At 3:07 a.m., Kai opens his Notes app and types: One sensor. One garden bed. Stop wasting water.
The idea has been following him for weeks. It is not on his official school-project list, but he sketches it during lessons and thinks about it while brushing his teeth. Part of him wants to call that feeling destiny.
Instead, he calls it a reason to test.
Kai knows basic coding, hates seeing the community garden overwatered, and already knows the coordinator. He builds the smallest version he can: one cheap moisture sensor, one plant bed, and one dashboard.
The first readings are useless. Rain gets into the housing. The graph says the soil is dry while Kai is standing in mud.
A science teacher helps him protect the sensor. Then the garden coordinator looks at the dashboard and says, "This is cool, but volunteers won't check another app. Can it text us?"
Kai changes the prototype.
His gut was not correct about the final solution. It was useful about the direction. The idea contained a real problem, a real interest, and a real person he could help.
Intuition opened the door.
A small test let reality into the room.
