Hold the bottom of the bag open with crossed drinking straws (you will need to jam one straw into another to make them long enough), and carefully drip some wax onto the straws as candle mounts. No one would want to try this, say, on a beach at night with an offshore breeze, because a puff of breeze will fold over the top of the bag and it will catch fire, plunging into the sea and endangering the turtles. There is also the danger that the Asbury Park Press will report that the UFO "glowed red and hummed". Kevin Gallimore |

Ed Huntress I made my paper balloons from instructions in a magazine that described how to lay out the gore pattern for a sphere. Polyethylene cleaners bags worked almost as well for minimal effort, and didn't alarm the neighborhood with a bright flame when they ignited. IIRC the ring was split bamboo and the cross wires were strands of picture hanging wire. I hung them on a tall stake to inflate them with a tiny campfire and then put alcohol-soaked cotton balls in the aluminum foil cup for the flight. The flame made the balloon glow like a Japanese paper lantern. This is a good description: http://www.ufoevidence.org/Cases/Cas...cle.asp?ID=427 That one wasn't mine. At that time I was pulling my pranks in college a few towns away. A hot-air balloon could lift a few cells from a disassembled 9V battery and these light bulbs : http://www.advantagehobby.com/137114/MDP391/?pcat=1316 or series-string (low voltage) Christmas flashers. |

But a good on line calculator would take the rolling resistance into account. Dan I was lazy and looked for a calculator first. But I don't know the source and so I didn't trust it. The equation is something I had on hand. So, to check the online calculator, I cancelled out the factors that would be the same at different horsepower ratings and speeds on one particular bike (Cd, A, k) and realized that the equation simplifies to something trivial, IF you know both one particular speed and the horsepower required at that speed. Which happens rarely, but fortunately there is a lot of documentation about it online because of the unusual agreement between Kawasaki and the EU to speed-limit the bike to 300 km/hr. The magazines all wanted to know what it will do without the governor, and there are several road tests that came up with the 200 mph figure. And that also happens to make sense in terms of the factors I cancelled out. Those are pretty typical for a big bike with advanced streamlining, like the Ninja. Notice that the Honda that went 270+ did a bit better with less horsepower (270 with 400 hp vs. 265 with 450), which also makes sense. That Honda is engineered for one thing: setting a world record at Bonneville. Its Cd probably is lower than that of any street bike. Anyway, the online calculator checks out. Try varying the weight of the bike a bit and see what the consequence is for different values of rolling resistance (that's where the weight factor comes into play). The speed varies very little, you'll notice. That also makes sense. -- Ed Huntress |

I'm thinking that the engine won't run very well. Now, I'm sure that if the compression was changed, and the carb re-jetted, and the cam changed, things might work better. But if all you do is change fuels I think there won't be much of an increase. This is of course in response to gunner's assertion that he was clocked going 264 mph on a bone stock Ninja motorcycle burning nitro methane fuel. I don't think the motorcycle could develop enough power to push itself and someone sitting on it to over 200 mph no matter what kind of fuel it was burning. ERic Bone stock? Who the hell made that claim? It was a heavily modified custom engine that may or may not been built by a guy who later busted the land speed record on an improved verson. Might even have been the same bike..shrug. Or not. SNIP Correction: Mark Weiber (AKA Gunner) said "stone custom engine" and I read this as "stone stock engine" which I further morphed in my brain as "bone stock engine". My mistake and I stand corrected. There is still no ****ing way he rode any motorcycle as fast as 264 miles per hour. Mark, how about you get the guy who's bike you supposedly rode 264 miles per hour to confirm you actually rode it that fast. Or that you even got to sit on it while it was parked. I apologize for making the mistake about what you said in the first place. But Mark, your story was so fantastic that I guess I embellished it in my mind. Why do you post stuff like this anyway? Nobody believes a word of it and you must realize that. Why not just write a book about some kind of superhero? Everybody will know it's a work of fiction and you can spin all sorts of tales and maybe get paid for it instead of looking and acting like a fool. Nobody takes the James Bond movies seriously but they sure are fun to watch and make lots of money. Take advantage of that. How can you expect folks to take you seriously when you talk about stuff you do know about when you keep posting so much bull**** and presenting it as the truth?

