View Full Version : New bong idea (I think)

What about having an extra tank on top of the bong made out of the same pipe and connected something lie this;

The box on bottom is a pump and the odd shape about half-way up the pipe is the showerhead. The circles are where barbs will go and the black circles under the tank are holes for the steam to escape.
The extra water tank would be airtight and would lead to a barb at the water level. This way, when the water goes below the barb, it'll let out water until the water gets above it again. I got the idea here (http://www.overclockers.com/tips667/).

If the upper resevoir is no longer airtight then all the water goes down and out all over the floor, ext. Why not just double the resevoir size at the bottom, or better yet, use a big bucket?

If the top is airtight, what would you think?
I think that having all that water at the top is going to make the thing very top heavy and it will tend to fall over.
Frankly there's no advantage to having the extra tank on top. Just put the same amount of extra pipe on the bottom and make your resevoir bigger. That will have the added benefit of giving you more thermal mass in the resevoir.

It would look very cool though and you would have bragging rights. heheh ;)

I see no reason why it wouldn't work, just as long as the top is airtight. Actually, to make it really good, you could make it with a bigger tank and the reservoir. Then you could have the best of both worlds.
Right now on mine, I have a 64oz bottle sitting on my case which is right by my tower. I've gotten it to where I don't have to check my level for about a day and a half, which is nice when I leave town for a while.
if you decide to make it, good luck!
Ok, I must be missing something here. If you're building a bong from scratch, what's the advantage in having the extra resevoir rather than just having a single larger one? The only advantage I can think of would be if the secondary resevoir were somehow easier to fill.
In an existing bong there's a reason to add a secondary resevoir. The added volume of water gives you extra assurance against running out. Running out is a danger given the evaporative nature of bong cooling.
But given that all that matters is the total volume of water, why go to the hassle of building two resevoirs with a feeding mechanism instead of building a large single resevoir. Is there some advantage to having a smaller working resevoir that I'm missing? Or is it just niftier to have 2?

oh, I thought they were supposed to be called "water pipes"....

Hey nihili,
You're right that it has yet to be built. You might have a point about having a single big reservior, but somehow it seems counterintuitive to have one big tank on bottom. It may just be the cool factor and having extra tubing. I dunno. Thanks for the thought. If it seems that your idea would be better, then it'd be quite a timesaver. I'm glad that I like to think things out.

i thinkit would just fall over, only advantage i could see is if people really dont want to bend over

The way i see it, if im correct is the hot water straight out of water block goes to upper reservior... cools off a bit while it sits there, before going through the shower head.... so overall it should make it run a little cooler.... ideally the lower reservior would be very small, so the water doesnt get time to warm up in there.

Ok, you're seeing the top resevoir as a gravity feed for the shower. In this case you'll need to make sure that the gravity feed matches the flow rate of your pump, otherwise the top resevoir will either run out of water or overflow. This will take some tweaking to get right. You do have a little leeway to play with as the pressure from the top resevoir will vary with the amount of water in it. My guess is that your pump will out do to the pressure from gravity feed, but that should be easy enough to calculate. It will be harder to figure out what the net flow of each is after adjusting for resistance.

Looks like I should have drawn a bit better.
The extra tank on top feeds into the lower reservoir when the water level in the lower reservior goes below barb coming from the extra tank on top. The hot water from the CPU (not drawn) goes directly into the shower head. The steam then can escape through the holes above the shower head (black circles in the drawing) or through the open section of the sanitary tee.
I put holes above the shower head in case I decided to put a low-power fan in the tee to get steam out faster.
Sorry about the confusion.

That's what i got from the drawing.

Ok, although it seems from your last post that I forgot to mention that the extra tank is airtight. That way I don't have to do any calculations about flow, resistance etc...
Water will only flow into the reservoir while there's a way for air to get in and displace the water. When the water goes above the barb, no air can get into the extra tank to displace the water and therefore no water can escape.
Sorry if you're screaming DUH! at your computer. I want to make sure that people will know what's going on.
Now that that's cleared up, I'm getting some other ideas on how to make a larger and more stable water tank. Go figure.:rolleyes: I'll make sure and bounce any ideas around here. Thanks for you input.

New idea, per your suggestion, nihili;
http://imagehost.auctionwatch.com/preview/id/ideamagnate/.mids/bong.JPG
Bucket refers to the rectangle in bottom and the blue arrows indicate the flow of the water.
Obvoiusly I'll get more water, more stability and a simpler setup than with my previous idea. My only worry is the capacity of my pump, an Ehiem 1250. The distance up my computer is about 18" and the total height of the bong is variable. How high should it be so that I can still get a decent amount of pressure, and how much pressure should I try for?

Damn, I thought you guyz were actually talking abour REAL BONGS!!
So this is for a wateer block? um..........Whats a water block?

Perhaps you misintreperted the discussion on the first dozen posts.
This (http://www.overclockers.com/articles389/) is what we're talking about and this (http://www.wizard.com/~scfoster/wbasic.html) is what a water block is. There are better links if you want them, but our bongs aren't nearly as much fun as yours.
Anyway, back to the subject...
