“Why do you always carry a knife?” My great-grandfather told my grandfather: “A real man always carries a knife.” My grandfather told my dad. My dad told me. Now that I’m a dad, I get it. Today, I turned an Ovomaltine bottle into a spill-proof, straw-ready hydration device.

Sorry, no dad hack last week — I was busy biking, fishing, and doing what dads do best: fixing problems with whatever’s lying around. 🛠️ We hit a Swiss Grillplatz with the kids. Fire? One match + 100ml burner alcohol + dry wood = 🔥 But: no grill tongs. So I made some. 2

Got a flat on our Thule Chariot bike trailer. Realized: not just the tube - the whole tyre was done. Lesson? Don’t wait till you’re stranded with kids onboard. 🚲👶 Swapped the tyre, pumped it back up with my fav tool: ➡️ Xiaomi Portable Electric Air Compressor ✅ Up to 10 bar
