How? 100 PSI, 1.25 inch PVC barrel. Look for the Youtube channel with my how it works videos. It is the same username as here. All is revealed there.

i got some video of some adding machine tape launches this weekend. i won't be able to post to youtube until later. Here are a couple of screen captures from the video for your enjoyment. The streamer is a full roll of adding machine or cash register tape.
Edit; added another photo from another shot. The pressure was cranked up the paper finished unrolling at altitude. We left the zoom out so you see what we see. That is a full roll of adding machine tape up there.
Added video of Friday afternoon's launch.

- We had a small breeze. The tape drifted over a 2 story building and the next building before landing next to the property line. The building is an old school. The roof in the photo is the roof of the gym.

- Tape is unrolled all the way.

- High pressure shot. Paper has altitude. That is the remains of a 130 foot roll of tape. Some tore off on the way up in little bill size pieces. The remainder is well over 100 feet long. Click to enlarge.
Some hard candy will fit in certain barrels. I know that some peppermints fit perfectly in 3/4" sch 40. I'll try to find a pic.
edit: quick google search
Peppermint twists
Also 3/4" copper pipe will fit OK in 3/4" sdr 21, I fill the copper pipe with wax for more weight.

Yes it's ether that or a squash ball I cant remember but it was going to be my first ammo for my 2" cannon but then I lost it. It fit absolutely perfect though!huse_spud wrote:this post is starting to get old but the ideas never end.
would a racket ball work with 2" pipe? that would be AWESOME if you could shoot it off in a room.

I've been looking at pipe ODs, and I found that 5/8" copper tubing has an ID of exactly .68, perfect for paintballs
I love lamp
This has probably been done before, but...
I just ordered 576 glow in the dark rubber balls, 27mm diameter.
Also got a bunch of 5mm UV LEDs, so I'm going to make a container with a few of those shining in on the walls, rechargeable battery powered, so when I go shooting at night I'll have a steady supply of LASERS hahaha.

Ok. I was thinking, what about regular super bright white leds? Just link em up to a few 3 volt button batterys and they will blind you.
Eh, they don't work so well. Phosphorescent pigments are charged by a specific chunk of the light spectrum. Specifically, long wave UV. Green light is neutral, red works against the charging effect.
Sunlight is normally the best, white incandescent light bulbs and fluorescent bulbs work pretty well too.
The reason sunlight, incandescent and fluorescent bulbs work well is they emit a broad spectrum, and do reach up into the UV band.
White super bright LEDs have a broad spectrum as well, but it stops short of UV. So, you wind up with a more or less equal balance of red and blue light, with no ultra-violet, and the overall effect is pretty negligible.
Or at least this has been my experience with them. Blue super brights work better than white.
One of these would do the trick, too.

I've had good luck with UV flashlights. 
I don't have a photo of mine handy, but it is quite bright for a UV flashlight. It is not bright in the visiable blue spectrum like many black lights are. Here is a shot of a PVC reducer painted with UV leak tracer. It is sitting on a white sink countertop.
In room light.
And here it is on a white sink lit with a UV flashlight. This is on the same sink.
I found the UV flashlight puts out much less blue light and more UV in a concentrated beam than a 4 W fluorescent.

They will also overheat and fry in about 5 seconds. That's what this and this are for. So far as optical tracking is concerned, I think the best we can do is photoluminescents and such. But if you really want to track a projectile, I suggest a smoke trail of some sort.warhead052 wrote:Ok. I was thinking, what about regular super bright white leds?
