Yyyeaahh...maybe I should clarify a little. They're tripods(formally referred to as Fighting Machines) that have metal tentacles and are ninety feet high. The aliens are Martians, which are bug eyed lumps of flesh with sixteen long, whip-like tentacles. The "lazor beams" are actually Heat-Rays, which shoot out invisible beams of heat. Except at night, under the right lighting conditions, where it looks like a faint green beam of light. The tripods can shoot projectiles out of a cylindrical magnetic accelerator. The projectiles do not explode upon impact, instead releasing a gigantic cloud of poisonous black vapor. There is also a large steel cage carried by the tripods, which they put humans in. The Martians feed on protein in its simplest form - blood. For some reason they prefer human blood. We don't really know why, maybe they're picky or something. There's also this Handling-Machine, which looks like a five-legged robotic crab thing. It has a lot of tentacles, some with various tools on the end, and it also has a steel cage on it's back. The aforementioned "foghorns" are actually the sound of the Martians communicating from inside the tripods. It sounds something like this. *ahem* AAAAALLLLLOOOOOOOOOOOOOOOOO!!! If you've seen the 2005 film by Steven Spielberg, you know what it's like. The Martians have also brought along this fast-growing red weed, which contrary to what is shown in the 2005 Spielberg film, does not get fertilized by human blood. It feeds on water. Oh yeah, and the Martians are only invading the UK. And it's 1901 or so. And they traveled to Earth in big pods shot out of a cannon on Mars.
Is that clear enough for you?
