How Long Until My Coffee Is Cold? Banana Prank

WHAT !! 18,045 kg of bananas, I didn't order anything
CANCEL !! CANCEL !! Oops Too Late Buddy
Ohh !! Analyzing Coffee Temperature Dynamics
I wonder how long it would take !!
Entering my room temperature !!

Inspiration

We were inspired by the sheer pointlessness of modern web tools and the beautiful chaos that ensues when humor meets fake utility. The existential dread of cooling coffee was the perfect cover for something entirely nonsensical. Also… bananas. Lots of bananas.

What it does

You enter the room temperature to estimate when your coffee will go cold. But instead of a real calculation, after five suspenseful seconds, you’re hit with a completely irrelevant Amazon-style confirmation that you’ve just purchased 18,045 kg of bananas. Below it? A bold "That's bananas" pun and fake buttons to “Track Order” or “Cancel. (Oops its too late)”

How we built it

We built it using the amazing and outstanding ai coder called Bolt.new

Challenges we ran into

Finding the right number of bananas to be hilariously unrealistic but still technically feasible for comedic effect.

Balancing the UI between “this might be useful” and “this is absolutely a prank.”

Accomplishments that we're proud of

We made people laugh.

We created a website that makes you question your life decisions in five seconds or less.

The fake Amazon UI is weirdly convincing.

What we learned

Humor can be a UX feature.

People will genuinely enter data into anything that looks like a tool.

Bananas are surprisingly versatile as a comedy prop.

What's next for How Long Until My Coffee Is Cold? Banana Prank

Add random fake purchases (e.g., 600 gallons of glitter, 900 inflatable flamingos).

Launch an NFT collection of distressed coffee mugs.

Implement a “Speedrun to Cold Coffee” leaderboard.

Probably nothing. And that’s kind of the point.

INT. HACKATHON ROOM

We sat there. Caffeinated. Paranoid. Wondering if our coffee was already cold.

Then the idea hit: What if we made a website that pretended to calculate when your coffee goes cold... but instead, just tells you you’ve bought 18,045 kg of bananas?

A completely useless prank, wrapped in the facade of a useful tool.

Thus began our descent into chaos.

🛠 The Tools of Chaos

We used only bolt.new — no setup, no bloat, just a blazing-fast way to prototype weird ideas. It became our launchpad for one of the most unnecessary websites on the internet.
