Cardboard and box projects
| Project | Minutes | Grades | What it shows |
|---|---|---|---|
| Wall Marble Run | 30 | K–3rd | Things roll downhill, and a gentle slope makes a slower ride. |
| Shoebox Guitar | 30 | K–3rd | A tighter, thinner band wiggles faster and sounds higher. |
| Hydraulic Robot Arm | 120 | 5th–8th | Push water into one syringe and it pushes the other, because water won't squash. |
| Tube Flashlight | 40 | 3rd–8th | A switch is a gap in the loop that you can open and close. |
| Chain Reaction Machine | 45 | 2nd–8th | A little push sets stored energy free, and it passes from one thing to the next. |
| Balloon Car | 45 | 3rd–8th | Push air out the back, and the air pushes the car forward. |
| Skeleton Hand | 40 | 1st–8th | Fingers bend when a muscle pulls a tendon, a strong string that runs to each fingertip. |
| Spooky Shadow Theatre | 45 | K–8th | Light goes in straight lines, so a puppet that blocks it throws a shadow. |

Questions parents ask
What can kids make from cardboard?
A shoebox guitar, a balloon car, a hydraulic arm that lifts with water, a skeleton hand and a shadow theatre. The table lists each one with its time and grades.
What do we need?
Cardboard, a box or a tube, plus tape, string or straws for most of them. Each project page lists its materials and tools, and says what can be swapped.
What ages are the cardboard projects for?
About 6 to 12. The Grades column says which grades each one fits, and younger children can build with a grown-up.
Are these projects free?
Yes. Everything here is free through the end of 2026, with no ads, no sign-up and nothing to download.
