Interesting Way To Launch Fireworks

oritteropo says...

The description from one of the other slingshot rocket launcher vids is:


Launching rockets in Germany requires all kinds of permits and licenses nobody ever gets. But for just 48 hours each year, the rules change. During these two days, every adult person is allowed to blast away with rockets and fire crackers!

The Slingshot Channel MUST take advantage of this once-in-a-year time slot. This time, we built a 2,5 meters high rubber based launch tower, capable of launching an unlit rocket about 50 meters up in the air! Add these 50 meters to the 60-80 meters that the rockets achieve by means of their powder charge, and you get some serious total height.

Of course many things can go wrong. The flimsy wooden shafts are not made to endure the stress of 50 kilogramms (110 lb) of a draw force applied by the rubber bands, and can break right in the barrel of the launcher. Also, if the timing of the fuse is bad and the charge ignites when the nose of the rocket is already pointed downwards, then the rocket will be propelled downwards and explose at ground level - effectively a surface to surface missile.

The Slingshot Channel tests all this... come and see the results!


It seems to be the season for it, people here are still letting off illegal fireworks 24 hours after New Years Eve (and they started several weeks before Christmas!).

That video also explains what's going on, it was his test run during the day:

True, and there's no better a way to learn to appreciate the wonders of rubber bands than through healthy discover like these two here, Welty and Snappy

What your analysis is missing is any kind of cultural context. These things don't just happen in a vacuum, and nor are all ideas created equal. In many cases you are just trading one type of chain for another. Yes, mass media certainly has the ability to create and shape the prevailing social norms, and this can inspire counter cultural movements within a society. That's what happened in the 1960s with the sexual revolution, which is a root cause for the sexual immorality we see in society today. But it didn't just happen because people 'gained more knowledge', it happened because there was already a fundamental shift in the cultural ethos. An idea does not begin to grow unless its seed lands on fertile ground. The social mores of this nation were always decidedly Christian, but were steadily eroding by the beginning of the 20th century (for various reasons). The deeper truth is that people rejected traditional morality because they wanted to be free to indulge their carnal desires without restriction. Transcendent moral values were being replaced with moral relativism, fueled by the notion that man was a higher primate and had no moral responsibilities to a creator, leaving people free to invent whatever style of living pleased them. It was only the world wars that temporarily reversed this trend and brought the nation back together under the banner of an American moral imperative. But the foundation, weakened as it was by radical liberal ideology, was thoroughly rotten. America snapped back like a rubber band, bursting open the flood gates during the 60's, and changing the cultural landscape forever. Now traditional values are viewed as archaic, a throwback to a bygone era, and it is the "new" thing which is touted as "enlightenment".

Yet, this new thing is simply what is old in different packaging. The behavior of human beings today isn't noticeably different from anything that hasn't been tried in countless failed civilizations in the past. The song remains the same, despite the shiny new backdrops. Bible prophecy predicts that knowledge will increase in the last times, but it mentions nothing about wisdom. The human condition hasn't changed; men are ruled by their passions, and no matter how much knowledge they gain, the same mistakes are repeated endlessly. Look at the world today and tell me that isn't true. If humans are learning anything it is something they've always known and loved; rebellion. This is certainly the age of self-glorification, but history will tell you that is nothing new either. You're right in that "the church", ie, the catholic religion, tried to impose (a caricature of) Christian morality on the masses, with horrific results. That is a nightmare any decent person should be awoken from. However, as it pertains to describing the essential human condition, it was entirely correct. Sin is increasing in the world, not decreasing. Human nature is inherently sinful.

Everyone has a different way of describing the problem. Most look to place the blame and hand wave everything on to a particular condition. They say it's because of overpopulation. They say it's because of religion (an atheist favorite). They say it's because of ignorance. They say it's because (insert your favorite reason here). The reality is, it's because human beings are corrupt sinners, and always will be corrupt sinners until the end of time; that's why Jesus Christ came. He came to restore us to right relationship with our Creator. Don't place your faith and trust in man, because man cannot save himself, and all men are headed for a day of judgment. As scripture predicts, there will be a one world government headed by the antichrist, a seven year tribulation where all the world will become deluded and follow after the beast. Those who refuse to love the truth will believe the lie that the antichrist will be selling. At the end of the tribulation, Jesus Christ will return as the Lord and judge of all the earth. No amount of knowledge will prepare for you that day; only a saving faith in Jesus Christ.

There are two predominant theories (last I knew anyway). One says that the universe will expand to such an extent and cool to such an extent that it will eventually just fly apart. The other is the idea of a rubber-band that eventually it will fall back in on itself. Right now what is baffling is scientists really don't know enough about what the energy is that is pushing the universe apart or even if it's what they think it is. I suspect whomever answers that question will get the next Nobel.

>> ^packo:

u assume there is something outside the universe to expand into
there is literally nothing... think of the universe like a rubber band... stretching


Could say the same thing about what you stated. The ASSuming part

That is unless you can back that up with something, and I do want you to ( as I am interested).

Guy builds crazy slingshot that fires circular saw blades!

shuac says...

Meh, why can't he make such a system where the dowels are attached to the rubber bands, thus releasing the blade and only the blade? Better yet, get rid of the rubber bands altogether in favor of a gas-pressurized system that incorporates a reloading, semi-auto kind of thing.
