Nitro lacquer is a standard finish that's been in use for decades. It's whats used on all guitars, etc...

I don't think the finish product itself is as explosive as you think. But I did follow all of the recommended safety procedures about inhalation, etc (I ain't dumb).

I used it because I wanted to spray thin coats to get the type of look I wanted. Also, I do a fair amount of stringed instrument repair, and working with the stuff is a skill I needed to acquire at some point. It was really easy to do, in fact. Way the hell better than the experience I had with traditional furniture finishes like minwax crap. Instruments use it because it screws with the sound properties in just the right way (not the old school violin guys... they swear anything other than an oil finish is crap, even if it takes 2 months to dry).

Good point. No sound minds in water polo. But there is a giant indoor pool nearby.

I turned on the car heater and it was in the 50Fs last night. Winter is here, and it's only September.

Well, I was just pulling your chain, but in fact nitrocellulose is horrifically flammable and also explosive. Photo and movie film used to be cellulose nitrate (aka nitocellulose) until one too many movie film storage facilities burned to the ground. Many one-of-a-kind archived movies were lost to posterity that way. Fortunately around that time cellulose acetate had been developed, and the switchover could be made. The giveaway is the nitro, you know, like in nitroglycerine, its first cousin, and TNT, trinitrotoluene. Pretty much anything that starts out nitro- will be explosive to some degree.

Nitromethane, good race car fuel. Explosivity seems to stem from multple nitro- groups on the same molecule as in TNT, nitroglycerin, nitrocellulose, etc.

Hey, there's a hole in the road.

rjones28 

Is that a sink hole?

Okay. Coffee and whisky.

* One Top Fuel dragster 500 cubic-inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.
* Under full throttle, a dragster engine consumes 11.2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.
* A stock Dodge Hemi V8 engine cannot produce enough power to merely drive the dragster’s supercharger.
* With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders run on the verge of hydraulic lock at full throttle.
* At the stoichiometric 1.7:1 air/fuel mixture for nitro methane the flame front temperature measures 7050 degrees F.
* Nitro methane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.
* Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
* Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow.
* If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half.
* Dragsters reach over 300 MPH before you have completed reading this sentence.
* In order to exceed 300 MPH in 4.5 seconds, dragsters must accelerate an average of over 4 G’s. In order to reach 200 MPH well before half-track, the launch acceleration approaches 8 G’s.
* Top Fuel engines turn approximately 540 revolutions from light to light!
* Including the burnout, the engine must only survive 900 revolutions under load.
* The redline is actually quite high at 9500 RPM.
* THE BOTTOM LINE: Assuming all the equipment is paid off, the crew worked for free, & for once, NOTHING BLOWS UP, each run costs an estimated $1,000 per second.
The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter-mile (10/05/03, Tony Schumacher). The top speed record is 333.00 MPH (533 km/h) as measured over the last 66′ of the run (09/28/03, Doug Kalitta).
Putting this all into perspective:
Lets say the you are driving the average $140,000 Lingenfelter twin-turbo powered Corvette Z06.
Over a mile up the road, a Top Fuel dragster is staged & ready to launch down a quarter-mile strip as you pass by it. You have the advantage of a flying start. You run the ‘Vette hard up through the gears and blast across the starting line & pass the dragster at an honest 200 MPH. Just as you pass the Top Fuel Dragster the ‘tree’ goes green for both of you.
The dragster launches & starts after you. You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums & within 3 seconds the dragster catches & passes you. He beats you to the finish line, a quarter-mile away from where you just passed him. Think about it – from a standing start, the dragster had spotted you 200 MPH & not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race!

When it was built, the arena behind the stadium was way over budget, in part due to sink hole issues.

Just want to point out that it's National Coffee Day.

I'm celebrating with a 3 shot Americano and a 4 shot iced frappe.

I may need a designated driver.

rpenmanparker 

What's your point? Let's talk about something really important. Can you fool around in the back seat of either car?

Man, those were the days. I can almost remember them.

Between the two of us maybe we could piece together a rough recollection of how it was supposed to go. Just love that Bob Seeger. "Wish I didn't know now what I didn't know then."
