I think I can speak for everyone, that if you need anything, just let us know!! Hope you are well!!

    what happens if you melt a magnet ??????????

    • Teddy Robertson
      Teddy Robertson 9 days ago

      The magnetic properties destabilize and it loses most if not all it's magnetic properties, though I believe it may still carry some. Metals are magnetic because of their electrons all point in the same direction, thus giving them a stronger and more noticeable force. If you heat it up, the electrons will excite and move out of position, thus reducing it's magnetic effect, but I'm sure it will go back to being magnetic, but probably not as powerful.

    Any idea how to make ~27GHz transmitter? I want to make HHO. ~ 27GHz is resonant frequency of H₂O. I'd like to make HHO in my backyard, lol. If we could do this it would open up the possibility, for fuel cell use, for combustion motor use, etc. I think hitting water at it's resonant frequency facilitates first part of the best pollution free energy process. Please help me figure this out.

    Would it be possible to create an energy bolt by firing a spray of conductive pellets, with a small spread, and having a microwave emitter electrify them to the point that electricity jumps between them? And no, it wouldn't be conductive pellets, I haven't had much time to solve that problem, but it is possible to make an energy bolt with today's technology right???

      I suggest to have a steady flow of heat into the crucible, and a few inches above it, have a few small holes for gas escape. This should allow for some good speed. Also, definitely cover it, and leave no holes in the lid

    H2s is a deadly gas, I provide H2s Safety training and support for working around h2s. If you'd like to do more projects with the gas, I would highly recommend you contact me. The amount that you had was very dangerous to be around even at a low amount. H2s burns and is even explosive between 4.3% (43,000ppm) and 46%(460,000ppm)

    I have h2s detection equipment and personal protection equipment I would be willing to let you use.

    Hello there BYS! Because you said it was almost impossible in one of your previous videos, I wanted to know if it is possible to stop a thermite reaction. I have a couple of ideas how to but I don't really have the equipment or resources to try, so I wanted to ask you if you could do a video to try and stop a thermite reaction. I thought of using liquid nitrogen but it might not be cold enough. So if that doesn't work, then you could try to drown it out of oxygen, or use liquid helium. In theory the liquid helium could deprive the thermite of oxygen, and cool it down at the same time. I think it would look good in slow-motion, but might be very dangerous. Thanks for reading this, and don't burn yourself!

    Ideas for future videos:
    1 Microwave Mercury, Gallium, Indium, sodium, potassium, or other metals that can melt at low temp.
    2 Things you wouldn't expect to burn: Strip of aluminum foil coated in a thin film of wax, grinding iron shavings, ferrocerium rod
    3 Fire a Hi-Liter and other household items from a paintball gun and compare the difference in ft/lbs or oz/in of energy
    4 Calculate the caloric content of different foods by burning them to raise the temp of a specific amount of water
    5 Calc exactly how much the coriolis effect affects bullet trajectory @ 1000yds (guessing it's around 1mil from experience)
    6 Household hacks such as deoxidizing copper in 5mins with Taco Bell hot sauce, clean chrome bumper with Coke, etc
    7 Testing non-poisonous pesticides such as lavander oil or eucalyptus oil on bed bugs, vinegar+Dawn+water spray on flys, cayenne pepper or diatomaceous earth on ants and other insects
    8 Test how different inert gasses or other gasses affect the pitch of your voice due to different density vs air.
    9. Various uses of potassium nitrate (gardening, smoke bombs, solid rocket fuel, etc) For colored smoke bomb, mix potassium nitrate with just enough Karo syrup to form a thick paste, cut top off aluminum can, fill 1/3 with mixture, cut up about 5 pre-1982 pennies into 4 pieces each, push them into the mixture, top with 1tsp black powder, cut 4 vertical slits in can just down to level of mixture, fold the 4 can flaps over each other like you're closing a box, use an awl to poke a hole in the center through all 4 flaps, insert cannon fuse, light, and watch cool green bursts of color as the copper chunks burn! Use different metals/chemicals for different colors such as iron shavings for red flame, sulfur for yellow smoke.

    Do you work with the Science Channel? Because I see some of your stuff on there sometimes. Like on a commercial for it I saw you blow up you fish tank with the molten salt?

      LOL I just looked it up, Gavin's funny. Those were just .22 bullets though, and they weren't fired from a gun. They wouldn't even have enough energy to make it into the neighbors yard. Also, all my neighbors know what im doing, and watch my YouTube channel. The one directly behind me hangs over the fence and watches me film, even lent me a crossbow for a video! I like my neighbors, and id like to continue doing experiments in my backyard so as a courtesy I let them know if im doing anything loud. I would especially never want them to get hurt, so I take all the actual dangerous things the back 40 of my friends property in farmland.

      I did get a nice boost in views from the mention though! Maybe I should start some internet drama ;)

    I suggest a new Liquid Nitrogen video, one where you use enough that you can freeze like 50-80 percent of your backyard pool solid in a matter of seconds, I saw the video where you put out the burning pool alcohol fire with a small amount of liquid nitrogen, a bit more and you could make a pool sicle ha ha ha

    Hey TheBackyardScientist, I recently watched a video where they melted metal using a magnet. Seeing as melting metal is a deep rooted passion, how does it work and what other kinds of metals can you melt using this method. Learning from one of your videos, the suspended molten metal does lose it's magnetic properties once it reaches a certain temperature, which was interesting enough to me that metal can get that hot just from being suspended by a magnet. It looks like a powerful electro-magnet, not sure, not my area of expertise. Here's the link

    for the experiments where you pour things in water like molten salt, sodium, etc... you should figure out how to contain them in a capsule to drop in the water so that the reacting agent will be completely submerged upon release.

    I've seen a lot of videos with molten aluminum being poured into fire ant hills to make great art.

    Do you think the same could be accomplished with molten glass? I'd love to see a sculpture made with say green or blue glass if it were possible.

    • Mr. Mediocre Gamer
      Mr. Mediocre Gamer Year ago

      Yeah, and it came to me that the actual dirt around the glass would probably stick to it so it wouldn't wash away very well... so the final effect wouldn't be how I pictured it anyway. :(

    • alexsoutherland
      alexsoutherland Year ago

      Not the Scientist, but I think the molten glass could indeed be used to substitute the aluminum, but would be harder to dig out of the ground (due to the brittleness of glass)
