In-app challenge
The lunchbox does 180 meals a year
Whatever the lunchbox is made of, your kid eats from it every school day. Before term starts, scan the lunchbox, the bottle and the snack containers, and swap the one that scores worst. Twenty minutes, once a year, for the gear that serves 180 meals.

The 20-minute check
Empty the school bag
Lunchbox, water bottle, snack containers, the pouch stash. Line them up on the counter.
Scan the lot
Each item gets a score and the material reason behind it. Worn and scratched items score honestly.
Swap the worst one
Usually it is the scratched plastic box or the old bottle. The app suggests replacements that hold up.
Why this event exists
School gear gets replaced once a year, in the two weeks before term. That narrow window is when a scan can actually change what gets bought, which is why this challenge runs mid-August through the first week of September.
The exposure math is unusual too. A lunchbox is not one meal, it is around 180 meals a year in the same container, usually warm, often acidic, washed hot daily. Gear that scores mediocre but gets used 180 times outweighs almost anything else a kid eats from. One good swap here carries the whole school year.
The store artwork shows the target state: steel and glass doing the daily work, plastic retired to the jobs it is actually fine at.

What parents find
School gear ages fast: dishwasher cycles, drops and daily use all increase shedding. Scores account for wear.
The scratched sandwich box
Deep scratches shed more with every acidic or warm filling. Steel and glass alternatives score far lower.
The bottle that survived two years
Scratched plastic bottles washed hot every day are among the highest-shedding items kids own.
Warm lunches in plastic
Thermos-style steel wins for anything warm. Plastic containers holding hot pasta transfer the most.
Pouches and squeeze snacks
Fine occasionally. For daily use, the spout plus acidic fillings combination is worth swapping.
