All aboard the Madagascar Institute's jet-powered merry-go-round! (Thanks, Benjamin!)
#14: It’s similar the starter motor on your car. The engine won’t ignite unless it’s already spinning, so compressed air is used to set it off. I guess a leaf blower is a handy source of quite high-speed, directable air? More on wikipedia: http://en.wikipedia.org/wiki/Huffer
This is reckless, dangerous, possibly suicidal, hilarious, brilliant, wonderful, and a host of other adjectives. I love it.
In my mother’s imagination, this is every carnival ride ever made.
SRL has some sweet pulse jet action
i built model aeroplane driven by a jet, but nowadays, its probably insanely illegal and a fire hazard.
the new zeland jet cart? cool
the merry go round? SUPER cool
Dr. Darwin will see you now.
if only it were monkey navigated!
Their helmets are the best part.
“It’s just crazy enough to work!” And it did. Thanks, Mark.
You know, I’d rather die experimenting with a jet-powered merry-go-round than to go out in some senseless tragedy.
But that’s just me.
ThatÂ´s so awesome that I can barely say one word: WIN!
looks like something straight out of garry’s mod
NASA plans to duplicate this for only $2.5 million as another possible shuttle replacement.
Hahahaa … looks like they have a regular car brake setup at the top to slow it down?
Now THATS funny!
That was dissapointingly short on violent acceleration.
Was I the only one hearing the strains of Still Alive: “This was a triumph…. We do what we must because we can…”?
fantastic! for version 2.0 i would like to see flames coming out of both of the horsies.
I have one in my back yard.
Geeks will be geeks, I guess… Very cool.
Some people have more pulse jets than they know what to do with.
Powered by equal parts awesome & crazy. I’m going back to do a belated degree next year – I think I’m gonna go hang out in the engineering dept & cause trouble…
Not nearly as fast as I was expecting, fortunately for them.
That’s not jet powered, it’s propeller powered. 3 times less cool.
So, the merry-go-round goes merrily round until President Madagascar gives the order to “SHUT DOWN EVERYTHING”…
A few years ago the dreadlocked guy operating the ride from the middle blew his own face off building a confetti cannon. A couple years before that he ripped it apart removing a suspension spring without a spring compressor. So the sign at the beginning of the clip is not to be taken lightly…
That aside, cool ride!
omg.. that thing is INSANE!! haha ya see something new every day!
Good lord. I’d be a puke sprinkler about 10 seconds into that.
So they can build that thing but not a tripod for the camera?
Question though: why is the thing ignited by a leaf blower?
I just love pulse jets… too cool. And loud. Real loud.
But, boy, does this remind me of the Golightly Steam Rocket… just tethered…
The jets are valveless pulsejets, which work like the old V-1 buzzbombs but without moving parts. The combustion chamber is the thicker part of the tube. All pulsejets (AFAIK) require airflow to get started. (V-1s were launched from catapults or dropped from airplanes because they couldn’t launch under their own power.)
“You must be at least this deaf to ride the carousel. If not, you will certainly be so afterwards.”
ah, to be 11 years old again, like these guys.
Really like the safety equipment used for this. I would have at least used bicycle helmets to give the illusion of safety. It would make their mothers feel a tiny bit better, when the flame from the first unit sets the rider on the second unit on fire.
That is a thing of demented beauty.
Judging from the angles they pulled about 3 Gs. Not a ride for sissies!
You can get the same effect by eating a couple of bean burritos before getting on the ride.
Anon11, not propeller powered. Where do you see the propellers?
“removing a suspension spring without a spring compressor.”
Ouch. I bet the $40 that a spring compressor costs looks really, really cheap to him now.
AWWWww, it didn’t FAIL.
that’s not nearly as entertaining.