VBG 23 Dollar pit? *Tell us!! 23 $ pit is a cave in North West Alabama that was found by Bill Torode. Bill gave it that name because he lost $23 somewhere in the cave on one of the first trips. It is called a pit because that is what it is. It is a large sink hole maybe 150 feet across and an eighty foot drop to the floor of the pit. So you start out repelling down 80 feet, but then you move off to the right and go down another 20 foot drop using the same rope. And then you move off into the cave. As I remember the story , when Bill first found the pit , there was no rope available. So no exploration was done. But of course they came back another day with rope. And explored the cave. Well not all of it. The upper section is not real large, but not too far from the entrance was another pit, about 60 feet. And so that trip only explored the upper level. But cavers are persistent. And they came back on another trip with more rope. But not enough. As there was yet another pit. This one about 160 feet. And so they had to come back again. And I was in the group that finally got to the bottom of the cave. We carried lots of rope and used most of it. We left early to get to the cave and stayed late. As I remember we were in the cave about 13 hours and repelled down over 400 feet. Actually repelling down is easy. It is the climbing up that is hard. I was using Asender knots and the rope at the 160 foot pit was a bit dirty with clay . I got about 90 feet up and couldn't go any higher. I would slide down about as fast as I could climb up. Bill tied his Jumars to the bottom of the rope and I pulled them up and changed to the Jumars. He let me use them on the remaining climbs. I am not sure if it was because he thought I needed the assurance of using Jumars or that he just wanted me to climb faster. So I am one of the few, possibly only caver, that has done over 400 feet of vertical caving in Alabama without doing pit in Fern Cave. Dan |

Bill gave it that name because he lost $23 somewhere in the cave on one of the first trips. It is called a pit because that is what it is. It is a large sink hole maybe 150 feet across and an eighty foot drop to the floor of the pit. So you start out repelling down 80 feet, but then you move off to the right and go down another 20 foot drop using the same rope. And then you move off into the cave. As I remember the story , when Bill first found the pit , there was no rope available. So no exploration was done. But of course they came back another day with rope. And explored the cave. Well not all of it. The upper section is not real large, but not too far from the entrance was another pit, about 60 feet. And so that trip only explored the upper level. But cavers are persistent. And they came back on another trip with more rope. But not enough. As there was yet another pit. This one about 160 feet. And so they had to come back again. And I was in the group that finally got to the bottom of the cave. We carried lots of rope and used most of it. We left early to get to the cave and stayed late. As I remember we were in the cave about 13 hours and repelled down over 400 feet. Actually repelling down is easy. It is the climbing up that is hard. I was using Asender knots and the rope at the 160 foot pit was a bit dirty with clay . I got about 90 feet up and couldn't go any higher. I would slide down about as fast as I could climb up. Bill tied his Jumars to the bottom of the rope and I pulled them up and changed to the Jumars. He let me use them on the remaining climbs. I am not sure if it was because he thought I needed the assurance of using Jumars or that he just wanted me to climb faster. So I am one of the few, possibly only caver, that has done over 400 feet of vertical caving in Alabama without doing pit in Fern Cave. Dan Cool!! Is there a known bottom to the beasty? The methodology of the left has always been: 1. Lie 2. Repeat the lie as many times as possible 3. Have as many people repeat the lie as often as possible 4. Eventually, the uninformed believe the lie 5. The lie will then be made into some form oflaw 6. Then everyone must conform to the lie |

Cool!! Is there a known bottom to the beasty? Yes. We got to the bottom and mapped all the passages. Now it up to the readers to figure out how much of the story is true and what parts are false. I will wait for the results before posting about " Dan's Crawl Cave ". This time there is only Bill and Dan involved. Dan |

I'm thinking that the engine won't run very well. Now, I'm sure that if the compression was changed, and the carb re-jetted, and the cam changed, things might work better. But if all you do is change fuels I think there won't be much of an increase. This is of course in response to gunner's assertion that he was clocked going 264 mph on a bone stock Ninja motorcycle burning nitro methane fuel. I don't think the motorcycle could develop enough power to push itself and someone sitting on it to over 200 mph no matter what kind of fuel it was burning. ERic Bone stock? Who the hell made that claim? It was a heavily modified custom engine that may or may not been built by a guy who later busted the land speed record on an improved verson. Might even have been the same bike..shrug. Or not. SNIP Correction: Mark Weiber (AKA Gunner) said "stone custom engine" and I read this as "stone stock engine" which I further morphed in my brain as "bone stock engine". My mistake and I stand corrected. There is still no ****ing way he rode any motorcycle as fast as 264 miles per hour. Mark, how about you get the guy who's bike you supposedly rode 264 miles per hour to confirm you actually rode it that fast. Or that you even got to sit on it while it was parked. I apologize for making the mistake about what you said in the first place. But Mark, your story was so fantastic that I guess I embellished it in my mind. Why do you post stuff like this anyway? Nobody believes a word of it and you must realize that. Why not just write a book about some kind of superhero? Everybody will know it's a work of fiction and you can spin all sorts of tales and maybe get paid for it instead of looking and acting like a fool. Nobody takes the James Bond movies seriously but they sure are fun to watch and make lots of money. Take advantage of that. How can you expect folks to take you seriously when you talk about stuff you do know about when you keep posting so much bull**** and presenting it as the truth? Eric Very good points. Without rejetting the "stock" engine won't run at all on nitromethane |
