KEVA(R) Contraptions 200 Plank Set

Setting the ball loose on the funnel section for the first time was incredibly satisfying—the way it spiraled down exactly as planned. My son, who usually gets bored quickly, stayed focused for nearly an hour trying different chute angles. The open-ended, no-rules concept really encourages creative

My kids spent hours adjusting the ramps to get the ball to land perfectly in the funnel, and the planks hold steady even after multiple crashes. Building the track requires real problem-solving, not just stacking.

The moment the ball finally rolled through my entire tunnel-and-funnel setup without getting stuck, I actually cheered out loud. My son and I have rebuilt the track six times today, and the planks hold together so well that even a slight nudge doesn't knock it down.
