viewers on the implants' stability, noting minor discomfort but no major health issues. In biology-physics crossovers, Reeder microwaved of varying sizes to show effects, where smaller specimens survived brief exposure due to lower absorbed energy, while larger ones perished from rapid temperature rise. He linked this to electromagnetic wave penetration and in tissues, advising against home replication due to leakage risks in unmodified appliances. Broader chemistry series covered gunpowder synthesis, extracting components like from via and , then mixing with and to produce black powder. Reeder tested rates, achieving controlled burns that propelled small projectiles, to explain pyrotechnic chemistry and oxidation-reduction reactions; he stressed legal and safety constraints, including spark-free handling to prevent unintended detonations. Hydrogen generation experiments involved reacting metals like sodium with in a hybrid setup, producing H₂ gas for and demonstrating —yielding twice the volume of from sodium's —while venting to avoid buildup. These efforts collectively promote through risky yet informative demos, always with caveats on professional oversight.
