Since we've got a new show coming up that needs ideas, I can't help but think the show "Scorpion" MacGyver (the new one) is a fount of myths.
for starters:
Want to hide from facial recognition? pull the IR LEDs from a couple TV remotes, direct wire them so they are always on, and then hide them inside a pair of sunglasses. the LEDs will wash out the image on the camera, rendering you invisible to the software.

They did the same kind of thing to disguise number plates didnt they?.. that too was busted. If you want to be not recognised, get a Halloween mask.... |

If you want to be not recognised, get a Halloween mask.... it could be worse. at first glance, I thought remotes were UV instead of IR. now ask how that would work if the sunglasses were of decent quality... but yeah, here's a science trick you can do at home: put your phone on camera mode, and watch a TV remote through it. don't wash out much, does it? |

Ahh.. actually, mine does.... Mine is "IR-Sensitive", as in it takes part of the IR spectrum into account when doing low-light photography?.. it deepens the shadows and dark parts?.. Not that I use it, because not three foot away on the end of the couch is my Canon DSLR. This all depends on what type of camera you have, and if its a DSLR or not. Most DSLR these days have IR, and its getting more and more into the Phones as well. My Phone camera does the IR thing, because it can, if needs must, be turned into a TV remote. Noees do not must at this house?. I dont know how because I do NOT have the App for that.... I dont needs it?.. my Pad can do all of that and more, and my Laptop has the app for that, using wifi I think..but, more importantly, on my Laptop, I can see the bloody writing on the buttons... Which is actually better than the real remote for the TV. |

I get you now, and yes, you are right, but didnt they also test IR on the numberplate thing and found you cant get a hot enough light at that distance to wash out even a crappy camera?... |

I run into it doing nighttime pictures of fire practices, because of the reflective on the gear. |

But I believe you can do an Un-Tag thing, and ask them to remove the pic if it wasnt done with your permission... I dunno how. I have never got that far, I dont fake-book.... |

in a commercial trash compactor, you can compromise the hydraulic ram by bracing a swiss army knife (screwdriver blade) in a pipe and wedging it between the ram and the back of the chamber. (it will punch the rivet through the ram and cause a fluid leak.) take extension cords, cut them in two (with your swiss army knife) strip them out, and use them for an electric whip. - a strike knocks the victim out. two cardboard discs threaded on a pair of shoestrings can be spun at 20,000 RPM. (reality bit: you do this with a button and heavy sewing thread thread through opposite holes in the button, and tie it in a loop. wind it up and then spin it by tensioning and relaxing the loop.  it might actually be possible to get respectable numbers from the button. |

I have seen this done with a CD.
Make two holes with a drill just outside the centre hole opposing sides, pass through some string, fishing line, whatever, and make the loops, then spin as above picture shows.
If you also drill some more holes at a slight angle just inside the outer edge of the CD, it whistles as it spins...

That made me laugh, as that was where I started doing Beta testing, being I was one of the beta testers that fought off the worst of the bugs from about AOL 4 onwards?... However, I do have a large stack of bunt "coasters" from burning processes where I was doing backups before I could afford re-writeable disks... well, when I say afford, I was getting a good supply from work at the time at something silly like 10p a disk cost price, re-writeables at that time were about £1 a disk, grab a stack from work at three quid for a good three doz. stack, or pay the bigger price?. That and CD's used to drop out of the weekend newspaper magazines with all kinds of silly offers on them but some bloody awful free music. |

With enough disks you could build a throne and be king.  But there will always be someone who want's to dethrone you.  |

new season, new myths. this one might actually be worth a go.
three people, all assumed to be in above average physical condition. a pole or pipe about 20 feet long, and a vertical wall.
two people at one end, one at the other, and the two provide pressure to allow the third to "walk" up the wall. I think I've seen it elsewhere, as well.

I think I've seen it elsewhere, as well. the other options included: using a tire iron on a cable or chain (I forget which) to catch a car by the bumper, and then wrapping the cable or chain around the axle on a (moving) motorcycle sidecar to make a winch concealing a (partially disassembled) smartphone in a soccer ball to make a spy camera I missed the exact components that went into his improvised submersible propulsion device, but he made that, and then used an oxygen bottle as the source for a SCUBA rig. |

new season, becoming even more silly:
bad guy in a dodge ram, good guys in an MRAP
1: the MRAP windshield won't stop a 9mm pistol round (corollary, the panels of the windshield can be kicked out from the inside)
2: the MRAP can't PIT the ram
3: by hooking the winch cable from the MRAP onto the pickup, and braking in the MRAP, the (freewheeling) winch cable attachment is strong enough to stop the Ram, without the copper eyelet that keeps the cable from unspooling itself, blowing out
