When Graham and Ashkahn get to definitively answer a question, it’s like Christmas. Birds sing and the guys bust out their “Answering a question definitively” dance, which has the added side effect of better crop yields during the coming harvest. It’s an exciting time.

There’s a very straightforward mathematical equation for measuring the weight of salt water based on specific gravity, which is excellent. And useful!

Also, whoever wrote this question needs to contact Graham and Ashkahn ASAP!

Transcription of this episode… (in case you prefer reading)

Graham: Today’s question is, “how much does one gallon of Epsom salt saturated water weight? And, can I ever speak to you about an idea that I think would revolutionize the industry if you could help me to dream it possible?”

Ashkahn: That was part of the question?

Graham: Yeah. You wanna just do the first part first or-

Ashkahn: I guess so. Is that where the question ends or do they go into what the idea is?

Graham: No, they just want to know if they can speak to us about their idea.

Ashkahn: Oh, man, okay.

Graham: So, I guess the answer to that is yeah.

Ashkahn: Totally, yeah.

Graham: Definitely, yes. We love hearing ideas.

Ashkahn: I’m excited now. I wish they’d have written the whole thing in there.

Graham: I mean, it could revolutionize the industry.

Ashkahn: I can see how they don’t want us just broadcasting that out there.

Graham: Which I would have because obviously I’ll just read whatever’s in front of me.

Ashkahn: So, yeah, whoever this is, reach out. Get in touch.

Graham: Yeah man. Shoot us another question.

Ashkahn: Yeah, we’ll say it on the podcast. We’ll tell everybody your idea.

Graham: Unless you don’t want us to. In that case, we definitely won’t share it. So, the first part though, how much does one gallon of Epsom salt saturated water weigh? It’s not too hard to figure out.

Ashkahn: Yeah. It’s more than a gallon of water weighs.

Graham: And there you have it. You heard it from us.

Ashkahn: Okay. So, if you guys have other questions, you want to-

Graham: So, fortunately, the conversion with specific gravity of figuring out the weight of something is not the hardest thing in the world. It’s actually pretty simple. Just multiplication problem of you take the specific gravity and multiply it by, say the weight of water, which is 8.344 pounds.

Ashkahn: Per gallon.

Graham: Yeah, yeah, yeah. Per gallon. So, at 1.25 specific gravity, that’s gonna end up being 10.43 pounds per gallon, and around 1.3 specific gravity it’s gonna be about 10.85 pounds per gallon. And keep in mind, this is gonna vary a little bit. Not only on the specific gravity but on the actual temperature of the solution and on the pressure. But that shouldn’t change it too much.

Ashkahn: Those are marginal.

Graham: Yeah. So, just like the specific gravity is 1.25-1.3 it means that the weight of the gallon of salt water is going to be about 25%-30% heavier than a gallon of regular water.

Ashkahn: Okay. Yeah, that’s-

Graham: And send in that idea!

Ashkahn: Back to the important part of your question.

Graham: And pretty clear cut.

Ashkahn: Right.

Graham: Definitely feel free to run a little science experiment yourselves and prove us right or wrong on that.

Ashkahn: This is one of those rare times we actually know-

Graham: We actually know the answer and it’s concrete.

Ashkahn: Yeah.

Graham: We’re just gonna make this a really short episode. So, if you have any other questions for us, send them to floattanksolutions.com/podcast.

Common Float Tank Issues – DSP 295

Graham and Ashkahn give the skinny on the foibles one my encounter when purchasing a float tank. These aren’t specific to any one manufacturer, but they are useful things to look out for when shopping around for a tank. 

What is Float On’s North Star Metric? – DSP 294

Graham and Ashkahn talk about the guiding principles and metrics that dictate how they run Float On and what they measure for success. While they don’t have any float center secrets, they do provide some useful advice in how to look at numbers, when to pay attention to them, and perhaps more importantly, when to ignore them. 

What Can you Say About Float Centers Closing? – DSP 293

It happens every once in a while that a center you knew closes down and it can seem like a dark omen for the rest of the industry. The reality is that these are individual circumstances that are brought about not because of a major trend as much as just life events coming up. 

Graham and Ashkahn share their take on other float centers closing and what they know about it and how frequently they think it’s occurring. 

How to Build a Green Float Center – DSP 292

Graham and Ashkahn talk about the options available for sustainable options when building a float center, or more accurately, the lack thereof. Unfortunately, the materials necessary to make a float room saltproof and waterproof tend to be very unfriendly for the environment.

The guys break down the specific options available and what to consider when adding green technology to your own center. 

How We Financed Float On – DSP 291

Graham and Ashkahn are asked about how they financed Float On. 

As the guys explain how they started, they go along slight detours to talk about all the mistakes they made along the way and how they’re unsure that Float On could even start today like it did back in 2010. They then go on to explain the pros and cons of the extreme bootstrapping they did to make Float On happen.

The Most Ambitious Float On Project Yet

We have a new endeavor that we’ve been working on in private for awhile now, and we think that it’s going to make a big splash in our salty little industry. After many years of testing behind closed doors, we’re finally ready to take the plunge and release our secret project to you, the floatation community.

The Start-a-Center Giveaway Returns!

The Start-a-Center Giveaway Returns!

Everyone knows that, when it comes to gifts, it’s much more fun to give than to receive. With this year’s Start-a-Center Giveaway, however, I’m not so sure anymore. With over $13,000 in Float Tank Solutions products going to one lucky duck (plus $4,000 worth of goodies from other float industry homies), we humbly suggest that we may have finally tipped the scales in favor of the recipient.

If you’re Charlie, this Giveaway is the Golden Ticket, which I guess makes the Construction Package a Wonka bar and the Ninja Fans are the Fizzy Lifting Drink. So, what do you have to do for a chance at all the Everlasting Gobstoppers?

It’s been three years since our last Giveaway, and we thought that it was long overdue for another one. So, what’s the dealio? The Giveaway is a chance to give a big ol’ boost to a deserving Float-Center-To-Be. This time around, we’re taking things to a whole new level, with over three times the value of products and services being given away. To you. For free.

Dear Everyone: Please reconsider building your own tanks

Dear Everyone: Please reconsider building your own tanks

Look, we get it. Really. Float tanks are expensive – especially for what can seem, from the outside, like a glorified bathtub with spa parts attached. It doesn’t take long to go from, “Why is this so expensive?” to “I’ll bet I could save money by making my own tank!” After you start mulling it over, you get excited. You could be offering something no one else does right now… because it’d be your own creation! How hard can it possibly be?

As experts in only thinking about half of the consequences of our actions (at best), we’d like to say, “Incredibly hard, actually!”
