International Sandwich Authority · Deployment control
Make a sandwich.
An Earth Sandwich takes two people at opposite ends of the planet. One of you starts it and gets a Bread code; the other joins with that code. Then, each at your spot, you both deploy a slice from this page within five minutes of each other. The photo is the deployment.
Your sandwiches ON THIS DEVICE
Start a sandwich I’M ORGANISING
You get a Bread code and an invite link. Still looking for your other slice? Ask around on social media, agree on a place and a time, then send them the link or just the code.
You’re invited.
Someone wants you as the other slice of this sandwich. Joining takes the second seat: you’ll see each other’s distance from a perfect sandwich, and deploy your slice from this page.
Started this sandwich yourself? Open the personal link from your lobby on this device instead. This invite link would take your partner’s seat.
Your sandwich.
Bread code SHARE WITH YOUR OTHER SLICE
Your personal link DON’T SHARE THIS ONE
This link is your seat. Open it on the device you’ll take the photo with (a phone, or a laptop) and your seat moves there. Keep it to yourself: whoever opens it takes your seat. It stops working once your photo is in.
Slices PRESENCE
SLICE A
SLICE B
Wrong person in seat B? Reopening it removes them, and your code and invite link work again for someone else. Only possible until they deploy.
The window FIRST SLICE OPENS IT · 5 MIN
When the first slice lands, the other side has five minutes to deploy theirs — that keeps both photos inside the official tolerance. Deploying opens the camera: the photo is the deployment.
A photo file is graded by its own GPS data. Without GPS data the slice is an Anecdote, which can’t pass.
Bread and ground in frame (Sandwich Law § 3.1). Position and UTC time are recorded at the shutter — this is Certified evidence.
On a laptop: tilt the screen down until the camera sees the bread on the ground.
Withdraw your slice SANDWICH LAW § 8.3
Changed your mind? Withdrawing deletes your photo and position right away, takes the pair off the public board and out of the review queue, and ends this sandwich for both slices. It can’t be undone, and copies anyone already downloaded or shared are beyond our reach. This browser remembers your slice, so you can also come back to this link later to withdraw.
