Desafio da Montanha-Russa™

My six-year-old pulled out the challenge cards and immediately started building a coaster that twisted way past the example on the box. The way the pieces snap together makes it easy for him to tweak his design without getting frustrated, and I love that it teaches real engineering basics while he j

We’ve been using the challenge cards to build different coasters each night, and it’s great for teaching actual cause and effect. My son loves testing which designs make the marble go fastest.

My six-year-old can’t put this down — she’s already stacked three coasters from the cards and is starting to tweak the tracks to make her own loops. The engineering challenge is just right for her attention span, and I love watching her figure out why a turn falls apart.
