You could add about 2 feet of twine behind it and dip it in the liquid from a glowstick, then just shoot it at night, I can't think of an easy way to make a golf ball glow, the liquid prolly wouldn't stick to the ball. You could also glue a cotton ball to the back of the golf ball and dip that in the glow stick liquid.

i may start to look for one of the glowing balls.

(Jsr got his answer in that link)

BTW, i would go green if you can cause i think the human eye is most sensitive to the color green

is there a easier way to find it?
like if i chrony it and messure the angle and do something with those numbers..
Yes, you can talk to me. Although my range calculator isn't public release yet, it is mostly working, so I can give answers for things like this.

I've looked it over, and using a variant of the Gs drag model, my guess is that because of the poor drag characteristic of a golf ball, unless you induce backspin, even at 2400 fps, you're unlikely to fire said ball more than about 500 or 600 metres (depending on the angle).

Spheres aren't good supersonic projectiles, and they'll slow down from 2400 fps to below 1000 in the blink of an eye.
It'll do about 200 or 250 feet of flight in that time - a healthy distance, but if you consider that the extra 1400 fps contributes less than a 100 yards extra range, you'll recognise the diminishing returns involved.

The goal of a mile golf ball shot is an impossibility, because in order to fire a golf ball that far, the ball would have to be fired so fast the friction from drag would cause it to immolate.

With backspin, obviously you'll gain range, but it won't triple the distances to your desired mile-plus ranges.

I don't think you'll need to worry about methods of finding a golf ball that's flown a mile, because it's not going to go that far - sorry, but it's the truth.

intresting.

to talk more about that i PM you tomorrow. (to get numbers on a barely supersonic 600g lead slug.) i will send you pics etc so you can model it.

not a golf ball, but when I want to test range I use smokebombs

as far as the golf ball, try painting it florescent orange

Brings back memories of the 50km/s tennis ball, doesn't it? :lol:
The goal isn't impossible, you'd just need a 1 mile long vaccuum chamber.

micro: almost nothing electronic will survive through that barrel. it has 30000G's
Haha Okay then.

lol. for my spud gun, i borrowed a sensor off the school and used that. it measured a speed of 571.9km/h for a tennis ball. running off purely start ya bastard. basicaly aerostart but its a higher ether concentration 25% instaed of 24%. lol

fear

I think using a glowing GB at night would be your best bet. Whether you do this by using the commercial glowing GB, insert a glowstick, or spray/drench it with glowliquid, thats your choice.

The perfect way of finding it would be to place a radioactive material in the golfball and then using stuff to track it up after shooting it. But how would you get access to radioactive material? :P

@spudfarm: Got your PM, but I'm short on time right now, so it's going to have to wait.
