OMG nostalgia! I lived not even 20 minutes from there when I was a kid. I almost got killed in the parking lot there on the 4th of July once when a firework exploded right after launch and sent fiery fragments out into the crowd (one of them smashed the windshield of the car next to me). I also remember totally wanting to go on the Cannonball loop but my parents wouldn't let me (in hindsight probably a good decision on their part).

Motorworld there was awesome--it was across the street from Action Park and I think run by the same people. They had these cage-enclosed go-karts tanks equipped with compressed-air tennis ball cannons and sensors that stopped the tanks temporarily if they got hit by a tennis ball. You could pay to drive the tanks around inside an enclosed arena or you could also shoot at the tanks from the outside of the arena using air-cannon turrets that required quarters to operate. Tons of fun.

Mostly, though, I went to the water park, which according to Wikipedia had the most casualties. I got a fair amount of scrapes from the waterslides and I can totally see how people could get seriously injured on some of them.

I could see how one might think the dashcam owner set it up. He certainly sounds like he makes a "boom" noise before it happens.

If that were the case, beyond anything else I'd say it's not abuse, but an irresponsible prank. He/someone probably thought it would be funny to hide a container of compressed air in their trash is all.

(device seemingly powered by compressed air)

"At high speeds this precooler cools the hot, ram compressed air leading to an unusually high pressure ratio within the engine. The compressed air is subsequently fed into the rocket combustion chamber where it is ignited with stored liquid hydrogen. The high pressure ratio allows the engine to continue to provide high thrust at very high speeds and altitudes. The low temperature of the air permits light alloy construction to be employed which gives a very lightweight engine — essential for reaching orbit." —WikiPedia

It will surprise you how quickly your pc will accumulate dust, hair, and fuzzies like this one did. Best scenario is the overall lifetime of the pc will be diminished (heat is a computer killer) and worse case is a short circuit in the box catches the nasties on fire and your house burns down.
If you do (and you should) want to clean out the dust then I suggest using canned air or a camera dust blower. Vacuum cleaners can build up a static charge that will wreck the computer if you aren't careful. The compressed air like these guys use is awesome for filling tires but there always seems to be water (condensation?) in the take that comes out when you use it.
This is just my advice based on personal experience so think of it as law take it with a grain of salt, I am sure others have had better luck but I wouldn't take the risk.

It's more weird that SOME old computers are fairly clean inside even in the same place!

So it's running on compressed air? I wonder if you could make it run on petrol? I guess you'd need miniature spark plugs and a distributor.


That would be my guess.
Beyond the problem of building a tiny, tiny, tiny coil--a spark gap of a few microns would be problematic (at best).

Comment hidden because you are ignoring dag. (show it anyway)

Fantastic. Reminds me of my wife's granddad, so is very moving for me. I'm going to tell you about him because I can, you don't have to read this, it's just that I think he deserves a mention.

He retired at 65 from a career as an engineer and went on to be a tinkerer and inventor. He had a love of steam engines and built a scale model of Stephenson's Rocket in very much the same way as the gentleman in this video, but he made absolutely everything from scratch, including the nuts bolts and washers. It's about 12inches long and runs around a track when connected to compressed air. It still fascinates me to this day. He finished making it when he was 93. He said he'd sometimes drop a piece on his study floor and it would take him most of the day to find it again with his bad eyesight and loss of feeling in his fingers. I can't imagine having the skill to make one now while I'm in my prime. Seeing things like this make me feel awfully humble.

His crowning achievement was making the world's first ever road-legal solar powered car. He liked tinkering with solar power and realised that if he made a solar powered car it would be fun and he wouldn't have to pay road tax (he built and drove an electric sports car to work and back in the 50s for the same reason). So he built it. He wasn't the first to use solar power, he was just the first to make it road legal. I don't think he knew at the time he was the first, and it didn't seem that important to him. It was just something interesting to do. I swear he could have lived to 200 and not run out of ideas or things to do. He makes me realise how little I've done with my life.

If anyone's still reading and is still interested, this is him:

That was in Montreal, on Wolfe Street, between Rene-Levesque and Ste-Catherine. Because of the sudden rains we had on Monday (30 mm in 45 minutes), the manhole backed up and with the pressure of the compressed air, turned it into a geyser!

Thats when my gills come in handy. =)

Ah. I am surprised adult cats still have this.

Actually, ever been in a strong wind, or had compressed air blasted at your face? If you have a hard time breathing properly, that's due to the same reflex in babies that causes them to expell from their lungs when their faces hit air for the first time.

Ew. Yes, I can't breathe in winds.

^to be clear, macs aren't any easier with this.
White Unibody MacBook :
1 - Remove 8 screws from bottom
2 - Remove bottom case
3 - Blow compressed air into fan
4 - Do the opposite of steps 1 & 2 in reverse order


That can potentially cause ESD if you use the compressed air. use an antistatic vacuum next time

>> ^residue:
The heat from the hairdryer lulls the trunk gremlins into a false sense of security and they become comfortable and drowsy. They are, however, terrified of cats and when they hear the hissing of the compressed air, they mistake it for a pack of angry cats due to their decreased awareness. Enraged, they begin kicking violently in a frenzy outward on the dent, which pops back out.

Explanation anyone...?
:?



Bullshit. No such thing as trunk gremlins. Nothing lives in a car's trunk...
