Tap the things you have, and I'll show you the projects you can start today, and the ones that need just one more thing.
What science fair projects need most
Counting across all 118 of Peabody's projects (water from the tap is never counted: every house has it), these come up most often:
- 🩹 Masking tape, to mark lines: 61 projects
- ⏱️ A stopwatch or a kitchen timer: 46 projects
- 🥛 A measuring cup: 33 projects
- 🥛 Clear plastic cups, all the same size: 32 projects
- 🖍️ Crayons or markers: 32 projects
- 📄 Paper: 29 projects
- 🥄 A spoon: 25 projects
- 📏 A tape measure, or a long ruler: 25 projects
80 of the 118 projects cost nothing if you have the usual kitchen and junk-drawer things, and none costs more than a few dollars for what most houses lack. Tick the things above and the finder does the counting for you.
A kit in a box, or the kitchen?
Boxed science fair kits are sold one project at a time, and a single one can cost forty dollars or more (Home Science Tools' science fair page, read 30 October 2026). A kitchen project is just as real a fair project: one thing changed, one thing measured, three tries at each level, and every sheet the fair asks for. When a project is one thing short, the finder makes a shopping list for that one thing, with how many you need.
Short on time as well? Try the weekend projects, or let Pick my project choose one in four taps.
