    How about a video on removing perchlorate from soil :). Maybe growing something in martian soil that has perchlorate and testing removal methods after. Growing fungus in soil composting then retesting. A method for cleaning the soil naturally such as using PRB's (Perchlorate-respiring bacteria). Just spit-balling here :)

    I just came across the fact, that gold is a near perfect reflector for infrared radiation.

    Can you suck out of a straw to drink water that it not quite at the boiling point due to being in a vacuum chamber? The idea being that there would be a lot less air pressure pushing the drink into your mouth. I would foresee the straw actually acting as a vacuum on its own despite being submerged in the water, but I'm not sure. And of course I haven't got the faintest clue how you would put the straw through the vacuum chamber.

    I've been liking your gardening series, and I've been getting into some gardening, myself. I currently only have about 50 square feet of garden, and while I have a few hundred more square feet to expand into, there are both hard and soft limits that I'll hit: soft from tree cover blocking sunlight, and hard from the size of the lawn that I can actually convert into garden. I would enjoy seeing a series where you do these kinds of things with as little space as possible. Kind of a "how to" get homegrown veggies in an apartment, conduct little science experiments in a suburban garage(safely!), etc. These things are clearly possible, and people who want to get that information certainly could, but it could help get people interested in this stuff if you could also say, "hey, you can do this one at home, even if you don't live on a ranch in Montana!"

    hey dude great videos cant stop watching them but i had a idear pop in my mind today when i watched your video standing in mercury (this is where my idear comes in) im from the uk and a few years back there was there was a brilliant tv science show called brainiac and they did this segment before and after the add break called will it sink or float they got a fruit or veg and in a comedy way they were like will it sink or float!! .... then the add break came on then when they came back they revealed the answer and then it slapped me in the face like a crazy old salmon codys lab could totaly do his own version of will it sink of float but in mercury and probbly not fruit as they all will probbly float haha! but if you feel this is a good idear you totaly have my permmision to use this idear just mention jack smith from the uk. really hope you like this idear and it becomes a reality, keep the videos comeing :)

  • Rihards Baks

    Hey Cody! I have made a robotic club in my university and recently I saw somebody testing a thermoelectric generator which you either heat up to generate electricity or connect it to battery and one of it's sides starts to heat up (to about 45 C) and the other gets colder (to about -15 C). I was wondering what would happen to these elements if stacked back to back glueing one's hot side to the other's cold side. Maybe they can be put in some sort of isolating tube to minimize the effect of it's surroundings on the temperature. The big question would be wether the last hot end would be really high like 200 C and the last cold end would be at -150 C due to the heat transfering from one to another. Maybe if this works we could find a cool use for it?

    Hey Cody, I'm sure the issues will pass. Not to worry. What better way to move forward than to concentrate on the science. So here's my contribution for now with a question: If I understand right in Earth's early history gigantism in animals and plants was in large part due to historical atmospheric composition (and maybe a different ambient pressure?). Could we take advantage of this and increase crop yields by artificially recreating this environment (possibly increased nitrogen concentration and/or pressure)?

    • animowany111

      Nope, in fact stirring soup cools it faster, because the hot soup that would stay on the bottom of the plate can mix, and evaporate more evenly.

    Hi Cody, I've recently watched a video on youtube about copper and it's medicinal properties that have been known in the ancient ages and foremost by the egyptians. They were showing that copper even breaks down MRSA in minutes. In what form could it be taken or ingested and in which dosis so that it would be preventive for any kind of infection in your body? Could it be copper sulfate, or are there plants containing enough copper which would be good for your health. Btw all this refers to if you want to avoid pennicillin and be kind of off the grid, like you mostly are.
    Would be nice to see a video from you about it. Or at least have a response
    Thank you and have a nice day

    Hello Cody. I am really thankful for your gardening series as it has led me to make a garden and plant crops. I was wondering if you could look into saving biennial plants for next year to collect the seeds. As a personal goal of mine, I think it would also be a good goal for you as well and it would be a great followup of this season's harvest. Regardless, I am glad to follow your channel and learn from you in the meantime!

