4 Ways To Make Yourself Invisible

I show you 4 different ways to become invisible

[jamierobertson]

Nothing beats my method when I was a child. Covering my eyes and saying ' Can't see me' worked every time.

I love the way James spontaneously reacts to the "cool factor" of his scientific demonstrations. Infectious enthusiasm makes his channel the success it is.

[westonding]

Magicians use a lot of these principles. “Black Art” is the term used to describe using a black object and using a black background to camouflage into the background. Great presentation with that illusion and the flock sheet clothing! I have heard of lenses being used in magic too. I have yet to see a more practical use or a larger variation of the Rochester lens cloak. I also have yet to see use of the same refractive indexing. Yet the possibilities abound!

In the first method, it is important that the background contains features in the same direction as the spreading of light. For example, the garage door had horizontal stripes.

The fifth method is to capture the background using a camera, and then displaying in on the front end of the object to match the background. Not simple or easy, but can be done. Only works for a narrow viewing angle, though. There have been some military experiments.

A sixth is to cover yourself with a cloak that can display all colors at a wide range of intensities with hundreds or thousands of "pixels", and then have some form of wide-angle camera that captures the colors, patterns and light intensity of the surroundings, and displaying some rough average of that on the cloak. Like a chameleon.

3:47 you can't change your own refractive index...
The invisible man: am I invisible to you?

[mtkoslowski]

First way: Just grow old like me. As the years progress I become more and more invisible to everyone around me such as in supermarkets. I am now noticed by no one.

[spudhead]

Main problem with being invisible is that you'd be blind. If light is passing through you or being bent around you, it's not getting to your eyes.

[altejoh]

Would love to see a follow up on this discussing cloaking meta materials. Works similar to the second method of invisibility shown here, but with a single material instead of four separate lenses

[uekiguy]

3:49 -- My 3-year-old son learned that he could never change his own refractive index and began to cry.

[OverlordMaggie]

I love the demonstration with the lenses and using the lines to demonstrate where the light beams focus to a point and where it is brought back to parallel.
Can I suggest colour coding the rays so that it is easier to visualize where the image is inverted and where it is brought back to normal orientation? Something like the top ray being red and the bottom being blue? This way where the image is inverted the red ray will be beneath the blue ray.

[ayakamoon]

I like the additional blank time at the end, to bypass the stupid end-of-video ads, for those of us who like to go back a few seconds at the end of replay parts without having to wait for the ad to finish to rewatch. Thank you for that!

[jayduffy]

What about if you used 2 invisibility shields. One in a vertical position and the other in the horizontal position but at a fixed distance behind the front one?

[corygrgic]

I love your videos. They are exciting and fun, but they also teach everybody things also. Keep up the good content!

[eastcoastartist]

At night, towns in war time England used to turn out all lights, so that plains flying above had difficulty seeing their target.

[sandrawong]

For the Rochester cloak, make the tiny focal point into a straight parallel beam using another lens, then you can be invisible for a larger area

[nizambabaniyazov]

And the next way to make it invisible is to gouge out your eyes 2:46

[atdynax]

I am curious to see what happens to the laser when you have a vertical screen behind the horizontal screen.

[spiderdude]

One other way to do it that I think the US military was looking into at one point would be to design a wearable suit that is made up of tiny screens and cameras. The cameras would record what is on the opposite side of the object, and the screen would display that video feed of what is behind the object. As you make the screens and cameras smaller and smaller, you would essentially have a huge network of screens showing what is behind the object from conceivably every angle. That would render the object essentially invisible.
