The neighbour with a drill might be next door.
A drill may sit unused in one home while a neighbour needs it for ten minutes. Pumpipumpe makes that hidden availability visible on a surface people already pass: the mailbox.
CH SwitzerlandIn practice. A Swiss sharing initiative by designers Lisa Ochsenbein and Sabine Hirsig uses mailbox stickers to make available objects visible.
What to keep in view
A sticker signals willingness to share; it does not guarantee availability, trust or successful loans. The initiative makes contact easier but leaves the relationship with neighbours.
A tiny sign starts a conversation
Pumpipumpe began in Bern in 2012 through the Meteor Collectif team. Residents put illustrated object stickers on their mailboxes to signal what they may lend. A neighbour can see that a ladder, drill or other object is nearby and ask its owner. The project later added digital support, but the simple mailbox signal is its defining intervention. Designers Lisa Ochsenbein and Sabine Hirsig made the mailbox the interface: a familiar place that neighbours already pass.
The ordinary mailbox became a visible index of what neighbours could share.
Give sharing a local address
Our reading: useful capacity is often close by but invisible. The stickers use a shared, everyday surface to create a local invitation without relocating all objects to a managed store. Visibility is only the first step, though: asking, agreeing terms, returning the object and trust still matter.
