I thought these very long pole nets, invented by these kids in China, are an ingenious solution to a problem of many kids in the developing world: need some money. Their particular problem was that scores of tourists float by in boats going down a scenic river, but they don't get quite close enough to beg money from. Some tourists would be willing to donate if they could get some money to the boys. The solution is to lash a fishing net to a long bamboo pole which can reach the boats are certain turns. The boys reach their poles out and the tourist deposit the bills. The one in the picture is dropping a red 100 renbi note which is worth about US$8. That's a big tip for these guys. But the solution is so clever I'd almost be willing to give them something for their effort. The photographer and source for this picture is unknown; I found it at this site of China photos.
I am not at all sure why Ted Kaczynski made this gun, unless it was to avoid the detection of having to buy one. It's remarkable in its craftsmanship. Don't know if it worked, but given how meticulous he was, it probably did. This photo is part of the government evidence against him, found at this CBS site, without much explanation. If you know more, write.
In the comments, Cory H. supplied the answer to why the Unabomber made this gun, and whether it works:
Reprinted from his diary in the Government's Sentencing Memorandum, which explains that agents discovered a completely homemade, operable handgun, as well as a corresponding written description of its creation and purpose:
[A] few days ago I finished making a twenty two caliber pistol. This took me a long time, for a year and a half, thereby preventing me from working on some other projects I would have liked to carry out. Gun works well and I get as much accuracy out of it as I'd expect for an inexperienced pistol shot like me. It is equipped with improvised silencer which does not work as well as I hoped. At a guess it cuts noise down to maybe one third. It is said that it is easy for machinist to make a gun, but of course I did not have machine tools, but only a few files, hacksaw blades, small vice, a rickety hand drill, etc. I took the barrel from an old pneumatic pistol. I made the other parts out of several metal pieces. Most of them come from the old abandoned cars near here. I needed to make the parts with enough precision but I made them well and I'm very satisfied. I want to use the gun as a homicide weapon.

I tried to track down the provence of this image, but was unsuccessful. It shows some kids using a grocery shopping cart as a make-shift basketball hoop. Very clever!
