How to levitate a magnet with no batteries, external power, or trickery. It floats on pure SCIENCE!
Below are some links you can use to purchase bismuth and the magnets seen in this video, but first a word of warning: Strong magnets can be really dangerous, especially if you have more than one. The 1" cylinder magnet that I use for this project could break bones if you let your hand get between it and another large magnet as they snap together. Smaller magnets that are pulled against a larger one might shatter on impact and fire out sharp chips. I recommend eye protection while working with them. Lastly, don't purchase strong magnets if you live around anyone with a pacemaker. Pacemakers are adjusted magnetically and could malfunction if exposed to strong magnetic fields.
Bismuth can be purchased here (this is an affiliate link): ebay.to/1TihOkv Note that to create large crystals like I do in this video you will probably need at least 5 pounds of Bismuth, but you could probably use as little as 1 pound to cast two small plates that would function fine for a levitator. They don't need to be nearly as thick as the plates on my prototype to function.
A 1" neodymium cylinder magnet can be purchased here (another affiliate link): ebay.to/1CXtGiD
And the 1/4" magnets (I incorrectly called them 1/8" in the video) (affiliate link): ebay.to/1RhIWTg
No, unfortunately this is not an over-unity device, though in a vacuum it would very nearly be a perpetual motion device as the magnet would have nothing to slow it from spinning without air resistance.
Here are some of my sources I stumbled on while researching this video:
The first video I saw on the subject: youtu.be/MMEkA2_N6vY
A great page for learning about the physics of diamagnetic levitation: kjmagnetics.com/blog.asp?p=diamagnetic-levitation
This video inspired the final design I decided to use for my build, very elegant: youtu.be/_Gtwg-jTItY
Finally, here is my own video I made a few months ago about how to make bismuth crystals: youtu.be/v8KYZHMkTHw
If you stuck around until the very end of the video you may have noticed I just launched a Patreon page! Take a look, and thank you if you decide to contribute! patreon.com/NightHawkProjects

Rope is one of the most valuable items to have in the wilderness, and this ancient method of creating it produces very good results. Even today some commercially made ropes are wound with the same process. Other natural fibers can be used to create rope (some being much stronger than grass), and this method will work equally as well with any other flexible material. Grass does tend to become brittle when dry which could weaken this rope, but even then it does maintain some strength. In moderate humidity weakness from drying should not become an issue at all.
Note that for best results, each of the two tails of the rope should be twisted an equal number of turns as theyre wound. That will ensure that the two coils wind around one another tightly and in a double helix pattern. If one side is twisted less than the other it will tend to stay straight, while the more twisted side coils around it like a spring. When I first started winding the rope in the video you can see I didnt do a very good job twisting both strands evenly for the first few inches, and one side was coiled more than the other. Try to avoid that, as it will be a weak point.
