Review on π¬ Physics Fun Marble Add-On by Marble Genius by Jason Richardson
The generator is worth the price, but not all parts work well.
I bought this kit primarily for the alternator to make assembly with my daughter difficult and these parts are excellent. Unfortunately, the green S-shaped slide with open rails does not have enough buoyancy to keep the balls moving and sometimes they get stuck. Loop-d-loop is cool, but the balls fly through it so fast it's hard to see it in action.
- Excellent construction
- Problems
