TEST ONLY: a cardboard ramp that sorts acorns into small, medium and "chonky" cups.

// What I'm building
This is a test project, not a real build. It's here to check that the website pipeline works, and it will be deleted.
What it does: A cardboard ramp with three different-sized holes that sorts acorns (or pom-poms) into small, medium, and "chonky" cups as they roll down.
How it was built: A cereal box cut into a long ramp, three holes traced around bottle caps of different sizes, paper cups taped under each hole, and a googly-eye "squirrel inspector" glued at the top.

- Cereal-box ramp
- 3 hole sizes: small, medium, chonky

// Build Log
Test #1 — first try
- WHAT I TRIED
- A cereal box cut into a long ramp, three holes traced around bottle caps of different sizes, paper cups taped under each hole, and a googly-eye "squirrel inspector" glued at the top.
- WHAT BROKE
- Every acorn skipped the holes and rolled straight off the end into the dog's water bowl. The googly eye also fell off and was never seen again.
- THE FIX
- Taped a popsicle-stick bump in front of each hole to slow the acorns down, and tilted the ramp a little less. Now about 8 out of 10 land in the right cup.
Round 2 — update
- WHAT I TRIED
- Same cereal-box ramp from round 1, with the popsicle-stick bumps in front of each hole. For this update a second popsicle stick was stacked on each bump to make them "extra slowy-downy."
- WHAT BROKE
- The taller bumps worked too well. Instead of slowing down, the acorns hit them and launched straight up like tiny rockets, sailing over all three cups. One landed in a cereal bowl. The CHONKY cup stayed empty all afternoon.
- THE FIX
- Took the extra sticks back off and wrapped each bump in a strip of felt so it's soft and squishy. Acorns now bump, wobble, and drop in. Score went from 8 out of 10 to 9 out of 10, and the CHONKY cup finally got its first acorn.

Round 2
A cardboard ramp with three different-sized holes that sorts acorns (or pom-poms) into small, medium, and "chonky" cups as they roll down. This is an update to round 1.