    Cody I love your channel - what a sense of scientific adventure! I notice you improvise on equipment a lot, especially containers. With the low price of petroleum the demand for recycled plastic is limited and prices are near zero. I wonder if PET bottles, LDPE bags, and other recyclable materials can be crafted into vessels, piping, and other types of equipment to add another dimension of 'trash-to-treasure' to your projects?
    I've also heard you refer to energy costs numerous times during profitability estimates for refining operations. Would refined fuels from natural sources, like biodiesel for instance, help improve process economics?

    Lighting a fire inside a transparent tube of some sort, just a small fire so it doesn't burn through the oxygen too quickly, and then dropping it from a height and recording it in slow motion.
    I'm wondering if you will get the "zero G" flame shape you can see in some videos from the ISS. Seems like the kind of thing you might like doing and I'm sure you've used a slow motion camera before.
    I wonder what other zero G science you could do with a slow mo camera and a reasonable height?

    Cody, I just had a thought. would you be able to make an alloy between 3 parts beryllium 1 part aluminum and one part titanium? or, do you think that the different densities of the metals would cause them to remain separate. I ask because I'm working on my theory of making a more effect helicopter blade. I wanted it to retain the properties of titanium and aluminum while adding the lightness and extremely god thermoconductivity of beryllium. I'd do it my self but I don't have any of the resources to test it, nor the capital. Do you have any thoughts on the matter?

  • Howard Black

    I'm watching your video on recharging alkaline batteries -- thought I'd
    donate my virtual two cents for your viewing pleasure <g>. First
    penny: I remember when alkaline batteries first became available, in the
    mid-1960s. One of the selling points, promoted by the manufacturer
    (Mallory) was that they *could* be recharged! I had one set of C cells,
    which I used in my Norelco cassette recorder. It's been a while, but as I
    recall, they were the *only* set I ever used in that device! I
    recharged them over and over -- using nothing more than a small
    transformer and rectifier I rigged up, totally unregulated, with very
    little attention paid to recharge time. They *never* leaked, not one
    Fast forward a few decades, and the manufacturers changed the formulation to an "environmentally friendly" ("mercury-free") compound -- which would spew copious amounts of caustic goo at the drop of a hat when making an attempt to recharge them. (Seemed to me that there was a LOT more "oomph" in them when they "died" -- and that if there were some way to "agitate" the stuff while inside the battery, the life could be prolonged, if not actually multiplied, but that's just my speculation.)
    But fast forward a bit longer, and we find a few companies marketing "rechargeable alkalines" (as if the very *concept* was a novel idea!) -- and, a *very* few "alkaline chargers" (sold for use with *any* alkalines).
    While puttering around, I discovered a couple of odd facts: I could find NO difference in performance when charging the "rechargeable" alkalines OR "regular" alkalines, using either the "special" charger included with the putatively "rechargeable" cells, or, the "special" charger intended for use with *any* alkaline.
    More speculation: I suspect that the only difference between the "rechargeable" and "regular" alkaline cells is the *label* on the cell, with the secret sauce being contained in the *chargers*. I surmise that the trick is to carefully monitor the charge state, and carefully regulate the charge voltage and current, allowing the "modern" alkaline cells to be charged without leaking. We must love progress...
    If you're still reading this far <g>, can you tell me where to find one of your videos? I saw a snippet in something I watched earlier, which showed a small cube, levitating over four magnets. The cube had a tiny "dot" adhered to each of the four horizontal sides. The cube, apparently on its own, began rotating, and as I watched, it picked up speed.
    I'd like to see the whole video, and hear (or read) the details of its operation.

    Hey cody, have you ever heard of the quartz crystal dyeing technique of quench crackling? its basically heating a quartz crystal until its red hot and quenching it in strongly dyed water. There are some really incredible results you can get with this technique annd the challenge is getting it to dye and still hold together as there are thousands of micro fractures developing as the crystal rapidly cools. I thought this might be something of interest to you and i would LOVE to see your results. Cheers from Austria

      satellites have computers in them and they work in vacuums, but its not easy. without an atmosphere the heat generated by the electrical currents builds up with nowhere to go. so they need a way to radiate heat away from their components or they malfunction. this is all true but I'm sure there is more information available. I hope I've spiked your interest and answered a couple basic questions, you should look more into the subject with other sources. It would be cool if cody would do a demo though.
