Idea Of The Day - Build the Planetarium Where People Float Instead of Sit.

In partnership with

GM. This is Needs to Exist (aka NTE), delivering you a startup idea that turns planetariums into immersive, floating cosmic experiences.

NTE Pro: 6,500+ ideas — because in the AI era, ideas are the real leverage.

Swim Through Space Experience

The One Liner

Swim through space.

The 140 character tweet (or X) version

Planetarium, but you float in a heated saltwater pool under the stars with underwater sound and a swim-up bar. Stargazing just leveled up.

The Longer Story Version

The Problem

Planetariums are cool.

But they’re passive.

You sit in a chair.
You look up.
You leave.

It feels educational. Not transformational.

Meanwhile, immersive art exhibits are selling out. Rooftop cinemas are packed. Projection shows are turning warehouses into “experiences.”

The dome isn’t broken.
The format is.

Younger audiences want immersion.
Adults want playful, elevated nights out.
And traditional theaters? They’re fighting for relevance.

Stargazing feels distant.

It should feel embodied.

The Solution

Replace the seats with a giant donut-shaped heated saltwater pool.

Guests float comfortably on their backs while the dome projects galaxies, deep space journeys, concerts, films, psychedelic light shows.

Underwater speakers create full-body audio.
Light ripples across the surface.
There’s a swim-up bar in the center.

It’s not a planetarium.

It’s a cosmic float experience.

Highly photographable.
Highly eventizable.
Highly premium.

One venue could run:

– 18+ night sessions
– Guided space meditations
– Live DJ dome concerts
– “Float Under the Stars” movie nights
– Brand-sponsored space events

It becomes a multi-use experiential venue disguised as science.

How We’d Build It

Phase 1: Prove People Want It
Expertise: scrappy founder + vibe coding

– Use AI tools like Midjourney and Runway to generate hyper-realistic concept visuals
– Build a landing page in Framer or Lovable in one weekend
– Use AI-generated render walkthroughs to simulate the space
– Run Meta + TikTok ads targeting immersive art lovers
– Collect deposits for early-access tickets in one flagship city

Goal: Validate demand before building anything physical.

Phase 2: Pilot One Flagship
Expertise: experiential operator + architect

– Partner with an existing dome venue to retrofit a temporary modular heated pool
– Use projection tech + spatial audio (L-Acoustics, d&b Soundscape)
– Limited-capacity premium pricing
– Influencer previews + event creators
– Pre-sell themed nights

Goal: Sell out consistently.

Phase 3: Scale the Format
Expertise: brand builder + operations machine

– Create a replicable build-out kit
– Franchise or license to major cities
– Partner with streaming platforms, DJs, festivals
– Develop branded “cosmic float” IP nights

This becomes the Soho House of immersive space.

Why It Needs to Exist

Experiential venues are winning.
Wellness and entertainment are merging.
Projection tech and spatial audio are affordable.

People don’t want more content.

They want to feel something.

Traditional theaters are struggling.

Immersive, slightly absurd, premium experiences are thriving.

And if someone builds the first one right?

Every city will want to float under the stars.

The Insurance Company War Room

Premise
A sterile conference room. Fluorescent lights. Someone clicks to a slide that says: “Planetarium. But everyone’s floating in a heated pool.”

Silence.

Cast
• The Head of Liability
• The Actuary Who Hates Fun
• The “Actually This Could Print Money” Analyst
• The Marketing VP Secretly Excited

Head of Liability:
“So this is a dark room. With water. And alcohol.”

Actuary:
“Statistically speaking, this is a lawsuit with ambient lighting.”

Marketing VP (trying not to smile):
“Or… it’s the most Instagrammable venue in the city.”

The debate gets real.

Is this a lawsuit factory or a cash machine?
Because if you can’t insure it, you can’t build it. But if you can insure it, no one else will want to touch it, which means pricing power.

Does higher perceived risk actually create premium positioning?
Skydiving didn’t die because it was risky. It became expensive.

Can safety be part of the spectacle?
Required float devices that look like cosmic rings. Lifeguards dressed like astronauts. Depth limited to “standing plus drama.” Alcohol capped. Timed entry waves. It’s not chaos, it’s engineered chaos.

Then someone says it:

“What if insurability is the moat?”

If you design the experience around what underwriters will approve, you create a template competitors can’t easily copy.

Adults in water are unpredictable.
But adults paying $85 for a curated cosmic float experience? Different energy.

This isn’t about removing risk.
It’s about packaging it.

And if the insurance team eventually says, “We can price this”?

That’s when you know you might have something big.

What if your next million-dollar idea is hiding in plain sight?

NTE Pro is 6,500 startup ideas deep — weird, obvious, uncomfortable, unfair advantages waiting to be built. Not “10 AI tools you can try.” Real leverage. Real angles. Real businesses someone will build with or without you.

In the AI era, execution is cheap. Ideas are scarce.

Something important just happened.

A company quietly filed to raise money.
A founder shipped a product at 2am.
A competitor you didn’t know existed just launched on Product Hunt.

WhoFiled catches these moments as they happen and filters them through what you care about. Not what’s trending. Not what’s loud. What’s relevant.

Start with one company, one market, one thesis.

We’ll surface the filings, launches, GitHub activity, Reddit chatter, and early signals that matter before they become headlines.

Execution is fast now. Windows are short.

WhoFiled helps you move while you’re still early.
