I Built My Girlfriend a Spreadsheet. Then I Built Her This.
Ana has been obsessed with theme parks since she was a kid.
Not casually obsessed. Genuinely, deeply, encyclopedically obsessed.
She knows the history of every major park in Europe. She knows which rides are worth a 90-minute queue and which aren't. She has opinions about fast passes, about park food, about the exact right moment to hit a coaster to avoid the crowds.
She's been to Disneyland Paris more times than I can count.
And every time she came back from a trip, she'd tell me about the parks she still wanted to visit — parks in Germany, in the Netherlands, in the UK, in Spain. Parks I'd never heard of.
So one evening, I built her a spreadsheet.
Every major theme park in Europe, organized by country, with columns to mark which ones she'd visited and which ones were still on the list. It took me a weekend. It wasn't fancy. But she loved it.
The problem was — a spreadsheet isn't something you carry with you.
The idea that changed everything
Ana carries a water bottle everywhere. To work, to the airport, to the park. It's basically a third hand.
One night I was looking at the spreadsheet and I thought: what if this lived on the bottle?
What if every park had its own little illustration — something she could look at every morning, something she could mark as she ticked them off?
I spent weeks sketching. Every major theme park in Europe, each one inside a hexagon, with its name underneath. Parks she'd been to. Parks she dreamed about. Parks neither of us had visited yet.
For her birthday, I handed her a prototype.
She didn't say anything for a second.
Then she said: "This needs to exist for real."
That was the first Thunderbee bottle.
We're a small brand. It's me, Ana, and a small team that cares way too much about the details. We're not a corporation. We don't have a warehouse full of generic products.
We started because of a birthday gift and a spreadsheet, and we're still doing this because people like Ana exist everywhere.
People who don't just visit theme parks — they collect them. They remember the queues, the smells, the food, the people they went with. Every park is a memory, not just a pin on a map.
The bottle exists for those people.
The Europe Edition comes with stickers for every major European theme park. One sticker per visit. Every one a specific memory. Built to last the years it'll take you to finish it.

This isn't a souvenir. It's a tracker.
Most theme park merch ends up on a shelf.
This goes with you — to the park, to work, to the airport on the way to the next one.
Every time you fill it up, you see the parks you've been to and the ones still waiting. It's a reminder that there's always another adventure ahead.
Ana still has the original prototype.
The rest of them are yours.
