Does the pump cap come off fairly easy?

My guess is no, you'll have to do something similar to what's done in the XP 150 link I posted above. But do report what you find, and please post photos here too for others in the future.

Welcome to WaterWar.net!

I don't think the Pulse Master is worth much. There are blasters in far higher demand like the old CPS blasters. You might get the most value from the blasters by giving one to a friend and having a water battle.

Welcome to WaterWar.net! I haven't seen an explanation of why the XP 105 has different sized pressure chambers. The patent iSoaker lists in his review mentions "tanks 188 and 189" (referring to fig. 2), but never says that the tanks can be different sizes as far as I can tell. I'd speculate that the...

Great range! Nice to see a homemade water gun with multiple bladders. I vaguely recall having trouble getting all the bladders to fill when trying that, though I don't recall that specifically so I don't know if I did ever try that. Interesting that the order is random. I'm going to have to try mult...

Nice find. I vaguely recall having a similar problem at the University of Texas at Austin. I wouldn't expect this pressure calculation to be accurate. My guess is that whoever made the problem wants you to assume that there are no flow losses and no drag, both of which are significant factors in the...

Found a goofy looking version of it on Ebay, will report back once it arrives This one likely is not good. I recall reading somewhere a while back that the ones with angled triggers are air pressure. That seems to be true for the WaterZone XL 3000 as you reported earlier. Keep it up, though, as it'...

Sounds like a nice war overall, and I'm looking forward to part 2.

Welcome to WaterWar.net. The Spyra One is probably the most powerful blaster on the market, but it's fairly expensive and apparently out of stock right now. (Full disclosure: I did some consulting for them.) Some of the copycat blasters are indeed good and comparable to the old CPS series. (Some see...

Very nice work. I recall being impressed your accumulator tank water guns before and that continues here. I'm also impressed with the trigger. I think the ergonomics could improve, but it's a step in the right direction. Which accumulator tank are you using for this? I might buy a similar one myself...

I have changed the plan to instead do the tests indoors. I have found a source of precision micro-scale apertures that I could use to scale down the experiments so that they will fit within the space available, and also hopefully not require particularly high pressures. I ordered a 50 μm aperture th...

We have an answer to this question on the old SSC frequently asked questions page , quoted here: Which gun is the best? Which gun shoots the farthest? Which gun is the best for this year? Which gun should I choose? "What is the best super soaker ever" is the kind of ambiguous question that you will ...

No, I haven't posted this before. I was keeping it under wraps for various reasons. I'm posting this with the understanding that this is a work in progress, and new experiments might invalidate it or adjust the constant. d_0 = (C_d* / R*_opt) * R In the equation above, d_0 is the optimal nozzle diam...

Is this something you could put into spreadsheet formulas and share via Google Sheets? Or Share via Google Drive if maintained in Excel instead of Google Sheets? The theoretical optimal nozzle diameter equation is quite simple. You wouldn't really need a spreadsheet for it but could use one if you ...

The posts above were made before the pandemic and seem rather distant now. :-( I'm planning some new outdoor experiments once it starts to warm up. The indoor vertical jet case is fairly limited by the ceiling height, and given that I don't have access to any building with a ceiling higher than 9 fe...

Ben, it would be good to have you close by! Did you get a position with a University?

I'm working for the patent office in northern Virginia, remotely for the moment.

Looks like a nice location. I found a map, though I'm not quite sure where each photo is: https://southcarolinaparks.com/landsford-canal/maps-and-brochures I'll be moving to Virginia sometime this year so maybe I could join you all in the future, but not any time soon. (Yes, it seems that the photos...

Thanks for posting. That spring mechanism is quite interesting, and a good way to reduce the pumping force. Almost reminds me of the proposals to use telescopic tubes of progressively smaller diameter to reduce the pumping force as pressure gets higher (I believe there are some existing e.g. bike pu...

Nice video. I'm impressed by the number of views in less than a week. I'd recommend linking to WWN as I think we need all the advertising we could get.

Hopefully my schedule will clear out next year and I can make a few homemade water gun videos of my own...

Great find. I suppose the female version of the same fitting will work for those who want a replacement for broken QFDs?

I saw some comments on the photos. Did you post this elsewhere? I'm always looking to find others interested in water guns.

Living in Hawaii without A/C my wife and I have water gun fights to cool off. For battles my wife prefers the one I made her in on the bottom left with the red band of duct tape across the tank because it's powerful and much quicker to pressurize than the larger CPS guns. She also likes the Spyras ...
