Question

whats the stuff the magicians and ninjas use where they throw it at the ground and the smoke comes from the ground??

Answer 1

sorry i don't have an answer. but what is this chick talkin about? did she just decide to make up her own question?

Answer 2

Your best bet is to search for magic supplies and tricks online, or go to a decent magic shop.

f**t bomb**

very deadly

magic smoke

Answer 6

Okay, let's talk smoke systems. I know, most of you are thinking "hey, I haven't got a giant scale plane with a gas engine, so I can't make smoke." NOT!" I don't fly anything bigger than a .90 four-stroke, all my engines run on glow, and many of my planes have smoke systems onboard. I just love to burn up a clear blue sky with some smoke, and we're not talking about a p**s-ant dribble that can be mistaken for a rich engine run. No sir! I'm talking nice, thick, white smoke - thick enough to lay a haze across the runway on a low pass. I've rigged many of my planes with smoke and I've learned a lot from it. I'll be happy to share some of my hard earned insights with you (feel free to ignore them if you're feeling smug and superior, won't bother me). The most important thing is this: be prepared to experiment! If you don't like to experiment you're in the wrong hobby anyway - take up stamp collecting. If you don't like to fiddle around with a plane once it's airworthy then forget this. Trust me, you'll do nothing but tinker with a smoker. Get into that Zen Mad Scientist Mode, and prepare yourself for the grim truth that nothing really comes easy in this hobby, but you can have a whole lot of fun getting there if you're patient. As with most suggestions you're likely to hear about this hobby, take anything you read here with a grain of salt. None of this is the gospel truth, it's not written in stone or any such thing. If you ask four different people at the field about smoke systems, they'll probably tell you four entirely different things. It's not that any of them are entirely wrong (and probably they aren't entirely right either), but that smoke systems, like many things having to do with modeling, are an engineering challenge that can be approached from different angles. No two engines, installations, planes, prop/engine combos, mufflers, etc. are the same. What worked for me and your friend Joe Blow, may not do squat for you. I'm here to give you a starting point by telling you what's worked for me, and hopefully this can save you some aggravation. I've had luck getting engines as small as .40 size to smoke, but .60's are better. I've found four-strokes smoke better than a comparably sized two-stroke. My personal theory on this is that the smaller muffler on four-strokes in combination with the longer pause between exhaust cycles allows the smoke fuel to get hotter. You engineering types out there are more than welcome to comment.

Smokin'!

All smoke systems work essentially in the same way: pumping a smoke fuel from a separate tank into the muffler. The smoke fuel, on contact with the hot exhaust gases and muffler walls, burns creating smoke. Same thing is happening in that wreck you got stuck behind on the interstate the other day. You know the one, belching big clouds of smoke for your lung's appreciation (you gotta wonder how some of those things pass inspection), except in that case engine oil is unintentionally (I hope) leaking into the exhaust system through a worn seal, bad ring, or cracked engine block (and the slob wonders why he has to pour two quarts of motor oil in it each week!).

In general, a smoke system consists of the following: a separate smoke fuel tank and associated tubing, a smoke pump, a smoke valve that can be controlled via a spare servo channel on you radio system (needless to say, you need at least a five channel radio), a one way check valve, a needle valve to control the flow of smoke fuel into the muffler, and an optional fuel filler valve (if the pump isn't buried under a cowl you could just pull the intake line and fill it from there). This basic system diagram in shown in Figure 1:

The smoke fuel is drawn from the tank by the pump, and forced through the lines until it gets to the smoke valve. When the smoke valve is opened via remote control, it allows the smoke fuel to continue on down the line through the one way check valve and needle valve. The one way check valve allows fuel to flow in only one direction (Duh!) and is necessary to prevent muffler pressure from forcing the smoke fuel back up the lines. Many other modelers and some pump manufactures consider the needle valve unnecessary or optional, but I consider it a must. It's the simplest way to control the flow, and it's just not worth the hassle to do without it for the sake of a few dollars. Keep your fuel lines as short and straight as possible. Long lines make it harder for the pump to prime itself and reduces the flow rate, leading to long delays between the time you turn on the smoke, and when it actually starts coming out. Excessively long and twisty lines can render a smoke system totally useless.

The layout shown in Figure 1, while not critical, is ideal. As a general rule of thumb, you want the pump as close to the tank as possible to reduce delay times and make it easy for the pump to self prime. The smoke valve should be located after the pump so that the pump never goes dry,

smoke balls, they are novelty items
